Abstract:
A self-positioning multi-lumen mammary prosthesis for surgical implantation with a predetermined orientation within a human body comprising:an outer closed envelope of medical grade elastomer with upper and lower portions, and a first fluid material of a given density contained in said outer closed envelope; andan inner closed envelope of medical grade elastomer disposed within said outer closed envelope and fixed thereto in the lower portion thereof, and said inner closed envelope containing a second fluid material of a given density which is greater than said density of said first fluid material; and,said inner closed envelope containing said second fluid material of a given density being fixed within said lower portion of said outer closed envelope with the center of gravity of said inner closed envelope containing said second fluid below the center of gravity of said outer closed envelope containing said first fluid material;whereby the mammary prosthesis is maintained in or returned to its predetermined position by the higher density of the second fluid material which is the lower portion of said outer closed envelope.
