Abstract
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 to one of the layers to define at least part of a surface of the liner.

A liner for an orthopedic or prosthetic device, comprising:
- a core formed from a porous and compressible material, the core having first and second sides;
- a first layer secured to the first side of the core and having breathable properties;
- a second layer connected to the second side of the core, the second layer formed from a hook-receivable material;
- a polymeric film having a thickness thinner than the core and the second layer, and bonded to the second layer to prevent separation therefrom, the polymeric film being breathable and porous, and forms at least one island whereat the second layer is exposed and the polymeric film surrounds the at least one island;
- wherein the first layer and the polymeric film are secured and compressed to one another about a periphery of the liner, and the polymeric film is sized only to an adjacent surface of the second layer;
- wherein the polymeric film has a gauge in the range of 0.050 to 0.5 mm, and weight of about 90 g/m^2.
A liner for an orthopedic or prosthetic device, comprising:
- a core formed from a porous and compressible material, the core having first and second sides and a periphery;
- a first layer secured to the first side of the core and forming a first surface to the liner;
- a polymeric film having a thickness substantially thinner than the core and the first layer, and being breathable and porous, the polymeric film bonded to the second side of the core to prevent separation therefrom, and defining at least part of a second surface opposite the first surface of the liner, and the polymeric film having a contrasting color relative to a color of the first layer;
- wherein the first layer and the polymeric film are secured to one another and form a tapered lip about a periphery of the liner, and the polymeric film is sized only to an adjacent surface of the core;
- wherein the polymeric film has a gauge in the range of 0.050 to 0.5 mm, and weight of about 90 g/m^2.
A liner comprising:
- a core formed from a porous and compressible open-celled foam, the core having first and second sides;
- a first layer secured to the first side of the core and having breathable properties;
- a second layer connected to the second side of the core, the second layer formed from a hook-receivable material;
- and
- a polymeric film having a thickness thinner than the core and the second layer, and bonded to the second layer to prevent separation therefrom, the polymeric film being breathable and porous, and forms at least one island whereat the second layer is exposed and the polymeric film surrounds the at least one island;
- wherein the first layer and the polymeric film are secured to one another and form a tapered lip about a periphery of the liner, and the polymeric film is sized only to an adjacent surface of the first layer;
- wherein the polymeric film has a gauge in the range of 0.050 to 0.5 mm, and weight of about 90 g/m^2.
