Abstract: 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. First and second fluid chambers are located between the first and second members. The second fluid chamber is fluidly separate from the first fluid chamber, and arranged for fluid communication with the socket. An increase in volume of the first fluid chamber mechanically expands the second fluid chamber, which, in turn, creates a vacuum pressure in the second fluid chamber.

Abstract: A lever-actuated distal lock connects a limb liner to a prosthetic leg or arm hard socket. In some versions, air-sealing capability may limit/prevent air flow through the distal lock, even with vacuum inside the socket. To unlatch the lock, a lever is swung to pull a sliding shaft outward in the lock housing. Swung in the opposite direction, the lever releases the sliding shaft to be biased to a latched position wherein slanted surfaces of the shaft inner end and a liner pin cooperate to allow the pin to slide down into, but not up out of, the lock. In some versions, the shaft inner end slides relative to, but is biased away from, the shaft opposite end, so that the inner end moves out of the way of the downwardly-sliding pin, without moving the entire lock shaft and without disrupting the optional air seal.

Abstract: A flexible distal cup for use as part of a modular prosthetic socket for a residual limb may have a substantially closed distal end, an open proximal end, an inner surface and an outer surface. The flexible distal cup is configured to reside within an outer support structure of the prosthetic socket and to receive a distal portion of the residual limb. In some embodiments, the flexible distal cup may be made of a composite polymer composition, including an ethylene-vinyl acetate (EVA) copolymer and polycaprolactone (PCL). The EVA copolymer may be between about 45% and about 55% of the composite polymer composition by weight, the vinyl acetate of the EVA copolymer may be less than about 25% of the EVA copolymer by weight, and the PCL may be between about 45% and about 55% of the composite polymer composition by weight.

Abstract: A prosthetic device, system and method is arranged to generate negative pressure inside a prosthetic socket. A pump mechanism is connected to a prosthetic foot and has a fluid chamber in fluid communication with the prosthetic socket during gait for drawing air from the prosthetic socket in step phase, and expelling air into the atmosphere in swing phase. The vacuum assisted suspension results in secure and intimate suspension as the negative pressure formed inside the prosthetic socket holds a residuum firmly to walls of the prosthetic socket. The vacuum is preferably formed at the distal area of the prosthetic socket, and sealed by a suspension liner having a seal component.

Abstract: The socket system includes a socket and a vacuum liner. A one-way valve is positioned within the closed distal end of the socket and provides controlled fluid communication between the interior socket space and an external environment. The closed distal end of the vacuum liner includes a distal portion formed of a higher durometer elastomeric material than the surrounding portions of the liner, and including a concave section extending from an external surface thereof towards the interior liner space. The socket, on the interior of the closed distal end thereof, includes a receiving portion that corresponds to and receives the distal portion of the vacuum liner (e.g. matching the perimeter and depth of the distal portion). The receiving portion includes a bottom surface (e.g. a flat surface) opposite to the concave section of the vacuum liner when received therein, and defining an exterior liner space therewith.
