Abstract
Abstract A breast prosthesis is formed in a mold cavity from a soft silicone rubber cross-linked with hardeners. The prosthesis has a convex outwardly facing surface and a concave cup-shaped inwardly facing surface. The outer surface has a nipple and an areola with a passage formed through the nipple between the inwardly facing and outwardly facing surfaces. The prosthesis can be sized to fit into standard brassieres with its edge located inwardly of the adjacent edge of the brassiere. Extending laterally from one side of the prosthesis is a unitary flap for covering the axillary lymph-gland area. Additional flaps may be molded and glued to the base portion of the prosthesis to cover scar areas not covered by the base part.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
233 words
A breast prosthesis die cast and formed of a skin-colored soft silicone rubber cross-linked with an amount of hardeners such that it vulcanizes to a soft elastic material forming a prosthesis having an outer surface facing outwardly away from a wearer and an inner surface facing inwardly toward the wearer, and comprising an integral base including a central part, an edge extension and a flap-like section, said central part having a convex outer surface and a concave inner surface providing a hollow cup-shaped form, said convex outer surface having the shape of a female breast including a nipple and an areola, said concave inner surface having a breast-like shape and being spaced from the outer surface providing therebetween the wall thickness of the central part, and said central part having a passage through said nipple extending from the outer surface to said inner surface, said edge extension being thin and flexible and laterally enclosing said central part, said edge extension having a width outwardly from said central part so that said edge extension does not extend outwardly from the edge of a brassiere with which it is worn, said flap-like section connected to said edge extension and extending laterally outwardly from said central part toward the closer side of the wearer with said flap-like section having a length and width sufficient for covering the axillary lymph-gland area when the prosthesis is in place.

Claim 3
Dependent Claim
19 words
A breast prosthesis, as set forth in claim 1, wherein red fibers are mixed with said soft silicone rubber.
Claim 4
Dependent Claim
30 words
A breast prosthesis, as set forth in claim 1, wherein at least one additional passage is formed between the inner and outer surface of said central part under said areola.
Claim 5
Dependent Claim
30 words
A breast prosthesis, as set forth in claim 1, wherein additional passages are formed between the inner and outer surfaces of said central part under and laterally of said areola.
Claim 6
Dependent Claim

Claim 9
Dependent Claim
32 words
A breast prosthesis, as set forth in claim 5, wherein said at least one additional part has a longitudinally extending attachment edge and said attachment edge has a stepped depression formed therealong.
Claim 10
Dependent Claim
31 words
A breast prosthesis, as set forth in claim 1, wherein said at least one additional part comprises a sickle-shaped flap having a concavely shaped edge for attachment to said edge extension.
Claim 11
Dependent Claim
