An adjustable seal system includes a suspension liner having a liner body and an outer surface. A plurality of seal bands are located along a height of the liner body. A seal component is arranged for removably securing to the liner body. The seal component includes open upper and lower ends defining an opening therethrough and an internal surface arranged to frictionally engage at least one of the seal bands and secure on the outer surface of the liner. The seal component also includes an upper portion descending to at least one seal, and a lower portion.

A vacuum assisted suspension system includes a prosthetic foot and a pump mechanism connected to the foot and fluidly couplable to a prosthetic socket. The pump mechanism includes an elongate pivoting member rotatable relative to the prosthetic foot about a joint and including a distal recess. A piston is connected to the foot and is movably received in the recess. A fluid chamber is defined between the piston and the interior of the recess. When no weight is placed on the foot a volume of the fluid chamber is zero or near-zero and when weight of a user is placed on the prosthetic foot the pivoting member rotates away from the piston and expands the volume of the fluid chamber to draw fluid into the fluid chamber from the prosthetic socket.

Vacuum assisted suspension system

A prosthetic system includes a liner adapted to receive a residual limb and including an outer surface defining an outlet, and a socket including an interior surface and including an aperture extending from the interior surface to an external atmosphere. A first sealed volume is defined between a first portion of the outer surface of the liner and a first portion of the interior surface of the socket. A second sealed volume is defined between a second portion of the outer surface of the liner and a second portion of the interior surface of the socket. The first sealed volume is fluidly connected to the outer of the liner, fluidly separated from the second sealed volume by a seal element, and is independent from the second sealed volume throughout use of the system.

Prosthetic system for sweat management

A brim attachment for a prosthetic socket includes a cuff section defining an upper portion of the brim attachment and is arranged to extend about and upwardly from a socket opening. The cuff section is configured to move between tensioned and relaxed positions, wherein the tensioned position the cuff section is arranged to fold away from the socket opening, wherein the relaxed position the cuff section is arranged to extend above the socket opening and generally concentric with an outer surface of the socket. An interface section defines a lower portion of the brim attachment and is arranged to extend along a surface of the socket. The brim attachment may include a seal element protruding toward a central axis of the socket.

A prosthetic socket system includes a socket having an inner surface defining a socket cavity. A liner is adapted to receive a residual limb and be removably positioned within the socket cavity. A substantially sealed volume is defined between at least a portion of an outer surface of the liner and a corresponding portion of the inner surface of the socket. A wicking material is positionable in the substantially sealed volume and at least one cooling fluid can be carried by the wicking material. The at least one cooling fluid is adapted to selectively boil within the substantially sealed volume such that heat from the residual limb is converted into latent heat of vaporization by the at least one cooling fluid for a cooling effect.

Prosthetic socket system

A prosthetic system includes a liner adapted to receive a residual limb and having a liner body formed from an elastomeric material. The liner body defines an outer surface and an inner surface opposite the outer surface. The inner surface includes a first part arranged to form a seal between the liner and the residual limb, and a second part of the inner surface has at least one flow channel arranged for promoting movement of fluid away from a skin surface of the residual limb. An outlet is defined in the second part and extends between the inner and outer surfaces. The at least one flow channel is defined in the elastomeric material forming the liner body and is in fluid communication with the outlet.

A vacuum assisted suspension system includes an elongate compression transfer element and a pump housing. The pump housing defines an enclosed space to receive a fluid. At least one wall of the housing and at least one movable wall define a fluid compartment and a non-fluid chamber. The at least one movable wall is connected to the compression transfer element. The compression transfer element causes the at least one movable wall of the fluid compartment to reciprocate in the fluid compartment to increase the volume of the fluid compartment in response to a compressive force on the compression transfer element and enables the at least one movable wall to decrease the volume of the fluid compartment in the absence of a compressive force.

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.

A prosthetic device is configurable between a predetermined shape configuration and a contracted configuration. The prosthetic device includes a resilient body having the predetermined shape configuration and defining a first surface and a second surface opposed to the first surface and separated by a wall thickness. An adjustment device is connected to the resilient body, and at least one elongate element engages at least one of the first and second surfaces and has a first end received by the adjustment device such that the adjustment device is arranged to regulate tension in the at least one elongate element. Tensioning of the at least one elongate element by the adjustment device urges the resilient body to collapse or compress into the contracted configuration, wherein release of tension of the at least one elongate element allows the resilient body to revert to the predetermined shape configuration.

Adjustable prosthetic device

A prosthetic ankle module allows for translational and/or rotational movement of a prosthetic foot relative to an adapter. The ankle module can include a four-bar linkage assembly. Links of the linkage assembly can be arranged in various configurations, e.g., parallel or non-parallel and having equal or non-equal lengths, to provide different functions and benefits, e.g., dorsiflexion, plantar flexion, vertical shock absorption, inversion, eversion, and/or rotation about the sagittal axis. Other types of linkage assemblies are also possible. A prosthetic foot can further include a support spring to limit the range of motion of the adapter in use.
