ABSTRACT:
A breast prosthesis fabricated from silicone and characterized by an outer shell shaped region and an inner shall-shaped region wherein the inner region is profiled in the form of rings arranged concentrically around the mamilla. The rings may be formed bellows-like adapted to be pushed toward one another when pressure is exerted on the prosthesis. Annularly shaped recesses and beads may be arranged between the rings. The inner region may consist of lower density silicone gel having a firmness of lower penetration value but firmer than the outer region. Preferably, the outer region is slightly thicker above the manilla than below the manilla, and may have a third shell shaped region arranged between the outer and inner shell shaped regions. A recess can be provided in the lower part of the prosthesis to define an air cushion for permitting silent release of air from the prosthesis responsive to pressure applied against the prosthesis.
