Title (EN) TAVR VALVE GUIDEWIRE AND GUIDETUBE WITH ADJUSTABLE DISTAL LOOP
(FR) FIL-GUIDE DE VALVULE POUR PROCÉDURE ITVA ET TUBE DE GUIDAGE AVEC BOUCLE DISTALE RÉGLABLE
Abstract:
(EN) A microcatheter device for crossing a patient's aortic valve has a guidetube combined with a free-floating and removable guidewire. The guidetube is generally hollow with a main shaft and a distal ring, the main shaft and the distal ring formed from flexible plastic. The distal ring is larger in diameter than the main shaft, and is configured to conform to an internal guidewire for insertion into the aorta, and then to deploy to form a downwardly-extending loop when in place in the left ventricle. A guidewire is received by the guidetube and is configured to advance into the distal ring to cause a diameter of the distal ring to expand, retract, or completely straighten. The distal ring diameter is thus adjustable to fit the size of the patient's left ventricle.
(FR) La présente invention concerne un dispositif de microcathéter destiné à traverser la valvule aortique d'un patient, le dispositif comportant un tube de guidage combiné à un fil-guide flottant amovible. Le tube de guidage est globalement creux et pourvu d'un arbre principal et d'un anneau distal, l'arbre principal et l'anneau distal étant constitués de plastique souple. L'anneau distal est plus grand en diamètre que l'arbre principal, et il est conçu pour se conformer à un fil-guide interne en vue d'être inséré dans l'aorte, puis pour se déployer et former une boucle s'étendant vers le bas lorsqu'elle est en place dans le ventricule gauche. Un fil-guide est reçu par le tube de guidage et il est configuré pour avancer dans l'anneau distal, afin d'amener un diamètre de l'anneau distal à se dilater, se rétracter ou se redresser complètement. Le diamètre de l'anneau distal peut ainsi être ajusté pour s'adapter à la taille du ventricule gauche du patient.
