The SmartPuck from 5280 Prosthetics is an internal vacuum system that represents a new generation of smart socket technology. The entire unit is designed to fit inside the prosthetic socket, eliminating vacuum leaks from the socket, pump, and connection components. The SmartPuck maintains a constant level of vacuum, which helps improve tissue perfusion and overall limb health. Above knee or below knee amputees can adjust the Puck with a smartphone and select a pressure setting that feels right for their limb and activity level. The SmartPuck is lightweight and requires less than 2″ of clearance.
