Claim Text:
1. A method of making a shell for a gel-filled prosthetic implant, comprising: providing a mold having a cavity and defining a generally oval vertical cross-section with a first face opposed to a second face and separated by a perimeter region; introducing a silicone elastomer into the mold cavity; causing the silicone elastomer to distribute generally evenly around the entire mold cavity; curing the silicone elastomer to form a hollow implant shell; introducing a first silicone elastomer gel into the hollow implant shell; causing the first silicone elastomer gel to distribute generally evenly around a perimeter region of the hollow implant shell; allowing the first silicone elastomer gel to coalesce and form a ring within the perimeter region of the hollow implant shell; and removing the implant shell from the mold cavity.
