Abstract

Selon l'invention, l'appareil pour prévenir la resténose comprend un corps cylindrique dimensionné pour être implanté dans un vaisseau sanguin ou un stent. Une pluralité de lames est positionnée à l'intérieur du corps et génère un mouvement de rotation de l'appareil lors de l'écoulement du sang à travers l'appareil. Le dispositif inclut également une pluralité de crêtes disposées sur la surface externe du corps. Lors de l'écoulement du sang à travers l'appareil, les lames sont déviées, faisant tourner le corps pour brosser doucement les parois intérieures du vaisseau sanguin ou du stent, ou l'espace directement adjacent à ces parois intérieures. Le mouvement de rotation doux et sensiblement continu de l'appareil empêche la formation de tartre sans endommager les parois vasculaires ou les stents implantés. L'appareil est composé d'un matériau biocompatible de sorte à pouvoir être installé et laissé à fonctionner à l'intérieur du corps sans remplacements fréquents.
