A multi-lumen mammary prosthesis for surgical implantation comprising:
- an outer, closed, broad-based flexible envelope of medical grade elastomer containing a first fluid material,
- an unattached second, closed, flexible envelope contained in said first fluid material and being motile therewithin, said second envelope being substantially spherical in shape and containing a second fluid material, the diameter of said substantially spherical envelope being sufficient to maintain outward projection of the prosthesis.
A multi-lumen mammary prosthesis for surgical implantation comprising:
- an outer closed broad- based flexible envelope of medical grade silicone elastomer containing a silicon gel material,
- an unattached second closed flexible silicone elastomer envelope contained in said gel material and being motile therewithin, said second envelope being substantially spherical in shape and also containing a silicone gel material, the diameter of said substantially spherical envelope being sufficient to provide and maintain outward projection of the prosthesis.
