iFIT Prosthetics, LLC ? was started to address the many shortcomings in conventionally fabricated prosthetic sockets. What continually struck Dr. Dillingham was the amount of time and effort invested into trying to make a hard socket fit a changing and compressible limb. He and his team developed an adjustable prosthesis that could be fit and aligned in a single clinic visit, and mass-produced using high strength injection molded polymer materials for high quality and consistency at more affordable prices.

THE CURRENT STATE OF PROSTHETIC FABRICATION
Conventional manufacture of prosthetic devices is time consuming and labor intensive and results in a hard socket. Fabrication often requires three or more visits to the prosthetist with multiple steps in the fabrication process. It is a labor intensive process requiring multple visits to create a single prosthetic socket.

Contemporary 3D printing of digitized residual limbs at central fabrication centers has automated this process. However, these 3D sockets are hard and non-adjustable and they do not account for tissue compressibility. iFIT sockets are priced at about one-fourth of the cost of conventional transtibial and transfemoral sockets.

MARKETS FOR THIS PRODUCT
iFIT Prosthetics was started with the vision of a “prosthesis in a bag”. Our self-contained prosthetic system is easily transported to impoverished nations or war torn countries and fit by healthcare professionals with some training regarding our device. We currently work with a physical therapist and prosthetist in Jamaica who fits patients with the iFIT device. The socket is very rugged and waterproof and has demonstrated that it holds up to very demanding use.

The United States market for this system is quite large and includes persons who experience volume changes in their residual limb shortly after amputation or because of heart and renal diseases. Children and adolescents with limb loss can benefit from the adjustability of the socket which accommodates growth.

ENGINEERING EXCELLENCE AND CLINICAL EXPERTISE
iFIT Prosthetics is fortunate to collaborate with an engineering firm in Wisconsin with considerable expertise—Advanced Design Concepts (ADC) Engineering, in Pewaukee, WI. ADC has worked with iFIT Prosthetics for over 9 years and brings a very important set of capabilities. ADC has worked with many fortune 500 companies to bring a design into a fully developed product in an efficient, costeffective manner.

These devices are clinically tested at the University of Pennsylvania in the Department of Physical Medicine and Rehabilitation (PM&R) biomechanics laboratory. These sockets are well received by persons with limb loss and we have produced several scientific studies analyzing the device.

The iFIT device gently and comfortably reshapes the residual limb.
