An adjustable socket system includes a plurality of shell components and longitudinal supports connected to a base and is movable between an open configuration to loosen the fit of the adjustable socket system, and a closed configuration to secure the fit of the adjustable socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point and to the shell components via a control point. Rotation of the handle displaces the movable connection point and the tensioning element relative to the control point to move the adjustable socket system to the closed configuration.

Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.

The invention provides for an improved disarticulated compression socket configured to secure a residual limb. The disarticulated compression socket may include a rigid socket frame, and preferably a 3-D printed socket having one or more surface channels that may secure a compression cord optionally positioned within a cord cylinder. Such compression cord may be responsive to a compression actuator and one or more disarticulated compression inserts such that activation of the compression actuator causes the retraction of the compression cord initiating the coordinated inward compression of each of said disarticulated compression inserts securing the residual limb within said socket frame.

A prosthetic liner for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an outer textile with variable stretch characteristics due to the knit construction and stitching and an interior gel layer. The distal region of the liner textile has less stretch than does the intermediate region or proximal region and is stitched together to form a unitary liner. The liner advantageously minimizes a condition referred to as “pistoning” wherein the distal most portion of the residual limb ascends and descends in the lower portion of the socket creating an unhealthy condition for the residual limb.

A prosthetic liner has a ventilated structure communicating with an interior volume to an exterior of the prosthetic liner, thereby permitting a transfer of air and moisture therebetween. The prosthetic liner includes a facing layer defining a periphery of at least part of the interior volume of the liner, and forming a plurality of apertures extending therethrough. A cushion layer is juxtaposed to the facing layer and forms a lattice structure including a plurality of interstices in communication with the apertures of the facing layer.

The present invention relates to absorbent articles for solving the problem of stopping the excessive accumulations of sweat from building up inside a prosthetic liner. The four layers of materials include: a first layer of a cellulose pulp material having a thickness use for a desired absorbency, a second layer of a wicking cloth material having a thickness use for a desired absorbency, a third layer of a non-toxic double side adhesive tape material one side will stick to both layer, and a fourth layer that is the opposite side which are cover with paper material that can be peeled from the third layer to adhere the inside of a prosthetic liner base sheet to stop the excessive accumulation build-up of sweating.

A liner system for reducing motion of a skeletal structure within a limb is described. The liner system includes a liner adapted to be worn over the limb and one or more shims adapted to be pre-placed along a length of the skeletal structure of the limb prior to donning the liner on the limb. The one or more shims each have a durometer, a radial thickness, a width, and a longitudinal dimension configured to compress a target area of soft tissue against the skeletal structure such that motion of the skeletal structure towards a wall of the shim is reduced.

A moisture permeable composite material for a wide variety of applications including without limitation prosthetic liners, orthotic liners, clothing, space suits and environmental suits comprising: an inner layer comprising a hydrogel, a thin tough hydrogel membrane, or dual network hydrogel; and an outer layer comprising a porous elastomer or an open cell foam.

A prosthetic socket, comprising a base for distal connection means for attaching a prosthesis component to the prosthetic socket and comprising at least one side wall, which extends from the base in the proximal direction and at least partially extends around a stump to be held in the prosthetic socket, and at least one support for fastening the side wall to the base being arranged on the base.

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.
