Abstract
A visco-elastic polymer liner for use in donning over a residual limb and fitting within the socket of an artificial limb. The liner is shaped to have its cavity formed with a volume and shape less than a volume and shape of the residual limb for both tension and tissue configuration relief while the liner has an outer surface formed with a volume and shape greater than the volume and shape of the artificial limb socket for relief of certain tissue configurations and to create weight bearing, relief and compression areas on and in the liner to absorb and dissipate shock, shear and mechanical forces through the liner otherwise transmitted to the residual limb. The liner may have imbedded on its inner cavity side electrodes adjacent muscles that are sensitive to the muscle action potentials to generate signals to a power source to move an articulable artificial limb. The liner may take the shape of a tube to be donned over a paralyzed limb similarly having electrodes imbedded in its inner cavity side adjacent neuromuscular junctions which are connected to a muscle action potential generator to activate flexion and extension of the paralyzed limb. A method for making the liner is also claimed which comprises the making of a positive model of the residual limb, reducing the model, forming the liner about the reduced model and laminating a hard socket over a reduced model of the liner.
