Patent ID: 7766963

Claim:
An external breast prosthesis, comprising: (a) front skin formed entirely from a mixture of an elastomeric polymer, a non-volatile additive and a plasticizing oil, said front skin configured and dimensioned in a shape that approximates a form of a human breast; (b) a rear skin joined with said front skin and forming a cavity therebetween; (c) a gel disposed in said cavity; and (d) wherein said front skin has a cratered outer surface formed from said mixture by mixing together said plasticizing oil, said polymer, that together with said plasticizing oil forms said elastomeric polymer, and a predetermined amount of at least one additive to form said mixture; the predetermined amount of additive being in excess of an amount of additive that is soluble in the mixture at room temperature; increasing the temperature of the mixture to at least a melting point where the mixture becomes molten and the additive is soluble in the molten mixture in a stable solution; and allowing the mixture to cool to form said elastomeric polymer under conditions whereby the additive precipitates and migrates from the mixture to the surface of the elastomeric polymer, leaving craters on the surface of the elastomeric polymer.
