The invention provides a material for medical use in humans and/or animals bearing a biologically active agent, said material being multilayered, as well as a device of this material and a method to produce it. The material comprises a core material, wherein said core material is formed into a body, optionally into a body having the shape of a finished device; two or more layers of coating material of which the first layer has been applied onto said core material and additional layers have been applied onto said coating material of a preceding layer; and wherein at least one of the layers comprise said biologically active agent. Characteristic for this material is that the coating material is a biopolymer, a sol-gel produced silica gel or a biologically active molecule.
L'invention concerne une matière à usage médical pour les personnes et/ou les animaux, renfermant un principe biologiquement actif, cette matière étant multicouche, ainsi qu'un dispositif constitué de cette matière et son procédé de fabrication. La matière comprend une matière centrale formant un corps qui peut éventuellement avoir la forme d'un dispositif fini, deux couches ou plus de matière de revêtement, la première étant appliquée sur la matière centrale et les couches suivantes étant appliquées sur la matière de revêtement d'une couche précédente, une couche au moins renfermant ledit principe biologiquement actif. La caractéristique principale de cette matière est que la matière de revêtement est un biopolymère, un gel de silice fabriqué à partir d'un procédé sol-gel, ou une molécule biologiquement active.
