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.

The prosthetic device is a general use prosthetic device for shower and daily mobility applications which provides a semi-custom fit. The semi-custom fitment of the leg height and anatomical sizing of the affected leg amputation are possible via configurable liner pads which can be interchanged within the support socket based on need by the wearer. The device is capable of being used on either the left or right leg with no modifications to the device and can be secured to the wearers residual limb via a friction fit between the socket liner and limb. Furthermore, an ergonomic handle and grip provides another point of control for the device to assure safety and security.

A flexible inner socket is fabricated by forming a pre-socket. The pre-socket includes a body formed with an opening and an enclosed end. The enclosed end is opposite to the opening. The body of the pre-socket has an outer circumference that is smaller than the inner circumference of the rigid prosthetic socket. Different portions of the body may have different thicknesses. The preform socket is heated. After the heating, the flexible inner socket is formed by molding the pre-socket onto the inner surface of the rigid prosthetic socket to form the flexible inner socket. The inner circumference of the rigid prosthetic socket is reduced by a thickness of the flexible inner socket when the flexible inner socket is attached to the inner surface of the rigid prosthetic socket. An opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

A prosthetic interface includes a body portion having an open proximal end and a closed distal end including a distal cup. The body portion includes a membrane component having a flexible configuration defining an internal flow space extending along a length of the membrane component between an inner side arranged to face a skin surface of a residual limb and an outer side arranged to face away from the skin surface. At least one material coating is selectively applied to the membrane component that interacts with at least one of the membrane component and the distal cup to define at least one breathable region along the inner side that allows fluid flow between the internal flow space and the residual limb, and at least one impermeable region along the outer side that allows for vacuum suspension between the prosthetic interface and a prosthetic socket.

A multi-component frame includes a first component made from a rigid structural material and a second component connected to at least an end portion the first component. The first component is constructed from a metal or metal alloy, and the second component is constructed from a material different from the first component. The first and second components form at least part of a length of the multi-component frame.

A liner for an orthopedic or prosthetic device includes a core formed from a porous and compressible material, a first layer secured to the first side of the core and forming a first surface to the liner, and a second layer secured to the second side of the core and forming a second surface to the liner. The first and second layers may comprise different properties from one another and be formed from different materials including fabrics and polymeric materials. A polymeric film may be secured to the core or one of the layers to define at least part of a surface of the liner.

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 provides a prosthetic socket (10) having a longitudinal axis X for attachment to a limb of a patient having first and second sides (A, B) which comprises a first portion (20) having a first edge (22), a second edge (24) a first end (26) and a second end (28) and second portion (30) having a first edge (32) a second edge (34) a first end (36) and a second edge (38). A hinge (40) is connecting the first edge (22) of the first portion (20) to the first edge (32) of the second portion (30) and a clasp (50) is provided between the second edge (24) of the first portion (20) and the second edge (34) of the second portion (30). Such an arrangement allows for a prosthetic socket (10) to be more easily attached and removed to a patients limb.

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.

An adjustable prosthesis system for a residual limb includes: an adjustable outer shell having a bottom, an adjustable inner volume, and an adjustable inner shape; at least one closure component attached to the outer shell and adapted to adjust the width of the inner volume and/or inner shape; an inner liner adapted to receive the residual limb and to be inserted in the inner volume; and an adjustable connector having a proximal end adjustably connected to a distal end of the outer shell and adapted to provide concurrently for a plurality of directional adjustments and/or angular adjustments of a position of the distal end of the outer shell relative to the proximal end of the connector, a distal end of the connector adapted to connect to a prosthetic device, wherein adjustments of the width(s) and the connector provide for a custom-like fit of the prosthesis on the residual limb.
