A prosthetic device includes a flexible interface configured to conform to a residual limb of a user, a prosthetic socket including an outer shell more rigid than the flexible interface and positioned external to at least a portion of the flexible interface, and one or more vibrational devices placed in connection with the flexible interface to impart vibration to the residual limb.

A prosthetic liner for application on a stump, the prosthetic liner including an elastic base, which has a proximal opening for insertion of the stump a receiving space, and a distal end. At least one pneumatic piston is arranged on the outer face of the prosthetic liner.

The attachment plate for a prosthetic socket is fabricated into the distal end of a prosthetic socket. The attachment plate comprises a body with a peripheral seal, a valve, an air tunnel, and an exhaust port. When fastened in the distal end of a prosthetic socket, the peripheral seal creates a secure seal to the inner wall of the prosthetic socket and the exhaust port remains exposed to atmosphere. The valve is open to the cavity of the prosthetic socket for air to be removed to secure a prosthetic via vacuum or suction. Air from the cavity moves through the valve, through an air tunnel machined into the cylindrical body, and is expelled out of the exhaust port.

A prosthetic socket for a residual limb of the lower extremity or upper extremity of an individual person is provided. 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 appropriate for the individual. The prosthetic socket may be an assembly 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.

A vacuum suspension system includes a pump mechanism operatively connectable to a prosthetic socket. The pump mechanism has a first member and a second member. An inflatable bladder is disposed between the first and second members. A fluid chamber is located between the first and second members and fluidly separate from the inflatable bladder. Inflation of the inflatable bladder mechanically separates the first and second parts to create a vacuum pressure in the fluid chamber.
