A liner for a prosthesis, wherein the liner is made of a liner material and comprises a proximal opening for accommodating an amputation stump, a distal end, a longitudinal direction, which extends from the proximal opening to the distal end, and an auxetic material The auxetic material is a two-dimensional-auxetic material, which is arranged in such a way that an extension of the liner in the longitudinal direction leads to an expansion of a diameter of the liner.

An adjustable socket system includes a socket frame having a proximal area, a distal area opposite the proximal area, a first component arranged along a first side of the socket system, and a second component arranged along a second side of the socket system. The first component is connected to the second component. A tubular insert is arranged on an interior of at least the proximal area of the socket frame. The tubular insert forms an interior surface of the socket system. At least one tensioning element operatively connects the tubular insert to the first and/or second components. At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.

An adjustable prosthetic socket includes proximal and distal ends and an axis extending between the proximal and distal ends. A distal base is adapted to support a distal portion of a residual limb and is located at the distal end of the socket. First and second spines extend upward from the distal base that define at least part of a circumference of the socket about the axis. A proximal support is connected to the second spine and arranged to distribute pressure from the second spine over a portion of the residual limb. A tensioning system is operatively connected to the first and second spines and arranged to selectively adjust the circumference of the socket. The tensioning system includes a dial tensioner connected to the first spine.

A post-operative support apparatus for a patient's residual limb includes: a planar, stretchable and flexible wrap panel sized to wrap around an outer circumference of a patient's residual limb, along a length of the patient's residual limb, where the wrap panel includes one or more fasteners (such as hook & loop fastener components) for maintaining the wrap panel in place around the patient's residual limb; a pair of substantially rigid, elongated side support panels to respectively apply to the medial and lateral sides of the patient's residual limb, over the wrap panel; a distal cushion to apply against a distal end of the patient's residual limb; and a retainer maintaining the distal cushion against the patient's residual limb.

At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.

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 method for designing a prosthetic limb including obtaining a three-dimensional model representing a limb of a patient. One or more criteria for a prosthetic limb are determined, from the three-dimensional model. Object data is generated for one or more elements of the prosthetic limb according to the determined criteria.

An outer frame for a prosthetic limb is provided. The outer frame is formed from one or more parts and has a plurality of air flow openings.

An inner liner for a prosthetic limb is provided. The liner comprises a plurality of airflow openings.
