Abstract
An expandable mammary implant including a shell having an anterior face and a posterior face. The anterior has an upper pole portion and a lower pole portion meeting at an apex, and an injection zone for receiving fluid therethrough to inflate the implant. A reinforcement material is coupled to the shell in a reinforcement zone. The reinforcement material is coupled to the shell so as to at least coincide with the upper pole portion and a peripheral rim portion that extends from the posterior face upwardly into said anterior face by a predetermined distance.

An expandable mammary tissue implant comprising:
- a shell having an anterior face and a posterior face having a periphery, the anterior face having an upper pole region and a lower pole region meeting at an apex, and an injection zone for receiving fluid therethrough to inflate the implant;
- a first reinforcing material having (i) a peripheral rim portion that extends from the periphery of said posterior face and (ii) an upper periphery, said first reinforcing material coupled to the shell such that the first reinforcing material does not extend along the entire anterior face;
- a second reinforcing material coupled to the shell and extending along a portion of the anterior face of the shell;
- wherein the first reinforcing material overlaps or abuts the second reinforcing material, at or adjacent the upper periphery of the first reinforcing material and in at least two locations on opposite sides in the upper pole region thereby forming a hinge point on each of said opposite side of the upper pole region, and
- wherein a portion of the lower pole region is not reinforced by either the first or second reinforcing material.
