Abstract
A surgically implantable breast prosthesis formed from a flexible container having a front wall and a back wall; the front wall having an outer shape approximately that of the human breast and the back wall having a shape approximately that of the chest wall. The container includes a prolongation extending angularly outwardly toward the axilla region of the anatomy and overlying the pectoral muscle. The container is filled with a silicone gel and a fabric impregnated with the same material used to form the container is secured to the back wall to increase the rigidity of the back wall. A strip of Dacron felt is secured to the outer periphery of the back wall around the axilla prolongation and a small portion of the back wall of the container to support the prosthesis by tissue ingrowth into the Dacron felt.
