Happy Thanksgiving from LIM Innovations

This past year LIM Innovations® celebrated five years of empowering the limb loss community to live beyond the confines of the rigid socket. Breaking with convention, our adjustable Infinite Sockets™ have enabled over one thousand individuals to regain control over their own comfort. Being freed from the confines of the rigid socket has been life-changing for many of our wearers, and we are honoured to be part of their journey.

With Thanksgiving approaching, we are counting our many blessings. We are grateful for the wonderful community that we are fortunate to serve. We are proud that our Infinite Sockets™ continue to improve the prosthetic experience and has been empowering for our LIM Legends to live their best lives.

We are grateful to be affiliated with a variety of nonprofits dedicated to helping the limb loss community. Through our Silver Sponsorship of the Amputee Coalition, LIM Innovations helps to further empower the community. The Amputee Coalition provides resources and peer support for all individuals impacted by limb loss and limb difference. We are proud to support their efforts.  

Through the Atlas Run app, LIM Innovations is able to provide continued support for Range of Motion Project (ROMP). ROMP provides prosthetic devices for individuals in developing countries. Through providing prosthetic devices, the ripple impact of ROMP extends past the individual and into the family and, in many circumstances, into the entire community.  

This past year we were delighted to work with Upright Africa to provide an Infinite TF (above knee) socket for Prince. Upright Africa works to empower individuals with disabilities living in remote regions of Africa. More information about Prince’s story can be found through this link.  

In keeping with the spirit of giving, this year LIM Innovations has decided to dedicate our holiday party to promoting the missions of ROMP and Upright Africa. At our holiday party on December 14th, attendees will have the opportunity to learn about the work of both organizations and will be introduced to six patients in need of care. Through a silent auction, funds for devices will be raised to sponsor each highlighted patient through the prosthetic process. Our holiday party is open to the public and complimentary tickets can be claimed through this link.

This past year has been one of great growth for LIM Innovations. Through our move into a new office, expanding our staff and securing additional funding, we are setting the stage to continue to develop innovative and empowering devices for the limb loss community. We are thankful to be part of this wonderful community and appreciate the trust that has been put in us by those who wear our Infinite Sockets.  

We wish you all a happy and safe Thanksgiving.

Building the Community – Adaptive Yoga

“Adaptive Yoga

If you haven’t heard yet, LIM Innovations is building more than prosthetic sockets; they are building community. This past Saturday, April 22, we held our first community gathering at LIM HQ. 23 people joined together in an Adaptive Yoga class. Adaptive Yoga is variations of traditional yoga poses, making them accessible and inviting. Yoga, in Sanskrit, comes from the root yuj, which means “to join” or “to unite.” Yoga is the union of body, mind, and spirit. Through yoga asanas (postures/poses), one develops concentration and awareness of their body and mind. Yoga also teaches us to listen to our bodies. Saturday’s class was all about learning to listen and creating space in the body.

Ambassador

As a part of the LIM Ambassador program, community events will be held at LIM’s HQ on a monthly basis. This is an opportunity for fellow amputees, family, friends, caregivers, and others in the community to join together. Most of the events will be led by one of the Ambassador’s.

Why is Yoga important to me?

We live in a world where many of us are busy meeting deadlines for work, shuffling kids around, taking care of our families, taking care of our homes, and in general giving our time to others. When and how do we create time for ourselves? For me, yoga has been the foundation to self-care. My body, mind, and soul are fueled and nurtured from a sustained yoga practice.
Thank you to the many participants who came to our first community gathering at LIM Innovations. It was an honor to share the time with you!” – LIMLegend Lindsay Moorehead

Lindsay's Learning Curve

Living an extremely active life: running, biking, yoga,  you would never have imagined the story behind Lindsay. From struggling to concentrate in class, Lindsay set out to pursue an active life. During the challenges she faced, she realized that that her teachers may have jeopardized her learning. Upon moving comfortably in her Infinite TT’s she now wants to set out to help people in her own way. 


