  • Mammary prosthesis fill and method of making same
    Patent number: 5219360
    Abstract: A surgical mammary prosthesis containing a liquid-gel of cross-linked hyaluronic acid (hylan) inside a medical grade elastomer, and a method of making a prosthesis containing such a liquid-gel. Because the gel used in the invention contains a nontoxic, nonantigenic, noninflammatory, biodegradable natural substance, problems attributed to or associated with previous silicone gel filled prostheses as a result of prosthesis rupture or leakage or "bleed" are avoided.
