1. A prosthetic device for attachment to a residual limb, the prosthetic device comprising:
- a socket-forming member configured to receive the residual limb;
a first portion;
a second portion operatively connected to the first portion and rotatably movable relative to the first portion; and
a pump attached to the first portion and adapted to draw a negative pressure within the socket-forming member upon rotating movement of the second portion relative to the first portion, wherein the pump includes an actuator operatively associated with the second portion such that the second portion acts on the actuator to effect drawing of the negative pressure by the pump upon selected rotational movement of the second portion relative to the first portion.
