Pediatric patients have been as poorly served by inadequate prosthetic sockets as adults. LIM Innovations adult above-knee prosthetic socket is new in terms of structure, use of thermoplastic- fiber composite materials, custom-fit, and adjustability. It delivers a highly individualized fit via a mass customization approach. It is intended to leverage lessons learned in design, engineering, and patient needs toward the fast-track development of a pediatric socket. NCC-PDI hired a design engineer, assisted with submission of an NIH SBIR application.
