Patent ID: 7993409

Claim:
A lip implant sized for insertion in a human lip, the lip implant comprising: a first biocompatible solid material having a first durometer rating, the first biocompatible solid material comprising: a first middle portion defining an outside surface and having a longitudinal center axis and a geometric center point; and a pair of first tapered end portions between which the first middle portion longitudinally extends, the first tapered end portions defining respective outside surfaces, the first tapered end portions being symmetric about a transverse axis that is perpendicular to the longitudinal center axis of the first middle portion and extends through the geometric center point of the first middle portion; wherein the first biocompatible solid material is symmetric about the longitudinal center axis of the first middle portion, and is also symmetric about the transverse axis; and an outer shell surrounding the first biocompatible solid material, the outer shell being formed of a second biocompatible solid material having a second durometer rating, the second durometer rating being higher than the first durometer rating, the second biocompatible solid material comprising: a second middle portion defining inside and outside surfaces, the inside surface of the second middle portion contacting the outside surface of the first middle portion; and a pair of second tapered end portions between which the second middle portion extends, the second tapered end portions being symmetric about the transverse axis, each of the second tapered end portions defining inside and outside surfaces, the respective inside surfaces of the second tapered end portions contacting respective ones of the outside surfaces of the first tapered end portions; wherein the second biocompatible solid material is symmetric about the longitudinal center axis of the first middle portion; and wherein the second biocompatible solid material is symmetric about the transverse axis; wherein the entirety of the implant is generally shaped to correspond to the shape of said lip.
