An apparatus (20) for sealing a puncture in a blood vessel is disclosed having a tissue-confining device (24) for compressing tissue in the vicinity of the puncture, which longitudinally extends between a proximal end and a distal end and is connected to an adjustable artery clamp (22) for controllably applying pressure, such as by a fluid circuit, onto the blood vessel, so as to reduce the hemostatis time. The artery clamp (22) comprises in a preferred embodiment a proximal plunger (60) and a distal plunger (70) positioned upstream and downstream, respectively, to the puncture. The apparatus (20) is also suitable for treating a pseudoaneurysm.
L'invention concerne un appareil permettant de sceller un vaisseau sanguin percé, comprenant un dispositif confinant le tissu qui sert à comprimer le tissu aux alentours de l'endroit percé. Ce dispositif s'étend en direction longitudinale entre une extrémité proximale et une extrémité distale et est relié à un clamp artériel réglable qui permet d'exercer, de manière contrôlée, de la pression sur le vaisseau sanguin, par exemple au moyen d'un circuit fluide, afin de réduire le temps d'homéostasie. Dans un mode de réalisation préféré, le clamp artériel comprend un piston proximal ainsi qu'un piston distal qui sont disposés respectivement en amont et an aval de l'endroit percé. L'appareil selon l'invention convient également au traitement de pseudoanevrysme.
