Mammary prosthesis which resists capsular contracture

摘要

A surgically implantable mammary prosthesis comprises a sac containing a filler material. The filler material is present in an amount sufficient to give the sac a relatively low profile shape and a pliant, responsive nature. The prosthesis includes a restraining means for resisting the tendancy of tissue to form the prosthesis into a sphere. The restraining means functions reactive to tissue pressure and does not substantially reduce the pliant, responsive nature of the prosthesis.
