Abstract

On décrit des cathéters d'athérectomie pourvus d'une tête de coupe cylindrique montée rotative à l'extrémité distale d'un corps de cathéter. La tête comprend une ouverture axiale allongée et un intérieur ouvert. Un élément de coupe est placé de manière contiguë à l'ouverture allongée de sorte qu'une matière athéromateuse invaginée par la tête est coupée et déviée à l'intérieur de la tête. Selon un mode de réalisation préféré, l'ouverture allongée est disposée de manière hélicoïdale autour de l'axe central de la tête cylindrique et un élément de coupe est agencé de manière solidaire le long du pourtour de l'ouverture. Selon un autre mode de réalisation, la tête cylindrique est pourvue d'une extrémité distale conique qui s'étend de manière distale à partir d'un corps destiné à la tête et comprend un prolongement de l'ouverture allongée.
