Abstract

A preformed, seamless, three-dimensional, anatomically contoured prosthetic device for reinforcing breast tissue and supporting a breast implant includes a flat back wall, a concave front wall and a curved transitional region between the flat back wall and the front wall defining a smoothly curved bottom periphery. A concave receiving space is defined by the back wall and the front wall for at least partially receiving and supporting the breast implant therein. The three-dimensional prosthetic device is free of wrinkles, creases, folds or seams, which may have otherwise caused potential tissue irritation, bacteria hosting, infection and palpability problems.

Claims (10)

1. A preformed, seamless, three-dimensional, anatomically contoured prosthetic device for reinforcing breast tissue and supporting a breast implant, consisting of:

a back wall, the back wall having an upper rim and a bottom portion situated opposite the upper rim; and

a front wall, the front wall having an upper edge and a bottom portion situated opposite the upper edge, the bottom portion of the front wall being joined to the bottom portion of the back wall to define a smoothly curved, seamless bottom periphery to the prosthetic device, the front wall being spaced apart from the back wall to define therebetween a receiving space for at least partially receiving and supporting a breast implant therein, wherein the back wall is substantially flat and the front wall is concave,

wherein the prosthetic device is adapted to be implanted within a breast pocket of a patient such that the back wall is positioned adjacent to the chest wall or muscles overlaying the chest wall,

wherein said prosthetic device has resiliency sufficient to independently support its own weight and to maintain its shape prior to implantation,

wherein the prosthetic device is formed of a biocompatible mesh having a substantially uniform construction throughout, and

wherein the prosthetic device is shaped using a thermal forming process.

2. A prosthetic device as defined by claim 1 , wherein the upper edge of the front wall is curved, and wherein the height of the front wall is less than the height of the back wall.

3. A prosthetic device as defined by claim 1 , wherein the back wall and the front wall are joined together to provide the prosthesis with a semi-circular, toroidal shape.

4. A prosthetic device as defined by claim 1 , wherein the front wall and the back wall are formed from a mesh material, wherein the mesh material is a thermal formable polymer.