As a kid I loved being outdoors, in nature, and exploring. Growing up in a small rural town in Iowa I spent a lot of time outside building forts, running through the trees, making up games from objects found in nature, and riding my bike with my sister and neighborhood friends. The love of nature made sitting in a classroom difficult. I looked forward to any opportunity to be outside, running around, or biking. In 6th grade I began running cross-country after quickly realizing I didn’t have the coordination for basketball or volleyball. At my first cross-country practice I showed up and ran in basketball shoes. Even today, I remember how bad my legs hurt and how I thought I would never run again. I stuck out cross-country and of course, got a pair of running shoes. Over time, running became easier; I realized I wasn’t going to die running and before I knew it, running became a passion. I loved the sense of being outside in nature with the breeze on my face and the sun on my skin. I was a dedicated runner who would even run in the winters, in the snow. I would throw on my favorite green running tights, a pair of shorts, a turtle neck, sweatshirt, a beanie, and when icy, my track cleats. Running didn’t really require anything but myself to do and I liked that. It was simple. In addition to running I enjoyed riding my bike. From the age of 12, I had participated in RAGBRAI, a 600-mile week long bike ride that goes across Iowa annually. It was fulfilling to be outdoors running and cycling.

From a young age I knew I wanted to explore the world beyond the small town I grew up in. After graduating a semester early from high school, I moved to Des Moines, IA, where I experienced living on my own. I worked at the Olive Garden waitressing and bartending. While learning some of the responsibilities of becoming an adult the desire to be outdoors was still strong. I addition to my often long hours at work I always made time to run & cycle. As a young adult my life revolved around work and exercise, and unfortunately, I didn’t value sleep.

On April 25, 2001, I was on my way to meet a friend, after finishing my work shift around 10pm. As I traveled north on the interstate I remember feeling tired and sleepy. I began opening the window to feel the cool evening air on my face. I also turned up the music louder in hopes the music would energize me. Before I knew it, I had missed my exit off the freeway. In Iowa, where the exits are several miles apart, I had to go up to the next exit (almost 10 miles out of my way) to turn around. I remember taking the next exit, coming across the freeway, and the next thing I remember, I woke up confused wondering where I was. I thought to myself, “Where am I and how did I get here?” I had fallen asleep behind the wheel of my car and never made it back onto the freeway. My car went off the side of the road into a creek bed. I was unaware of the extent of damage my body had endured, as I wasn’t in any pain. As days passed I felt my energy levels dissipating. I even noticed the dire state my legs were in. My car was out of visibility of the freeway traffic. I called out for help, but no one could hear me. Little did I know my family had reported me missing and photographs of me were on both local and national news. Five days later I was found trapped in my car that was partially submerged in water. At that point I was exhausted and cold. On the fifth day I was beginning to wonder if I’d ever be found. I was transported by helicopter to the University of Iowa Hospital and Clinics – where they said they would be amputating both my legs below the knee. My family was in shock, but I had come to terms with the possibility of amputation while in the wreckage.

It was a little over two months, post-amputation before the possibility of prosthesis arose. I remember the eagerness to run on the first day in my new legs rushing through my body. On my Dad’s birthday, July 18, 2001, came my opportunity to walk. I quickly felt exhausted trying to piece together my new task. Relearning to walk was much more strenuous & painful than I had originally thought. My plans to run on the first day in my new legs didn’t unfold how I had anticipated. To this day, it’s still interesting to me, how my residuum is soft to the touch yet as soon as you bear end weight, the pain is atrocious. On my first day in my new legs, I left with the image of how proud my parents were. I will never forget that moment. I also left knowing the only way to get better at walking was to walk; one foot in front of the other. And that I did!

Due to my high profile case, I only completed two weeks of therapy, as I was scheduled to feature on Good Morning America and the John Walsh show in New York. Traveling as a new amputee was tiring. It required diligence to rest and elevate my legs when needed, as the muscle groups I was using were previously neglected. It took a year before I was walking effortlessly; walking without thinking about it. That was when the shrinking took its toll. I ended up spending weeks wearing a 36-ply- sock. I had no idea how my legs would change as I began walking more or what to expect in the first year post-amputation. No one had told me 36-ply socks is WAY TOO MANY!

Upon being refitted with a new prosthesis, I was given the opportunity to try a pair of running blade. I was reignited with my love for running. Since becoming an amputee, I’ve had many opportunities to run, cycle, and do physical activity outdoors. One of the biggest challenges has been the need for socket changes and maintaining a well-fitting prosthesis. I dreamed of the day when I would have multiple prosthesis, to capture my wide array of fluctuation. That’s when I questioned, “Why aren’t there any adjustable sockets being made?” It shocked me that in the 21st Century, adjustable sockets were nowhere to be seen.

