Abstract
A prosthetic system having a microprocessor-controlled socket evacuation device, and a method of retaining a prosthesis on the residual limb of an amputee using such an evacuation device. The evacuation device preferably includes at least an electrically powered vacuum pump and a power source. The microprocessor control allows the evacuation device to be operated in a manner that automatically adjusts the socket vacuum level to correspond to a determined activity level of a user. The microprocessor control may also limit operation of the evacuation device to certain determined portions of a user's gait cycle.
