Abstract
An implantable prosthesis includes a shell having an apex, a base, a radius located between the apex and the base, and a dome extending between the apex and the radius. The shell has an outer surface and an inner surface that surrounds an interior volume of the shell. At least one rib is integrally formed with the inner surface of the shell and projects inwardly from the inner surface of the shell into the interior volume of the shell. The shell has an interior volume that is adapted to receive a biocompatible filler material.
Claims21
An implantable prosthesis comprising:
- a shell having an apex, a base, a radius located between said apex and said base, and a dome extending between said apex and said radius;
- said shell having an outer surface and an inner surface that surrounds an interior volume of said shell;
- and
- at least one rib integrally formed with said inner surface of said shell and projecting inwardly from said inner surface into said interior volume of said shell.
An implantable prosthesis comprising:
- a shell having an apex, a base, a radius located between said apex and said base, and a dome extending between said apex and said radius;
- said shell having an outer surface and an inner surface that surrounds an interior volume of said shell;
- at least one circumferential rib that is integrally formed with said shell, that extends around the radius of said shell, and that projects inwardly from said inner surface of said shell into said interior volume of said shell;
- and
- at least one radially extending rib that is integrally formed with said shell, that extends between said apex and said base of said shell, and that projects inwardly from said inner surface of said shell into said interior volume of said shell.
A method of making an implantable prosthesis comprising:
- obtaining a shell having a first major surface and a second major surface;
- applying at least one rib to said first major surface of said shell so that said at least one rib projects from said first major surface of said shell;
- configuring said shell so that said second major surface of said shell defines a convexly curved outer surface of said shell and said first major surface defines a concave inner surface of said shell, wherein said at least one rib projects inwardly from said concave inner surface of said shell and into an interior volume of said shell.
