Title: PUMP SYSTEM
Abstract:
A prosthetic system (1) includes first and second parts (7, 9) rotatable relative to one another about a joint (16). The first and second parts (7, 9) are adapted to form at least part of a weight bearing connection (2) between a prosthetic foot (4) and a socket (6). A pump system (3) includes a pump mechanism (5) operatively connected to the first and second parts (7, 9). Rotation of the first part (7) and/or the second part (9) about the joint (16) moves the pump mechanism (5) between an original configuration in which the volume of a fluid chamber (29) defined by the pump mechanism (5) is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber (29) is increased.
