  • Reinforced radius mammary prostheses and soft tissue expanders
    Patent number: 6605116
    Abstract: 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.
