Title (EN) A DEVICE AND METHOD FOR CROSSING OCCLUSIONS
(FR) DISPOSITIF ET PROCÉDÉ DESTINÉS À TRAVERSER DES OCCLUSIONS
Abstract:
(EN) A catheter (1) adapted to cross occlusions in vessels of a patient. The catheter is having a proximal end reversibly insertable adjacent to the occlusion and a distal opposite end located outside the patient. When the pusher (10) in the OPEN configuration, it provides a preset void volume barriered by means of the pusher, the proximal end of the catheter and the inner surface of the vessel. The vacuum generating mechanism applies suction on the occlusion and on the inner surface of the vessel through the void volume, to collapse and fix the tissues around the pusher and to stabilize the pusher of the catheter so that the occlusion can be penetrated with a guide-wire (13).
(FR) L'invention porte sur un cathéter (1) apte à traverser des occlusions dans des vaisseaux d'un patient. Le cathéter comporte une extrémité proximale pouvant être introduite de façon réversible adjacente à l'occlusion et une extrémité distale opposée située à l'extérieur du patient. Lorsque le poussoir (10) se trouve dans la configuration OUVERTE, il fournit un volume de vide préréglé cloisonné au moyen du poussoir, de l'extrémité proximale du cathéter et de la surface interne du vaisseau. Le mécanisme générant un vide applique une aspiration sur l'occlusion et sur la surface interne du vaisseau à travers le volume de vide, pour collaber et fixer les tissus autour du poussoir et pour stabiliser le poussoir du cathéter de telle sorte qu'un fil de guidage (13) puisse pénétrer dans l'occlusion.