I was then introduced to LIM Innovations, who asked if I’d be interested in trying their below-the- knee prototype. This was an exciting opportunity for me. It was like a dream come true. I felt like the years of socket issues and residual limb pain were worth the wait.

It can take some time to get the ideal fit with the Infinite TT’s, however it’s worth it down the road when you know you have the capacity to make subtle changes. These days, my limbs require less maintenance and I don’t always fiddle with the setup. It is very reassuring knowing that I can make changes to this socket as my limb changes. The sturdiness of the socket is impressive and represents the shape of a conventional socket, but when you adjust the Infinite TT via air bladders and/or BOA, it’s like having different sockets.

Now, I’m back to consistently walking 6-10 miles a day, feeling great and not in pain, which is such a treat! For many years I took it for granted my ability to walk comfortably in addition to running and cycling. It feels great to be active again! I am excited to be able to comfortably move in and out of side-plank in my yoga classes. Completing this can be difficult and requires a well-fitting socket in order to be able to put that much pressure through the socket. The best thing is, the Infinite TT’s can cope with this pressure. It’s an exhilarating feeling to feel like I can move freely; without unnecessary limitations.

Going forward, I really want to work with more amputees in yoga practice. There is still the perception that you need to be skinny, fit and flexible, to practice yoga. I was once one of those individuals, but it’s not at all the case. After studying yoga, I have a deeper understanding of its roots and true meaning. Yoga is, can, and should be accessible to everybody no matter your shape, size, race, religion, or socio-economic status. I was re-inspired to delve deeper into learning to work with a broader population of people after the organization Accessible Yoga started last year. I want to utilize my life experiences to be a part of the change in perception of yoga. The practice is truly for everyone!

Breaking Down the Infinite TT

The Infinite Socket TT is a custom-molded, modular, and dynamic socket system. The combination of a modular frame and advanced pressure distribution system enables clinicians and patients to adjust the socket. Pressure distribution and biomechanics are designed in response to activity demands, pressure areas, and shape change.

With so many features, the Infinite Socket TT is like no other below-the-knee prosthesis. Watch the makeup from the designer’s behind this revolutionary socket, and hear first hand from the amputees that helped shape the design.

Nathan the Invictus

Nathan was one of our very first adopters of the Infinite Socket in the UK. He has showcased the Infinite Socket with the Invictus Games, and his determination has stuck firmly in the mind of everyone at LIM during his interactions with us.


“I served in the British army for ten years. During my third tour of Afghanistan I was blown up by an I.E.D that resulted in me losing my left leg below the knee and above my knee on the right. After spending a few months recovering from my injuries, and numerous operations later I started my rehabilitation process to learn to walk again. It took me around two years to be confident in using prosthetics on a daily basis. I was lucky I had the best prosthetics available to me, yet sockets were the main issue. Losing weight and volume around my residuum required a new socket. When the fit was right again, I would put weight on and a new socket would be necessary. I caught MRSA 7 times and have had 29 surgeries so far, each resulting in the revision of my limbs, resulting in more sockets.

It was then that I was introduced to LIM Innovations about six months ago where I had an opportunity to try a LIM Infinite Socket for my above knee prosthesis. After a few teething problems, which were promptly rectified by my clinical team at Headley Court Medical Center in England, I have been using my new socket every day with little discomfort. I can confidently say I wish I had tried the socket earlier as it’s been really good for me. With an intimate fit, that flexes with my limb as I walk, I can carry out my daily activities without skin breakdown and painful sores that affect my gait.

With the release of their below knee prosthetic, the ‘Infinite TT’ around the corner, I am hoping they carry on with the same adjustable, dynamic features that makes the Infinite Socket so unique to the individual wearing it. I will be pursuing the acquisition of the Infinite TT for sure.

I recently went to San Francisco with the team from Invictus Games and the British Benevolent Society to have a guided tour of LIM’s facility. I met the whole team involved from start to finish in the production of my socket and it’s great to see the care they offer on a daily basis. They hosted a happy hour event based on a Veteran’s road to recovery and what they do to become more involved in a civilian capacity. I was invited to speak in front of 85 people who intently listened to my story and offered support. It goes to show the level of respect that LIM has for every one who has either been affected by amputation or wishes to achieve more freedom than ever before.”

