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.
