Procedes de fabrication de protheses poreuses

Methods for the manufacture of porous prosthesis

Abstract

La présente invention concerne un procédé de fabrication d'une prothèse poreuse biocompatible. En l'occurrence, on prend une structure support poreuse destinée à une prothèse, et on y applique un copolymère bloc biocompatible en solution dans un premier solvant approprié. Ce copolymère bloc réunit un ou plusieurs blocs élastomères et un ou plusieurs blocs thermoplastiques. On y applique ensuite un second solvant capable de dissoudre le premier solvant, mais incapable de dissoudre le copolymère sur les surfaces de la prothèse considérée. Il en résulte que le copolymère précipite sur la structure support.
A method for the manufacture of a biocompatible porous prosthesis comprising the steps of applying a solution to a porous support structure for a prosthesis, said solution comprising a biocompatible block copolymer including one or more elastomeric blocks and one or more thermoplastic blocks, and a first solvent capable of dissolving said copolymer; and applying a second solvent capable of dissolving said first solvent but incapable of dissolving said copolymer to the surfaces of said prosthesis and thereby causing said copolymer to precipitate onto said support structure.
