Abstract
A carvable implant material for use in surgery and especially in plastic and reconstructive surgery is described which comprises porous PTFE having a coating of a stiffening agent intended to stiffen the PTFE in order to render it carvable. This material may thus be carved into a desired shape prior to implantation. The stiffening agent is biodegradable to allow tissue ingrowth to stabilize the location of the implant as the biodegradable stiffening agent is degraded and absorbed by the body.
