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.

Claims

2. The prosthesis according to claim 1 including means secured to the inside of said back wall for maintaining the shape of the prosthesis.

3. The prosthesis according to claim 1 including a polyester fabric mesh impregnated with an organosiloxane copolymer secured to said back wall of said container.

4. The prosthesis according to claim 1 including a polyester fabric mesh impregnated with an organosiloxane copolymer secured to the inside surface of the back wall of said container.

5. The prosthesis according to claim 1 wherein said back wall and said front wall are formed as an integral unit having an arcuate wall around the outer periphery of said container.

6. A surgically implantable breast prosthesis comprising, a flexible container having a front wall and a back wall, said front wall having a shape approximating that of the human breast, said back wall having a shape approximating that of the chest wall, said container including an axillary prolongation, a silicone gel filling the inside of said container, and means for stiffening said back wall.

7. The prosthesis according to claim 6 wherein said stiffening means comprises a polyester fabric.

8. The prosthesis according to claim 6 wherein said stiffening means comprises a fabric mesh impregnated with an organosiloxane copolymer prior to being attached to said container.

9. The prosthesis according to claim 6 including means secured to the periphery of the back wall of said prolongation for promoting tissue ingrowth to secure the prosthesis in position.

10. The prosthesis according to claim 6 wherein said container includes a curved wall around the periphery of said container formed integral with said front wall and said back wall.

11. A surgically implantable prosthesis comprising, a flexible container molded from an organosiloxane copolymer and having an axillary prolongation, a silicone gel completely filling said container, means attached to said container for stiffening the back portion of said container, and means secured to the periphery of said prolongation for promoting tissue ingrowth.

12. The prosthesis according to claim 1 wherein said container is formed with a curved wall around the periphery.
