1. 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.

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.
