Title (EN) POROUS MATERIAL PRODUCT AND PROCESS
(FR) PRODUIT A BASE DE MATERIAU POREUX ET PROCEDE CORRESPONDANT
Abstract:
(EN) A porous implant and method of making such is disclosed. A mold form material (164) is created by adhering solid particles together to form a porous network. A liquid phase of a final product is forced through the interstices of the mold form (164), and then most of the liquid material is forced out of the interstices leaving a thin coat (162). Next, the thin coat is cured to produce a thin coat of a polymer such as silicone rubber (162). Next, the mold form material (164) is dissolved out creating a porous structure containing only the cured polymer.
(FR) L'invention porte sur un implant poreux et sur son procédé de fabrication. On crée un matériau pour empreinte de moule (164) en faisant adhérer ensemble des particules solides afin de constituer un réseau poreux. On force une phase liquide du produit final à traverser les interstices de l'empreinte de moule (164), la majeure partie du matériau liquide est alors refoulée des interstices, une couche mince (162) étant ainsi créée. On fait ensuite durcir cette mince couche en vue d'obtenir une fine couche d'un polymère tel qu'un élastomère de silicone (162). Et, enfin, on dissout le matériau pour empreinte de moule (164) afin de produire une structure poreuse ne contenant plus que le polymère durci.