Relationship Goals

The patient-prosthetist relationship is characterized by the socket fit experience. This means that a prosthetist’s signature is our socket design and the quality of clinical care that supplements it. As such, the Infinite Socket uniquely partners three people – a LIM Clinical Specialist, a prosthetist, and a patient user. The three of us work closely to build this crucial relationship for success. My job as a LIM representative is to direct and manage our trio’s knowledge, perceptions, and needs. There are many things that create and maintain a happy outcome. I often make the analogy to our clinical partners and #LIMLegends that starting this relationship is much like a first date.


Copy of Peak 1 - Janna King -- FaceTime Anthony & Joe Mahon12


The prosthetic socket so intimately represents our literal and conceptual expectations, much like two individuals coming together. They overlap common interests with the expectation to discover something new. Despite unfamiliarity, both people want to have a good time and learn new things in the process. A prosthetist approaches a fitting with an established set of clinical expertise and principles. The patient actively participates by providing feedback and functional cues. Together, this patient-prosthetist date evolves like any close relationship.

As a LIM Clinical Specialist, I enter the patient-prosthetist formula at various stages. I carefully navigate and adapt to the existing relationship, sometimes remotely via online support and sometimes visiting in person. It’s a delicate approach, but also a privileged one. From it, I always learn new clinical styles and use this insight to become more relatable in future encounters. Introducing myself in this way has been warmly welcomed at all of my LIM Supported Fittings (LSFs) domestically and internationally. This is especially important given the pressures imposed upon the patient and the prosthetist by the payor process. These realities can often create confusion and miscommunication between me, the prosthetist, and the patient. Things only get more complicated when introducing personality and product nuances. Herein lies the critical aspect of managing our date.

Providing clinical support is very different for a socket product than a prosthetic knee joint or foot. I mentioned that the socket is a prosthetist’s signature, while the patient relies significantly on the socket interface as the primary means for walking. So, this puts me in a very strategic position to support the clinical relationship apart from technical troubleshooting. I view this opportunity as a way to bond over professional and industry challenges faced by the patient and prosthetist. It’s a think tank, it’s a support group, and it’s a moment to connect. This differs very much from my personal experience with prosthetic device manufacturers. Our industry has cultivated a vendor culture where service and support are concretely defined by the product itself. Establishing and sustaining the Infinite Socket’s impact at various levels is a much larger responsibility. In this way, I find my role as a Clinical Specialist to be very dynamic.

Like with any date or new experience in life, long term successes are built from thoughtful and genuine attention to the relationship. Thank you to all our partners and #LimLegends for this opportunity.

Introducing LIM Capture

To clarify;
What we call “digital fitting” is not what the industry calls digital fitting.  If fact they don’t say digital fitting they typically would categorize this under CAD/CAM which would be a CAD (Computer aided design) modification and CAM (computer aided manufacturing).  That concept has been done before only the CAD and the CAM typically used is way different; they would digitally modify then carve a shape and then use traditional fabrication to make a socket.  We use CAD/CAM in the following way that has never been done before:
1. We collect user measurements, images, and/or an impression from the ordering practitioner via our online ordering process. (this type of ordering has been done before only we are doing it in our own branded way)
2. We digitally modify the mold per patient needs and the order (not a new step – been done before).
3. We “digitally fit” our dynamic modular socket components to the modified mold using a proprietary algorithm and software (this is a new process – never been done)
4. We utilize a proprietary and renewable manufacturing technique to custom-mold our socket to the user’s needs and clinician order then ship the socket for fitting and adjustments.
5.  The finished Infinite Socket offers adjustable that no other socket has which allows the socket fit to be fine-tuned for maximal comfort and optimized function.

Example post:

…LIM Innovations is offering a unique and revolutionary path to getting amputees fit with comfortable and adjustable prosthetic socket interfaces. They first collect  measurements, images, and/or an impression from the ordering practitioner via their streamlined online ordering process.  LIM then digitally fits their dynamic modular socket components to the modified mold using a new and proprietary algorithm and software. LIM can then utilize their proprietary and renewable manufacturing technique to custom-mold the Infinite Socket to the user’s needs and clinician order. The finished Infinite Socket offers adjustability that no other socket has which allows the socket fit to be fine-tuned for maximal comfort and optimized function. ….

