Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from prior interventional procedures. A sealing member (40) is deployed intravascularly into the target vessel, and an anchor member (50) is deployed extravascularly of the target vessel. The sealing member and the anchor member are connected by a suture (60) that may be drawn to tighten the sealing member and the anchor member relative to one another in order to effect the seal of the puncture wound. After tightening, the suture is secured to maintain the sealing member and the anchor member relative to one another in order to maintain the seal. Preferably, the anchor member, the suture and the sealing member are comprised of biocompatible, bioresorbable materials that are absorbed into the body after the sealing of the puncture wound has been achieved. The sealing member, suture and the anchor member are delivered by a delivery rod (50) or other components over a guidewire (30) or through an introducer already in place from the preceding interventional procedure.

L'invention concerne des systèmes de fermeture de blessures de vaisseau et un procédé pour refermer une blessure perforante dans un vaisseau cible, telle que les blessures perforantes qui se produisent suite à des procédures interventionnelles antérieures. Un élément de fermeture est déployé de manière intravasculaire dans le vaisseau cible et un élément d'ancrage est déployé de manière extravasculaire au vaisseau cible. L'élément de fermeture et l'élément d'ancrage sont raccordés par une suture qui peut être tirée pour resserrer l'élément de fermeture et l'élément d'ancrage l'un par rapport à l'autre afin de réaliser la fermeture de la blessure perforante. Après le resserrage, la suture est bien fermée pour maintenir l'élément de fermeture et l'élément d'ancrage l'un par rapport à l'autre afin de conserver la fermeture.
