Claim of US Patent No. 11,109,956

1. A gravity sensitive silicone breast implant, comprising a flexible multilayer shell and a cohesive silicone gel filler with a high elasticity and a low viscosity, the breast implant being configured to shift its maximum point of projection when subjected to gravity, wherein the flexible multilayer shell reaches at least 25% elongation at forces of about 1.4 N to about 1.9 N and at least 50% elongation at forces of about 1.8 N to about 2.2 N when tested in accordance with ASTM D412, and wherein the silicone gel filler reaches about 2 mm to about 29 mm protrusion in a cone cohesion test without detaching when tested in accordance with ASTM F703.