Stories and Innovation

Here at LIM Innovations we pride ourselves on the diversity of our team. We have a fantastic group of engineers, designers, machinists, clinicians, and amputees with relevant experience in the field. With such a diverse group working behind the scenes, we invite you to join one of our staff members each week for an in-depth look at what they bring to table. It is our goal to provide our loyal reader’s a behind-the-scenes look at LIM Innovations. Christian Johnsen, Video Editor, picks up the pen this week to discuss the videos created to showcase the personal stories of amputees and the technology that improves lives.


Before working as a video editor for LIM Innovations, my knowledge of the prosthetics world was very limited. A few years ago, a close friend was employed at UCSF as a Prosthestist, which gave me a glimpse into what seemed like a rather obscure field of medicine. My few visits to his clinic were eye opening but it wasn’t until I began editing videos that I could truly see.

Anyone who has edited video will know that it is a fairly tedious process, reviewing footage many times before deciding to use it, cut it, and where to plug it into the storyline. Through this process of review I became a de facto student of prosthetic technology, human anatomy, design principles, and most intimately, the personal narratives attached to the people in the videos.

Each amputees set of circumstances is unique, however, there is a common thread that ties everyone together. That common thread is overcoming adversity and getting back to a quality of life where people are free to do what they want. This is at the heart of the storyline that we aim to capture.

So, what is it that allows someone to reach this goal after amputation? Well, determination is the first thing, followed closely by a level of comfort. With comfort comes confidence, and from confidence comes success. The Infinite Socket provides a level of comfort that allows amputees to have the confidence to live without limits.

Each time I’m introduced to a new story from the perspective of an amputee using the Infinite Socket, I see and hear how it has made a vast difference in their life. This is an incredibly powerful thing to witness again, and again, and I’m happy to get to share these stories with the world.

The visuals illustrate a powerful story, people tell a powerful story, and innovative technology speaks for itself.

Prosthetics and Kintsugi

Here at LIM Innovations we pride ourselves on the diversity of our team. We have a fantastic group of engineers, designers, machinists, clinicians, and amputees with relevant experience in the field. With such a diverse group working behind the scenes, we invite you to join one of our staff members each week for an in-depth look at what they bring to table. It is our goal to provide our loyal reader’s a behind-the-scenes look at LIM Innovations. Scott Jurgens, Production Technician, picks up the pen this week, comparing amputation to the Japanese art and philosophy of Kintsugi.


 

Everything around us is in a constant state of breaking apart and coming back together. With an amputation, a fragmented sense of self can lead to existential dilemmas. Our bodies, with the right care, are long lasting and resilient. We may break bones or tear flesh, but in the end we recover and become stronger.

Today, I would like to bring up the relevance of the art style and philosophy of Kintsugi, to discuss its relevance on how we view prosthetics. Kintsugi is a Japanese word for Golden Joinery, an art form derived from piecing together pottery with gold or other precious metals. This art form is meant to emphasize imperfections, resilience and life’s journey. This technique displays a story of repairing an object to its original function after transformational rebirth. One could argue that our bodies are in a constant state of Kintsugi, that all we truly have is our naked bodies and the story it tells of our life’s journey through scars both physical and mental. Humanity’s inherent desire to care for each other has led to major advances in medicine and healthcare, prolonging resistance to inevitable loss of function or life. These developments allow those who are unable to live normally to have hope. The era of putting down the lame dog has passed, we are now in the era of repairing and sustaining.

At this point in time, when a limb is lost, and will power is not, why should anyone suffer a body that doesn’t meet their envisioned desires and demands? The prosthesis is the gold in our broken bodies, aesthetically pleasing as a story of human will and ingenuity used in repairing the most basic of needs. It is through the beauty of perseverance that we can experience this rebirth. A rising trend of stylistic and artful prostheses are appearing in virtually every medium we have available today. Whether it be a music video, movie, video game or magazine, our culture and many others embrace the art of Kintsugi, no longer leaving behind or hiding imperfections, but embracing them for what they have truly become, feats of will.

