Abstract

L'invention concerne un cathéter (12) relié à un système d'entraînement en rotation (20), dont l'extrémité avant (12a) est pourvue d'un outil tranchant comprenant un stator (14) et un rotor (16). Des lames montées sur la face périphérique du rotor (16) et du stator (14) coopèrent à la manière de ciseaux. Les dépôts détachés sont acheminés à travers un manchon tubulaire (22) jusqu'à un récipient collecteur (28), en passant par une chambre d'évacuation (18). L'acheminement est assuré par un arbre d'entraînement se présentant sous forme de vis sans fin, placée dans le manchon tubulaire (22), qui relie le système d'entraînement en rotation (20) au rotor (16). Un cathéter rotatif de ce type sert à éliminer des thromboses et des sténoses situées dans des vaisseaux sanguins rétrécis, tels que des artères et des veines, sans endommager ces derniers.
