Title
(EN) BALLOON ENCAPSULATION AND ISOVOLUMETRIC SUCTION THROMBECTOMY CATHETER AND METHODS THEREOF
(FR) CATHÉTER D'ENCAPSULATION DE BALLONNET ET DE THROMBECTOMIE À ASPIRATION ISOVOLUMÉTRIQUE, ET MÉTHODES ASSOCIÉES
Abstract
(EN)
The disclosure provides for an adjustable catheter system with isovolumetric suction and restoration of fluid for the removal of a thrombus and a method of use thereof. The catheter system includes an inner catheter and an outer sheath surrounding at least a portion of the inner catheter. The inner catheter may include at least three lumina extending from the proximal end to the distal end of the inner catheter, at least one infusion fenestration along the infusion segment, and a distal encapsulation balloon at the distal end. The outer sheath may include at least three lumina extending from the proximal end to the distal end of the outer sheath and a proximal encapsulation balloon at the distal end. The catheter system may further include an agitator for mechanical morcellation of the thrombus.
(FR)
L'invention concerne un système de cathéter réglable à aspiration isovolumétrique et restauration de fluide pour l'élimination d'un thrombus, et méthode d'utilisation associée. La système selon l'invention contient un cathéter interne et une gaine externe entourant au moins une partie du cathéter interne. Le cathéter interne peut comprendre au moins trois lumières s'étendant de son extrémité proximale à son extrémité distale, au moins une fenestration de perfusion le long du segment de perfusion, et un ballonnet à encapsulation distale au niveau de l'extrémité distale. La gaine externe peut comprendre au moins trois lumières s'étendant de son extrémité proximale à son extrémité distale, et un ballonnet à encapsulation proximale au niveau de l'extrémité distale. Le système de cathéter selon l'invention peut en outre comprendre un agitateur pour le morcellement mécanique du thrombus.
