Abstract

Abstract A biologically compatible human breast implant is disclosed which has improved natural feel and is resistant to leakage. In the disclosed implant, a large quantity of small, pliable hollow spheroids of polymeric material are used as a filler within the implant shell. The hollow spheroids are partially filled with a fluid when in an uncompressed state, and provide a cushioning effect by being compressible to the point where the resulting reduction in the interior space causes the interior to become essentially filled by the fluid and where further compression is resisted due to the relative non-compressibility of the contained fluid. The described spheroids are made of silicone rubber and are partially filled with saline solution. The spheroids have an outside diameter of from about 1 mm to 5 mm, an outer wall thickness of about 75 to 225 microns, and the fluid contained therein is filled to about 80 to 90% of capacity when the spheroids are in their naturally uncompressed spherical state.
