Method for fabricating prosthesis material

Procede de fabrication de materiaux pour protheses

Abstract

Procédé de fabrication de matériaux pour prothèses, notamment vasculaires, composés d'un polymère synthétique et présentant des caractéristiques désirables de porosité et d'égalité améliorées ainsi que des dimensions plus uniformes. Le procédé consiste à produire par précipitation à partir d'une solution un polymère synthétique sur la paroi interne d'un tube ou autre conduite cylindrique, la précipitation étant exécutée en présence d'une solution de précipitation qui constitue une interface liquide-liquide pour la formation de la surface interne du matériau synthétique.
A method of fabricating a prosthesis material, particularly vascular, made of a synthetic polymer and having improved smoothness, desirable pore characteristics along with more uniform dimensions. The method involves fabrication by precipitation of a synthetic polymer from a solution onto the inside wall of a tube or other cylindrical conduit, the precipitation being carried out in the presence of a precipitating solution which provides a liquid-liquid interface for the formation of the inner surface of the synthetic material.
