Methods of fabricating a liner for reducing motion between a socket and a skeletal structure in a body part are described. Methods include selecting a plurality of compression areas, lying the compression areas along the longitudinal axis of the liner, and spacing the compression areas circumferentially around the liner. The durometer, radial thickness, width, and longitudinal dimension of the compression areas are selected to compress soft tissue of the body part against the skeletal structure to reduce motion of the skeletal structure towards a wall of the socket. Methods also include selecting a plurality of attachment areas on the liner and affixing a plurality of attachment area materials to the plurality of attachment areas. The durometer, radial thickness, width, and longitudinal dimension of the attachment area materials are selected to compress soft tissue of the body part and reduce motion of the skeletal structure towards a wall of the socket.

A hydraulic system for adjusting a prosthetic limb. The hydraulic system may include an expandable pad mounted onto an interior surface of a socket of the prosthetic limb. The hydraulic system may further include a hydraulic cylinder and a plunger mechanism. The hydraulic cylinder may be filled with a hydraulic oil. The hydraulic system may be configured to expand the expandable pad by pumping the hydraulic oil from the hydraulic cylinder into the expandable pad responsive to a volume decrease of the residual limb being more than a threshold.

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 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.

A liner with at least three substantially equally spaced attachment areas arranged longitudinally from the proximal to the distal end of the liner so as to permit relief areas between attachment areas and increase the radial thickness of the liner in the area of the liner inherently or through the addition of shims or other materials at the attachment areas. The liner and shims can be selected from a kit of different shaped liners and shims. Methods for making such a liner or liners for a kit. A method for iteratively attaching shims to the liner to prevent substantial movement of a limb's skeletal structure when the liner is worn with a socket.

A method of placing a prosthetic system over a residual limb, said method comprising the steps of: providing the prosthetic system; and placing an outer shell of the prosthetic system on the residual limb having an above-knee amputation, the outer shell at least partially surrounds the residual limb, an outer side and an inner side of the outer shell on opposite sides of the residual limb, an upper edge of the outer side above a greater trochanter, the inner side below a lowest edge of an ischium without being directly below the lowest edge of the ischium.

Disclosed is a modular prosthetic socket with highly adjustable components for fit. The socket, in one embodiment, includes at least one paddle and at least one rod, wherein straps secure the socket to a residual limb. The at least one paddle and at least one rod are adjustable by way of a baseplate assembly, which allow for radial and circumferential adjustability of the attached components.

A seal component for a prosthetic liner comprises a base portion located at a distal portion of the seal component and anchored circumferentially to an exterior surface of the liner; a seal wall arranged to flexibly and movably extend relative to a body of the liner; at least two seal rings radially and outwardly extending from the seal wall; and an outwardly pitched portion at the distal end of the seal component and extends obliquely away from the base portion relative to the axis of the seal component, and an inwardly pitched portion at the proximal end of the seal component and extends obliquely toward the axis of the seal component, the at least two seal rings are located between the outwardly and inwardly pitched portions.

A two-part prosthetic socket which includes an inner socket component having an inner profile substantially complementary to a profile of a residual limb of a patient, and an outer socket component configured to releasably attach about an outer surface of the inner socket component is disclosed. The inner profile of the inner socket component may be determined from digital data output from a medical imaging scan of the residual limb, which provides a three-dimensional digital profile of the residual limb that includes information on the size and location of at least bone and bone spurs, muscle, scar tissue, and neuroma. The digital data may further include a designed operating range for the size and shape of the three-dimensional digital profile of the residual limb based on such information. The two-part prosthetic socket may be manufactured using additive manufacturing, wherein the inner socket may be formed of a flexible material and the outer socket may be formed of a rigid material.

An ankle-foot orthosis which is capable of being worn by a user in an acquatic environment which is lightweight, water-resistant, and reduces the amount of hydrodynamic drag during motion of a leg of a user when in water. The ankle-foot orthosis can be fully customizable to the needs of the user. The ankle-foot orthosis including three protective components; a shank shell, a shin plate, and a foot shell. The ankle-foot orthosis optionally including an additional protective component; a dorsal foot plate. At least one flow passage within each of the shank shell and the foot shell. The at least one flow passage providing water drainage and air ventilation, and reducing the overall weight of the shank shell and foot shell.
