Abstract

The mammary prostheses (10) of the invention have a self-sealing area (15) in the upper pole region of the anterior face. The self-sealing area (15) is greater than that of a traditional filling port, and reduces the severity of the consequences of an inadvertent puncture by a hypodermic needle during the filling process. Also, this self-sealing area (15) is thicker than the material in the other areas of the prosthesis, causing fluid introduced to the prosthesis to stay in the lower pole region of the prosthesis, making the shape of the prosthesis appear more like that of a natural breast.

Claims (17)

1. A mammary tissue expander comprising a shell having an anterior face and a posterior face, the anterior face having an upper pole portion and lower pole portion meeting at an apex, the prosthesis comprising a self-sealing material bonded to the shell within the upper pole of the anterior face of the shell to create a self-sealing region of the expander that is self-sealing after needle puncture.
2. The tissue expander of claim one further comprising an injection port located within the self-sealing region of the expander.
3. The tissue expander of claim 1 where the self-sealing material bonded to the shell acts to permit controlled directional expansion of the expander.
4. The tissue expander of claim 1 wherein the self-sealing material is a unitary body comprising at least one layer of fabric and at least one layer of elastomeric material impregnated with a swelling agent, the fabric restraining expansion of the elastomeric material.
5. The tissue expander of claim 1 wherein at least a portion of the outer surface of the shell is textured.
6. The tissue expander of claim 1 wherein the shell comprises silicone.
7. The tissue expander of claim 4 wherein the fabric is a knitted fabric.
8. The tissue expander of claim 4 wherein the fabric is a woven fabric.
9. The tissue expander of claim 4 wherein the fabric is a non-woven or spunbonded fabric.
10. The tissue expander of claim 4 wherein the fabric is a crocheted fabric.
11. The tissue expander of claim 4 wherein the fabric is a polyester fabric.~
12. The tissue expander of claim 4 wherein the swelling agent is dimethylpolysiloxane.
13. The tissue expander of claim 4 wherein the self-sealing material comprises at least two layers of fabric and at least two layers of elastomeric material.
14. The tissue expander of claim 4 wherein the self-sealing material comprises at least two layers of fabric and at least three layers of elastomeric material.
15. An improved method for introducing a swelling agent into an assembly comprising at least one layer of fabric and at least one layer of elastomeric material, the method comprising:
a) providing an assembly comprising at least one layer of fabric bonded to at least one layer of elastomeric material;
b) immersing the assembly in a swelling agent under conditions of reduced atmospheric pressure for a time sufficient to allow the swelling agent to enter the at least a portion of the elastomeric material.
16. The method of claim 15 wherein the elastomeric material is silicone.
17. The method of claim 15 wherein the swelling agent is dimethylpolysiloxane.
