Abstract: A prosthetic system includes a prosthetic foot with a foot member defining a first end portion, a second end portion, and an intermediate portion defining a curvature and extending between the first and second end portions. A pump mechanism is coupled to the foot member. The pump mechanism includes a housing defining a cavity, and a membrane situated in the cavity. The pump mechanism is movable between an original configuration and an expanded configuration. A movable member includes a first portion coupled to the membrane and a second portion arranged to slidably engage the foot member. Relative movement between the first and second end portions moves the first portion of the movable member relative to the housing and slides the second portion along a length of the foot member to shift the pump mechanism between the original and expanded configurations.

Abstract: An adjustable socket system includes a distal portion and proximal portion. An axis extends between the distal and proximal portions. A plurality of struts are connected to the distal portion and distributed circumferentially about the axis. The struts at least in part define a receiving volume adapted to receive a residual limb and are movable between an expanded configuration in which at least some of the struts are moved radially outward relative to the axis to loosen the fit of the adjustable system, and a closed configuration in which at least some of the struts are moved radially inward relative to the expanded configuration to tighten the fit of the adjustable socket system. A tightening system is operatively connected to the struts and arranged to differentially tighten and loosen the fit of the adjustable socket system on one or more areas of the residual limb via a single input.

Abstract: A prosthetic system includes a prosthetic valve having a valve body with a shaft defining a flow channel fluidly connectable to an interior of a socket. One or more ports in the valve body are in fluid communication with the flow channel and a membrane is positioned in the valve body. A release button associated with the membrane controls allow air flow into the socket via the one or more ports while air can flow out of the socket via the one or more ports independent of operation of the release button. A one-way valve is connected to the valve assembly that selectively permit air flow out of the socket. A valve insert is mountable on the socket and arranged to couple the valve body to the socket. The valve insert defines an opening configured to allow the shaft to extend through the valve insert and into the socket.

Abstract: A suspension liner is adapted to provide an interface between a residual limb and a prosthetic socket. The suspension liner defines an interior surface and an exterior surface forming a liner profile between a closed distal end and an open proximal end. The suspension liner defines a liner body portion formed from an elastomeric material and at least one seal protruding circumferentially about and radially outward a distance from the liner profile, which is defined at areas outside the at least one seal. The at least one seal has a distal root extending from the liner profile, a distal section projecting from the distal root and terminating at a peak defined as the outermost portion of the at least one seal, and a proximal section extending from the peak to a proximal free end arranged for deflection relative to the liner profile.

Abstract: A liner is arranged for use in prosthetic and orthopedic devices. The liner defines first and second end portions, and inner and outer surfaces. The liner includes an inner layer having a frictional component and forms at least part of the periphery of the inner liner surface. The inner layer defines a plurality of apertures. A porous element is in communication with the inner liner surface and is connected to the inner layer such that the apertures permit a transfer of air from the inner surface to the porous element. A base layer adjoins the porous element and extends between the first and second end portions of the liner.

Abstract: A prosthetic foot including a foot member and a heel member attached to a bottom surface of the foot member. A pump mechanism is located above the foot member and includes a housing and an elastomeric member at least in part defining a fluid chamber. The elastomeric member is operatively connected to the foot member such that when no weight is placed on the prosthetic foot the volume of the fluid chamber is zero or near-zero and upon heel strike the housing rotates relative to the foot member to expand the volume of the fluid chamber and draw fluid into the fluid chamber from a prosthetic socket in fluid communication with the pump mechanism.