Finding LIM Innovations

Everyone I’ve met at LIM Innovations exudes inspiration, innovation and determination. It’s a truly momentous thing when people like that come together to improve the lives of other people. To witness a modern day virtue of a humanitarian effort with the driving force of today’s rapidly changing world of technology and opportunity is nothing short of grand.

I found LIM while I was a student lost in the mire of being alone in my dreams. I pushed myself out into an Orthotics and Prosthetics conference in the Bay Area to illuminate my path. At this conference I would hold in my hands the Infinite Socket, which would illuminate everything.

As a son of a below-knee amputee and volunteer of Shriner’s Hospital for Children, I know the issues that come with a new lower limb prosthetic socket. I know and feel a fraction the frustration my Father had when he was waiting ever so long for a conventional socket. My Father is a man who leapt straight back into a several story building of work in a wheelchair mere months after his amputation. Every commute was done with one leg, among many other imaginable hardships. When it finally came time to visit the Prosthetist to try on his new socket, we were both frothing at the mouth in excitement. The moment he donned his prosthesis, his expression was priceless. He was the happiest he could be and I was stricken with a wash of relief. Although, sadly the day he was waiting for left him leaving the clinic without a socket, due to a problem with the fit. He was told to come back in another week, after already waiting several weeks.

When I held the Infinite Socket, I imagined a world where my Father’s first interaction with his new leg was unfettered from the inconvenience of a static old idea. An old idea where a person’s body stays the same shape at all times. An old idea that doesn’t flow with the ever changing beauty of the human anatomy. In my hand I was holding a compliment to such a beauty. The sleek black interface issued a simple design that fits nicely into the aesthetics of a computerized knee. Finally, a socket that matches the current innovations of prosthetic technology.

I would soon become very familiar with the Infinite Socket’s framework after meeting up with LIM’s gracious founders who let me, a lost unknown student come in and have a look around. That look around turned into a job where I worked with the production team on the front lines preparing sleek and strong carbon-fiber struts, plump and comfortable ischial seats, and distal cups that would make any residual limb feel right at home.

LIM Innovations represents a part of the human effort to make the world a better place.

ABC 7: Bay Area Company Creates for Amputees

abc

ABC 7 News visited the LIM Innovations headquarters last Thursday for a behind-the-scenes look at how the Infinite Socket impacts amputees. Jonathan Bloom of ABC7 spent two hours with the production team, the two co-founders, and an above-knee amputee using the socket. He cut the video from his truck, and the segment went live on the 6 o’clock news that night. If you missed it, check out the full story.

Kaiser Amputee Clinic

During our trip to San Diego, we visited with Dr. Michael Jaffe from Kaiser Permanente. He invited us to an amputee clinic, where he and four prosthetists offered consultation to a variety of patients. In the clinic were a number of amputees, new and old, who shared their experience and received expert advice. The group spent ten minutes with each patient, leaving them with a clear direction for next steps in care. LIM Innovations was fortunate to sit in on the event, learn from a group of clinicians, and share the Infinite Socket with interested amputees.

Dr. Jaffe was happy to involve us, and submitted a short note about the clinic:

My buddy Bruce Bekkar, MD, gave me the email of a guy named Andre whom he had met at a TED talk.  Andre is working for a startup company who manufactures prosthetic limbs for above-the-knee amputees (AK).  I invited Andre to come to my monthly Amputee Clinic. It turned out to be quite the fortuitous encounter.

Our first patient was a 22 year old man who lost his left leg above the knee four weeks ago in a motor vehicle accident.  He came into our clinic clearly distraught, scared, and I could sense a feeling of hopelessness, and his parents even more so.

I asked the patient to wait until the end of the clinic to watch a demonstration put on by Andre’s team, Lim Innovations.  As the patient rolled back into the clinic an hour and a half later he was met by two Infinite Socket users, both in their 20s and both AK amputees, with the latest in Stance-phase control (electronic) prosthetics with the new Lim suspension socket-the innovative design of which I had never seen before. These guys where fit and happy, one of them is a professional model and the other is training for the Paralympics.

You could see the vail of confusion and sadness lift as the 22 year old amputee sat in a circle along with me and six prosthetists all asking clinical questions of LIM CEO.  The patient even joined in with his own clinically relevant questions.

At the end of the presentation the new amputee announced he wanted to be a Beta tester for the new socket.  When the clinic was over the new amputee shook my hand, looking me in the eye and stated, “I am very excited, and when can I get started?”

