Abstract

A breast prosthesis implant is disclosed comprising a generally conical bio-compatible fabric shell. The shell is pervious to tissue growth and body fluids. The interior of the shell is divided into series of discrete chambers separated by pervious fabric dividers, the chambers containing masses of bio-compatible fibers. The fiber concentration in the chambers nearest the apex of the cone is less than the concentration in chambers progressively further from the cone apex. Preferably, the shell is somewhat stretchable to permit the volume of the shell to increase or decrease in accordance with the weight gain or loss of the patient.

Claims

1. A breast prosthesis implant comprising a bio-compatible tissue and body fluid pervious fabric shell in the general configuration of a cone, a plurality of pervious partitions extending transversely within said shell and dividing said shell into a series of chambers, and bio-compatible fibrous masses disposed within said chambers.

2. A prosthesis in accordance with claim 1 wherein the density of said fibrous masses increases progressively from the chamber closest to the apex of the cone to the chamber most remote from the apex of the cone.

3. A prosthesis in accordance with claim 1 wherein said shell includes a velour outer surface portion.

4. A prosthesis in accordance with claim 1 wherein said shell and fibrous masses are comprised of a homopolymer polyester material.

5. A prosthesis in accordance with claim 1 wherein said shell comprises a woven fabric including on the external surface thereof loops.

6. A prosthesis in accordance with claim 1 wherein said partitions are comprised of open weave fabric.

7. A prosthesis in accordance with claim 1 wherein said shell comprises a stretchable knitted fabric whereby the same may increase and decrease in volume.

8. A prosthesis in accordance with claim 7 wherein said partitions are woven fabric and are less stretchable than the fabric of said shell, whereby said prosthesis is susceptible to greater growth in the direction of the axis of said cone than in a radial direction.

9. A prosthesis in accordance with claim 8 and including at least two said partitions dividing the interior of said prosthesis into at least three said chambers, the concentration of said fibrous masses increasing progressively in the chambers more remote from the apex of said shell.
