Abstract
A prosthetic system includes a prosthetic foot with a foot member defining a first end portion, a second end portion, and an intermediate portion defining a curvature and extending between the first and second end portions. A pump mechanism is coupled to the foot member. The pump mechanism includes a housing defining a cavity, and a membrane situated in the cavity. The pump mechanism is movable between an original configuration and an expanded configuration. A movable member includes a first portion coupled to the membrane and a second portion arranged to slidably engage the foot member. Relative movement between the first and second end portions moves the first portion of the movable member relative to the housing and slides the second portion along a length of the foot member to shift the pump mechanism between the original and expanded configurations.
