Title (EN) PERCUTANEOUS CATHETER AND GUIDEWIRE HAVING FILTER AND MEDICAL DEVICE DEPLOYMENT CAPABILITIES
(FR) CATHETER PERCUTANE ET FIL-GUIDE A CAPACITE DE DEPLOIEMENT DE FILTRE ET DE DISPOSITIF MEDICAL
Abstract:
(EN) An apparatus and method for treating stenosed blood vessels is provided, more particularly a percutaneous catheter (10) including a filter (30) for capturing loose embolic material used to deliver a stent (20) preferably within the ascending aorta, the aortic arch, or the carotid arteries. The catheter (10) includes an expandable stent (20) deployed on an inflatable balloon (16), or alternatively a self-expanding stent. A filter (30) assembly is provided either directly on the catheter (10), or in a separate sheath (32), or on a guidewire (40). The filter assembly (30) comprises an expansion frame (52) having filter mesh (60) attached to it disposed on a guidewire (40) inserted through the catheter (10), or sheath (32), or alternatively attached directly on a distal region of the catheter (10). The expansion frame (52) comprises a structure which is activated from a contracted condition into an enlarged condition in a blood vessel, thereby traversing the vessel with the filter mesh (60). The expansion frame (52) includes biased struts, a mechanically operated frame, and/or a fluid operated frame. The catheter (10) is percutaneously introduced into a blood vessel and directed to a target region. The stent (20) is localized across the region. The filter assembly (30) is opened, and the stent (20) is deployed substantially permanently engaging the walls of the blood vessel, thereby opening the stenosed region and/or containing aortic plaque.
(FR) L'invention concerne un appareil et un procédé pour le traitement des vaisseaux sanguins sténosés, et plus particulièrement un cathéter percutané (10) comprenant un filtre (30) pour recueillir tout matériau embolique mobile, qui permet de placer un extenseur (20) de préférence dans l'aorte ascendante, la crosse de l'aorte ou les artères carotides. Le cathéter (10) comprend un extenseur à expansion (20) déployé sur un ballon gonflable (16), ou encore un extenseur auto-expansif. Un ensemble filtre (30) est placé directement sur le cathéter (10) ou dans une gaine séparée (32), ou bien sur un fil-guide (40). L'ensemble filtre (30) comporte un cadre d'expansion (52) auquel est fixé un réseau maillé filtrant (60), disposé sur un fil-guide (40) inséré dans le cathéter (10), ou la gaine (32), ou encore rattaché directement à une région distale du cathéter (10). Le cadre d'expansion (52) comprend une structure qui est activée de l'état replié à l'état déployé dans un vaisseau sanguin, traversant ainsi le vaisseau avec le réseau maillé filtrant (60). Le cadre d'expansion (52) comporte des montants en diagonale, un cadre à fonctionnement mécanique, et/ou un cadre activé hydrauliquement. Le cathéter (10) est introduit par voie percutanée dans un vaisseau sanguin et dirigé vers une zone cible. L'extenseur (20) est placé sur la section de cette zone. L'ensemble filtre (30) est ouvert, et l'extenseur (20) est déployé de manière sensiblement permanente, ancré sur les parois du vaisseau sanguin, ce qui permet d'ouvrir la région sténosée et/ou de contenir la plaque aortique.
