The present invention relates to a process for manufacturing a porous metal- containing material, comprising the steps of providing a composition comprising particles dispersed in at least one solvent, the particles comprising at least one polymer material and at least one metal-based compound; substantially removing the solvent from said composition; substantially decomposing the polymer material, thereby converting the solvent free particles into a porous metal-containing material. The present invention further relates to metal- containing materials produced in accordance with the above process and their use in implantable medical devices.
L'invention concerne un procédé permettant de fabriquer un matériau contenant un métal poreux. Ce procédé consiste à préparer une composition contenant des particules dispersées dans au moins un solvant, ces particules contenant au moins un matériau polymère et au moins un composé à base de métal ; à éliminer sensiblement le solvant de la composition ; à décomposer sensiblement le matériau polymère, convertissant les particules exemptes de solvant en un matériau contenant un métal poreux. L'invention concerne également des matériaux contenant un métal produits conformément au procédé décrit ci-dessus et leur utilisation dans des dispositifs médicaux implantables.
