A method for forming an open cell texturized surface in a silicone elastomer layer of a breast implant, or other medical implant, is created by forming a layer of uncured silicone elastomer, applying a coating of particles to the surface thereof, and curing the layer by heating it at an elevated temperature which also volatilizes the particles such that their constituent gases boil through the surface of the layer and create the texturing.
L'invention concerne un procédé de formation d'une surface texturée à alvéoles ouverts dans une couche élastomère silicone pour prothèse du sein ou autre implant médical. Ce procédé consiste à former une couche d'élastomère silicone non durci sur laquelle une couche de particules est appliquée, à durcir la couche d'élastomère par traitement thermique à une température élevée permettant aux particules de s'évaporer de sorte que leurs gaz constitutifs remontent à la surface de la couche par un processus analogue à une ébullition et créent ladite texturation.
