A prosthetic socket having a self-contained vacuum reservoir chamber includes a rigid, load-bearing inner socket member for receiving a residual limb and an outer, rigid, load-bearing wall section attached to the inner wall section in a manner providing a vacuum reservoir chamber between the inner wall and the outer wall section. The vacuum reservoir chamber communicates with the inner volume of the inner wall through a vacuum transfer port and the vacuum reservoir chamber may be evacuated via an evacuation port having an appropriate one-way check valve permitting withdrawal of air from the vacuum reservoir chamber while preventing ingress of air into the chamber. A method for making the prosthetic socket is disclosed.

A tube-sock shaped polymeric covering for wearing over an amputation stump. The covering has an open end for receiving the amputation stump and a closed end opposite the open end. The covering includes a docking means for attachment of an external device to the covering. The covering may also include one or more areas of reinforcing material that can be present in the form of a strip or rod, for example. The reinforcing material is comprised of a material that is less stretchable than the polymeric material forming the covering, and acts to reduce stretching and / or movement of the covering.

The invention relates to a prosthetic socket for a residual limb of the lower extremity or upper extremity of an individual person. The residual limb has particular dimensions and anatomical contours; the prosthetic socket has dimensions and contours that fit the dimensions and contours of the residual limb. The prosthetic socket may also fit in a manner that is biomechanically particularly appropriate for the individual. The prosthetic socket is an assembly of components from groups of components that include (a) struts arranged longitudinally with respect to the residual limb, (b) proximal brim members arranged proximally to the struts and connected thereto; and (c) distal socket members disposed at the distal base of the prosthetic socket. The socket components within these groups may be modular in that they can vary with respect to dimensions and / or contours, and yet have common connecting features that permit assembly of the components together to form the prosthetic socket.
