Title
(EN) APPARATUS AND METHODS FOR CLOSING VESSELS
(FR) APPAREIL ET PROCÉDÉS POUR FERMETURE DE VAISSEAUX
Abstract
(EN)
Apparatus and methods are provided for closing a tubular structure within a patient's body. The apparatus includes a needle including a proximal end including a hub, a distal end including a sharpened distal tip, a lumen having an oblong cross-section extending proximally from the distal end, and defining a longitudinal axis between the proximal and distal ends, and a clip deliverable from the lumen. The clip is compressible between a relaxed state in which a plurality of tines of the clip are shaped to engage and close a tubular structure within a patient's body, and a stressed state in which the tines are compressed to allow the clip to be loaded into the. The apparatus may also include a pusher member for deploying the clip from the distal tip of the needle such that the tines engage and close a tubular structure through which the tubular member is directed.

L'invention concerne un appareil et des procédés destinés à fermer une structure tubulaire à l'intérieur du corps d'un patient. L'appareil comprend une aiguille comprenant une extrémité proximale comprenant un moyeu, une extrémité distale comprenant une pointe distale aiguisée, une lumière ayant une section transversale oblongue s'étendant de manière proximale à partir de l'extrémité distale, et définissant un axe longitudinal entre les extrémités proximale et distale, et une agrafe pouvant être distribuée à partir de la lumière. L'agrafe est compressible entre un état relâché dans lequel une pluralité de dents de l'agrafe sont formées pour venir en prise et fermer une structure tubulaire à l'intérieur du corps d'un patient, et un état contraint dans lequel les dents sont comprimées pour permettre à l'agrafe d'être chargée. L'appareil peut également comprendre un élément poussoir pour déployer l'agrafe à partir de la pointe distale de l'aiguille de telle sorte que les dents viennent en prise et ferment une structure tubulaire à travers laquelle l'élément tubulaire est dirigé.
