Abstract
A device and method to aid in the donning and doffing of prosthetic liners. A vacuum is created between the device and the prosthetic liner in order to expand the prosthetic liner. The device and the liner can then be placed in position on a residual limb and the vacuum released to aid in donning the liner. To doff a liner, the device is placed in position over a residual limb carrying a prosthetic liner. A vacuum is created between the device and the liner to expand the liner in order to aid doffing.

- and
- a valve member provided to allow the selective formation and removal of a vacuum in the inner space.
