The mammary prostheses of the invention have a self-sealing area in the upper pole region of the anterior face. The self-sealing area is greater than that of a traditional filling port, and reduces the severity of the consequences of an inadvertent puncture by a hypodermic needle during the filling process. Also, this self-sealing area is thicker than the material in the other areas of the prosthesis, causing fluid introduced to the prosthesis to stay in the lower pole region of the prosthesis, making the shape of the prosthesis appear more like that of a natural breast.

Tissue expander with protection against accidental puncture

The prosthesis of the invention are configured such that the average thickness of the shell in the region where the posterior and anterior faces meet is greater, e.g., at least twice, the average thickness of the shell in the region of the anterior face. This reinforcement can reduce or eliminate undesirable scalloping effects along the upper perimeter of the prosthesis that can otherwise occur when gravity pulls downward on a filled prosthesis. Moreover, because the reinforcement is preferably confined to a radius/posterior region extending at least part of the way around the perimeter of the prosthesis, it is possible for the shell of the prosthesis in nearly the entire anterior face of the prosthesis to be formed of relatively thin material. This preserves a natural appearance of the prosthesis when it is implanted.
