Abstract
An implant is provided with an open-celled silicone elastomer foam outer layer. The implant may be formed by compressively deforming beads mixed with liquid elastomer in a mold containing a preformed support structure. The elastomer is cured and the beads dissolved out. Infusion and sensor catheters covered with the foam provide improved transport rates and faster response.
Claims7
A method for making an implant to be implanted into an animal or human being, said method comprising:
- placing a support structure in a mold;
- placing an uncured polymeric material in said mold;
- placing deformable beads in said mold;
- compressing said mold to deform said beads into general mutual contact;
- curing said polymeric material to bond it to said support structure and to form a solid interconnected matrix between said deformed beads;
- and
- removing said deformed beads from said matrix, whereby an implant having a polymeric open-celled foam surface is provided.
