Abstract
A silicone elastomer suspension liner for a prosthesis includes a soft inner silicone elastomer layer and a relatively harder outer silicone elastomer layer, with both layers being formulated to provide desired physical characteristics of the liner. An elasticity controlling matrix material and a prosthesis connecting element may be provided in the distal end area of the liner. The softer inner layer closely conforms to the residual limb that is to be fitted to a prosthesis while the harder outer layer provides durability and strength for the liner.
