A medical device having a bio-active coating is prepared by providing a polymeric substrate having hydroxyl and/or amine functionality on a surface thereof and applying the bio-active coating to the surface. The bio-active coating is the reaction product of two different reactions. The first reaction includes reacting the polymeric substrate with a hydrophilic, isocyanate-terminated spacer having at least one isocyanate group at its first and second ends. The second reaction includes reacting a remaining, unreacted isocyanate-terminated end of the spacer with a bio-active agent to bond the bio-active agent to the spacer.

L'invention porte sur un instrument médical présentant un revêtement bioactif, que l'on prépare en disposant un substrat polymère présentant une fonction hydroxyle et/ou amine sur l'une de ses surfaces, puis en appliquant le revêtement bioactif sur ladite surface. Le revêtement bioactif est le produit réactionnel de deux réactions différentes. La première réaction consiste à faire réagir le substrat polymère avec un espaceur hydrophile à terminaisons isocyanate présentant au moins un groupe isocyanate à sa première extrémité et à sa deuxième extrémité. La seconde réaction consiste à faire réagir l'une des extrémités à terminaison isocyanate restantes, n'ayant pas réagi, de l'espaceur, avec un agent bioactif de manière à fixer l'agent bioactif à l'espaceur.
