Over half of all below-knee amputees deal with sores due to an ill-fitting prosthetic socket, the deep cup that holds the limb and connects it to the rest of the prosthesis. Current sockets are bulky, complicated and rely on frequent manual adjustments based on feel. These factors lead to socket over-tightening, pain, and wound formation. Vessl aims to design an automatically adjusting prosthetic socket to free amputees from socket adjustments. The scope of this research project includes validating design ideas with amputees, determining optimal manufacturing methods, studying the Vessl socket’s strength and evaluating socket fit and patient comfort. This project is expected to 1) support Vessl’s product development, and 2) provide Vessl with strong research data on product manufacturing, safety, functionality, and user satisfaction.
