A prosthetic liner includes a flexible elongate, generally conical body portion formed from an elastomeric material. The body portion defines an inner surface, an outer surface forming a liner profile between a distal end and a proximal end, and an axis extending between the distal and proximal ends. At least one seal element extends circumferentially about the axis and protrudes radially outward a distance from the liner profile. The at least one seal element has a seal height defined between the liner profile and a radially outward end of the at least one seal element. The seal height varies circumferentially about the axis between a first seal height and a second seal height.

A suspension liner for a residual limb has a liner body with a plurality of anterior and posterior projections formed from a thickness of the liner body. Medial and lateral tendons are located between and correspond to profiles of the plurality of the anterior and posterior projections such that the medial and lateral tendons are located on opposed sides of the liner body relative to one another. The medial and lateral tendons flare circumferentially toward proximal and distal sections of the liner body.

A liner to an appendage of a user includes a base member, a bracket adjustably mounted to the base member to a desired height position, and a plurality of arms pivotably mounted to the bracket. Each arm can include a rotating member, such as a roller ball, coupled to a top end of the arm. The plurality of arms can extend from the bracket in a generally upright position and can support the liner thereon in an inside out position so that the application of downward pressure by the appendage of the user within the plurality of arms permits the arms to pivot outward, thereby allowing the plurality of arms and roller balls to slide the liner around the appendage of the user.

Prosthetic socket sealing systems and methods of use. Embodiments of the present invention include various combinations of sealing elements that are associated with a rigid prosthetic socket and act to seal the socket interior against air intrusion or escape via the open proximal end thereof. The socket interior may thus be evacuated for purposes of vacuum suspension or otherwise.

Prosthetic liners, prosthetic sockets and prosthetic suspension sleeves, as well as orthotic components, having enhanced thermally conductivity and/or enhanced heat absorption capabilities. Such components may be used in various combinations to create assemblies and systems that are operative to better transfer heat away from and/or absorb heat produced by residual or intact limbs of a user.

A sleeve for mounting a prosthetic unit on a limb is formed in a knitted fabric comprising elastic yarns to allow circumferential extension of the sleeve to grip the limb. Adherent fibres are integrated within the fabric and exposed on the internal surface of the sleeve to provide additional grip. Such fibres can be silicone or silicone based yarns. An end of the sleeve is adapted to couple with a prosthetic unit. The knitted fabric may include yarns of restricted elasticity to limit longitudinal extension of the sleeve, and the elastic yarns and the yarns of restricted elasticity are typically located in discrete sections (2, 4, 6) of the sleeve. Such discrete sections will normally extend longitudinally in the sleeve. The knitted yarns at the end of the sleeve are normally bonded directly to a coupling element (8, 10, 12) for attachment to a prosthetic unit.

Linings for fitting an object to a body part, and their use, are provided. The lining may include a flexible sheet having a fluid impenetrable outer portion enclosing an internal volume and the lining may include barriers forming a number of compartments substantially secured in place within the internal volume. The barriers may be permeable to gas and/or liquid, yet may be impermeable to the conformable material and the gas and/or liquid may be supplied to or aspirated from one or more compartments within the internal volume. Aspiration of gas and/or liquid from the internal volume may limit both deformation of the conformable material and shape adjustment of the flexible sheet.

The invention is a 3D printed prosthetic socket for a residual limb consisting of a 3D printed shell. The 3D printed prosthetic socket comprises a distal end adapted for linking the interconnecting adapter of the socket and a proximal end with an opening adapted for inserting the limb. The 3D printed shell comprises a first housing of the socket comprising an inner wall and an outer wall, wherein the first housing of the socket comprises a rigid region having, in the direction perpendicular to the inner wall, the rigidity of the rigid region and an elastic region having, in the direction perpendicular to the inner wall the rigidity of the elastic region. The rigidity of the elastic region is smaller than the rigidity of the rigid region, wherein the elastic region comprises a set of shaped openings and is adapted for softening the contact of the residual lower limb with the prosthetic socket, wherein the 3D printed shell is made of a single 3D printed part.

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.

A knitted-fabric part including a basic part knitted with at least one knitted-fabric thread, and at least one extension part attached to the basic part to form a contiguous and intact structure. At least one unravelable connecting thread attaches the basic part to the at least one extension part, such that removal of the at least one unravelable connecting thread separates the basic part from the at least one extension part.
