Abstract: A prosthetic system includes a pump mechanism operatively connectable to a prosthetic foot. The pump mechanism has a housing defining first and second ports, a membrane having an outer edge portion secured to the housing, and a fluid chamber with a volume defined between the housing and a first side of the membrane. The fluid chamber is in fluid communication with the first and second ports. A connector is attached to a second side of the membrane opposite the first side. The connector operatively connects the membrane to the prosthetic foot such that when no weight is placed on the prosthetic foot the volume of the fluid chamber is zero or near-zero and when weight of a user is placed on the prosthetic foot the membrane deforms to expand the volume of the fluid chamber.

Abstract: A prosthetic joint can include a first attachment member and a second attachment member coupled to the first attachment member. The second attachment member can include a cylindrical chamber. The prosthetic joint can include a fixation system disposed within the cylindrical chamber comprising at least one cam. The prosthetic joint can have an unlocked configuration, wherein in the unlocked configuration the first attachment member and the second attachment member can rotate relative to each other. The prosthetic joint can have a locked configuration, wherein in the locked configuration the first attachment member is substantially prevented from rotating relative to the second attachment member.

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: An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.

Abstract: A vacuum suspension system includes a rigid socket defining a socket wall having exterior and interior surfaces. The socket defines an aperture extending between the exterior and interior surfaces, and has a closed distal end and an open proximal end with an interior cavity defined by the interior surface. A fluid regulator is provided at the aperture and operatively engages the fluid regulator. A pump system includes a pump and a covering for securing over the exterior surface of the socket and carrying the pump. The pump is configured for placement proximate to the fluid regulator and arranged for drawing air from the socket through the aperture. A chamber having a variable volume is formed by a space defined between the exterior surface and an inner surface of the covering proximate to the pump.

Abstract: A device for damping jerks in a rope (2) comprises a ring (3) made of a resilient material, into the hole (4) of which a loop (2a) of the rope is to be introduced in order to be arranged on the ring in such manner that the ring is elastically deformed when a pulling force is exerted on the rope. The ring (3) has a projection (5), which is formed in one piece with the ring and protrudes from the outside of the ring. The projection is arranged to hook the rope loop introduced into the hole (4) of the ring onto its portion closest to the ring (3) to cause a turning-inside-out-like, elastic deformation of the ring (3) when a pulling force is exerted on the rope (2).
