Abstract

Abstract A breast prosthesis to be worn on the body of a person who has had a mastectomy includes a soft-elastic prosthetic body made of two plastic sheets which are connected to each other along a common edge, with a plastic mass being contained hollow-free between the plastic sheets. The prosthetic body has a front side resembling in its form the natural breast and a rear side which faces the wearer's body. A fabric member covers the rear side and is attached solely to the peripheral edge of the plastic sheets of the prosthetic body to thereby increase the comfort of wearing the breast prosthesis. The fabric member is suitably made of thermoplastic material, with the welding of the plastic sheets and the welding of the fabric member with the plastic sheets being carried out in a single working step.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 131 words
A method of making a breast prosthesis to be worn on the body of a person who has had a mastectomy, comprising the steps of: forming a bag with an inlet opening by suitably welding two plastic sheets to each other along a common weld which later defines the perimeter of the prosthesis and welding a fabric member of thermoplastic material to one side of the bag only along the common weld, which fabric member later defines the rear side of the prosthesis; placing the bag in a mold having a cavity of a configuration corresponding to the front side of the prosthesis resembling the person's natural breast; introducing a non-vulcanized silicone rubber through the inlet opening of the bag; and applying heat to the bag to cross-link the silicone rubber.
Claim 2
Independent Claim 131 words
A method of making a breast prosthesis to be worn on the body of a person who has had a mastectomy, comprising the steps of: forming a bag with an inlet opening by suitably welding two plastic sheets to each other along a common weld which later defines the perimeter of the prosthesis and welding a fabric member of thermoplastic material to one side of the bag only along the common weld, which fabric member later defines the rear side of the prosthesis; placing the bag in a mold having a cavity of a configuration corresponding to the front side of the prosthesis resembling the person's natural breast; introducing a non-vulcanized silicone rubber through the inlet opening of the bag; and applying heat to the bag to cross-link the silicone rubber.
Claim 3
Dependent Claim 39 words
The method of claim 1 wherein the plastic sheets and the fabric member have a border section which projects beyond the perimeter and is separated up to the weld after said heat applying step in a final processing step.
