Title
(EN) FISTULA FORMATION DEVICES AND METHODS THEREFOR
(FR) DISPOSITIF DE FORMATION DE FISTULE, ET MÉTHODES ASSOCIÉES
Abstract
(EN) Described here are devices, systems, and methods for forming a fistula between two blood vessels. Generally, the systems may comprise a first catheter and a second catheter, which may comprise one or more fistula-forming elements. The first and second catheters may comprise one or more magnets, which may be used to assist in bringing the first and catheters in closer proximity to facilitate fistula formation. In some variations, the magnet may have a plurality of magnetic domains each characterized by a magnetic flux vector, with the magnetic flux vectors of the magnet passing through a common magnetic origin.
(FR) L'invention concerne des dispositifs, des systèmes et des procédés pour former une fistule entre deux vaisseaux sanguins. D'une façon générale, lesdits systèmes peuvent comprendre un premier cathéter et un second cathéter qui peuvent comprendre un ou plusieurs éléments de formation de fistule. Les premier et second cathéters peuvent comprendre un ou plusieurs aimants qui peuvent être utilisés pour aider à amener les premier et second cathéters très proches l'un de l'autre afin de faciliter la formation d'une fistule. Dans certaines variantes, l'aimant peut avoir une pluralité de domaines magnétiques, chaque domaine étant caractérisé par un vecteur de flux magnétique, les vecteurs de flux magnétique de l'aimant passant par une origine magnétique commune.
