Title
(EN) APPARATUS AND METHODS FOR REMOVING OBSTRUCTIVE MATERIAL FROM BODY LUMENS
(FR) APPAREIL ET PROCÉDÉS DESTINÉS À ENLEVER LA MATIÈRE QUI OBSTRUE DES LUMIÈRES CORPORELLES
Abstract
(EN)
An apparatus is provided for removing material within a body lumen that includes a catheter including a proximal end, a distal end for introduction into a body lumen, and an aspiration lumen extending therebetween; a guide member extending from the distal end and terminating in a distal tip, the guide member comprising a track adjacent a track lumen extending from the distal tip into the aspiration lumen; and an obstruction clearing device deployable from the guide member and retractable along the track. In addition or alternatively, the apparatus includes a cutting head reciprocable within the aspiration lumen adjacent the distal end for macerating material being aspirated into the aspiration lumen.
(FR)
L'invention concerne un appareil qui retire de la matière dans une lumière corporelle et qui comprend un cathéter qui présente une extrémité proximale, une extrémité distale destinée à être introduite dans une lumière corporelle et une lumière d'aspiration qui s'étend entre ses extrémités, un élément de guidage qui part de l'extrémité distale et qui se termine dans une pointe distale, l'élément de guidage comprenant une piste adjacente à une lumière de piste qui s'étend entre la pointe distale et la lumière d'aspiration, et un dispositif de nettoyage de l'obstruction qui peut être déployé depuis l'élément de guidage et rétracté le long de la piste. En supplément ou en variante, l'appareil comprend une tête de coupe qui peut être déplacée en va-et-vient dans la lumière d'aspiration en position adjacente à l'extrémité distale pour déchiqueter la matière aspirée dans la lumière d'aspiration.
