Abstract
A prosthetic foot including a foot member and a heel member attached to a bottom surface of the foot member. A pump mechanism is located above the foot member and includes a housing and an elastomeric member at least in part defining a fluid chamber. The elastomeric member is operatively connected to the foot member such that when no weight is placed on the prosthetic foot the volume of the fluid chamber is zero or near-zero and upon heel strike the housing rotates relative to the foot member to expand the volume of the fluid chamber and draw fluid into the fluid chamber from a prosthetic socket in fluid communication with the pump mechanism.
