According to the embodiments described herein, prosthetic devices can include a prosthetic socket, a vacuum passage, and an evacuation device. The interior of the prosthetic socket can be adapted to receive a residual limb. The vacuum passage can extend through the side wall of the prosthetic socket and into the interior of the prosthetic socket. The evacuation device can include an electrically powered vacuum pump contained within a housing. The housing can be attached to the side wall on the exterior of the prosthetic socket. The electrically powered vacuum pump can be in communication with the vacuum passage. The electrically powered vacuum pump can draw air from the interior of the prosthetic socket, while the residual limb is received within the interior of the prosthetic socket, to evacuate the prosthetic socket.
