Title (EN) INTRALUMENAL MATERIAL REMOVAL SYSTEMS AND METHODS
(FR) SYSTEMES ET PROCEDES DE RETRAIT DE MATIERE INTRALUMINALE
Abstract:
(EN) Intralumenal material removal systems are provided. The intralumenal material removal system includes a cutter assembly (50) positionable in the lumen of a mammalian subject and operably connected to system controls (14). One composite cutter assembly (50) comprises a distal, fixed diameter cutter (52) and a proxiaml, adjustable diameter cutter (54), the cutter assembly being axially advanceable by translating the drive shaft and rotatable by rotating the drive shaft. The adjustable cutting assembly (54) is adjustable between a smaller diameter condition and a larger diameter condition by rotation of the drive shaft in opposite directions. The cutter may thus be introduced to and withdrawn from the material removal site in a retracted, smaller diameter condition that facilitates translation and navigation of the device through various lumens. The adjustable cutting assembly (54) may be selectively expanded at the material removal site to facilitate cutting, removal and aspiration of the occlusive material.
(FR) Cette invention se rapporte à un système de retrait de matière intraluminale, qui comprend un ensemble de coupe (50) pouvant être placé dans la lumière du passage corporel chez un sujet mammifère et qui est raccordé en mode opérationnel à des commandes (14) du système. Un tel ensemble de coupe composite (50) comprend un couteau de diamètre fixe distal (52) et un couteau de diamètre réglable proximal (54). Cet ensemble de coupe peut progresser axialement par translation de l'arbre d'entraînement et il peut tourner par rotation de l'arbre d'entraînement. Le couteau réglable (54) peut être réglé entre une configuration de petit diamètre et une configuration de grand diamètre, par rotation de l'arbre d'entraînement dans des directions opposées. Le couteau peut ainsi être introduit et retiré du site de retrait de matière dans une configuration repliée de petit diamètre qui facilite les mouvements de translation et de navigation du dispositif dans divers passages corporels. Le couteau réglable (54) peut être déployé sélectivement au niveau du site de retrait de matière, pour faciliter la découpe, le retrait et l'aspiration de la matière occlusive.
