Patent ID: 8480736

Claim:
A silicone gel filled artificial breast prosthesis comprising: a shell formed of a silicone material and having a hole formed there-through at a lower area of the shell, the hole having a conical shape with a wider opening at an upper surface of the shell and a narrower opening at a lower surface of the shell; a physical property complementary patch received in and attached to the conical-shaped hole of the shell, the physical property complementary patch having a planar upper surface and a planar lower surface that are, respectively, flush with the upper surface and the lower surface of the shell where the hole is formed; and a multilayered thin film patch having a planar lower surface which is bonded to the planar upper surface of the physical property complementary patch and to the upper surface of the shell adjacent the hole, the multilayered thin film patch including a blocking film for preventing leakage of low molecular weight silicone, wherein the physical property complementary patch is formed of a material softer than the silicone material forming the shell such that a combined structure of the multilayered thin film patch and the physical property complementary patch minimizes a stress concentration at an area where the combined structure is attached to the shell, despite a thickness difference between the shell and the combined structure.
