Abstract
An artificial limb using a vacuum attachment principle is provided with an electrically activated pump that may be readily incorporated into the artificial limb or into a separate portable device. Because the electrically activated pump does not require manual manipulation to create vacuum, it is substantially easier to use than a manual pump. Due to the small size and small battery required by the electrically activated pump disclosed here, it may be readily incorporated into a prosthesis.