CNC Machines and Prosthetics

I came to LIM wanting to learn.  After this last year, I learned so much about prosthetic and even more about CNC machines, and so began my dreams of machines and their code.

My role at LIM is to fabricate many of the custom parts for our prosthetic sockets. We are constantly developing new ideas to implement on existing and future designs. Currently, we employ the use of 3D printers, CNC laser cutters, water jet, and a CNC milling machine. CNC stands for Computer Numerical Control.

Once a part has been designed into a 3D model, it is defined into code for the machine you plan on using. A computer is connected to a machine to automate and repeatedly execute parts precisely. Each machine uses specific materials and has its own set of capabilities.

My personal love is the CNC Tormach Milling Machine. It cuts plastic, aluminum, steel, and titanium all with the right specs. I have spent extensive time with this machine, cutting metal into presses or simple components. Its 3-axis system can cut in three dimensions across the X, Y, and Z plane. This machine trumps other machines at making 3D contoured shapes. Depending on how you orient the part, cutting bits, and other inputs, it can cut organic shapes in blocks of material. This is particularly important when making molds or trying to mimic biology.

Our aluminum distal plates are made entirely on the CNC Tormach Milling Machine. Depending on the amputation type, each of our plates allow different, yet accurate, adduction angles. The distal plate’s interface connects distal components, including knees and feet, by simply mounting one piece.

Many of these machines are integrated into the fabrication of our socket, but we are always looking for new or different ways to make parts. LIM excels at understanding existing machines with new materials and applying it to a better prosthetic socket.

Kendrick Coburn, Prototyping and Production Engineer, picks up the pen this week to share his love for CNC Machines and how he uses them to create components for the Infinite Socket.

How the Infinite Socket is like an iPhone

At LIM Innovations, we strive to defy convention.  Our Infinite Socket embodies this intention in a couple major ways: By design and model.

Conventional prosthetic sockets have forever been a fixed rigid shape.  They contain a finite volume and for most intensive purposes, the alignment is inherently built into them.  Conventional sockets are like a work of art, a one-time snapshot of an object that interacts with a residual limb.

The problem? A residual limb is anything but fixed and rigid.  Short-term and long-term volume fluctuations like temperature changes, eating a meal containing a high sodium level, undergoing dialysis and seasonal changes (like the upcoming Holiday Season) are a few examples that can leave the user in a constant battle to maintain the appropriate fit.

This is one of the many reasons why we designed the Infinite Socket to be dynamic and flexible: to give the user the ability to tackle their volume fluctuations in a simple, user-friendly way without sacrificing control of their prosthesis.

The analogy I like to use is wearing a conventional socket is like wearing a clog versus wearing the Infinite Socket is like a high-performance running shoe.  It’s designed to work with the residual limb, not against it; a concept we like to call the Dynamic Motion Frame.

So what about the Model?  An iPhone is composed of the phone itself (the hardware) as well as an operating system and apps (the software) that together constitute the platform and create the user’s experience.  We feel the modularity of Infinite Socket is a platform.  The Base Plate and Struts are ‘hardware’ and the Distal Cup, the 3D printed Ischial Seat and the Brim are the ‘software’.  Just as operating systems and apps are updated, so is our software.   Our Innovations Team uses User Generated Innovation (UGI) to drive our software updates and we have many planned throughout 2015.

As we release new brims, suspension methods, and new ischial seat designs, the user can update them with their LIM Clinician. Rather than undergo a lengthy conventional socket replacement (weeks of appointments and high costs) the user can simply swap out one of the many modular components for an updated version in one quick visit.

Empowering our users requires thinking unconventionally and unconventional thinking allows the Infinite Socket to create Infinite possibilities.

Here at LIM Innovations we pride ourselves on the diversity of our team. We have a fantastic group of engineers, designers, machinists, clinicians, and amputees with relevant experience in the field. With such a diverse group working behind the scenes, we invite you to join one of our staff members each week for an in-depth look at what they bring to table. It is our goal to provide our loyal readers a behind-the-scenes look at LIM Innovations. Clinical Director, Jon Smith, picked up the pen this week to share how the Infinite Socket is similar to the iPhone and provides users with a dynamic system for their residual limb.
