Method of manufacturing an implantable article provided with a micropillared surface

摘要: A method is provided for manufacturing an implant such as envelope (19) a mammary prosthesis intended implantation in human breast which with surface having outwardly projecting micropillars (22). The involves providing three dimensional mandrel (16), the outer of has array depressions (20) constituting said pillars negative relief, applying crosslinkable elastomer-forming liquid dispersion polymer polyurethane or polydimethylsiloxane to surface, subjecting and elevated pressure, crosslinking while under pressure stripping resultant elastomeric other object from mandrel.
