The present invention is directed to a device (100) which is capable of both locating a punctured blood vessel wall and sealing the puncture in the vessel . In one embodiment, the device includes an elongate deployment member (7) having a sealing element (160) releasably disposed within a distal end thereof, said deployment member being coupled to a first actuator (8) configured to retract said deployment member relative to said sealing element, and an elongated indicator member (6) having a proximal end and a distal end, said indicator member extending through a lumen in said deployment member such that the distal end of said indicator member extends distally of the distal end of the deployment member, and said indicator member being coupled to a second actuator (2) configured to retract said indicator member relative to said deployment member.

Cette invention concerne un dispositif qui est capable à la fois de localiser une paroi de vaisseau sanguin percée et de fermer hermétiquement l'endroit où le vaisseau est percé, ainsi qu'un procédé d'utilisation de ce dispositif. Dans un mode de réalisation, ce dispositif comprend un élément de déploiement allongé qui comporte un élément de fermeture disposé amovible dans une extrémité distale de celui-ci et qui est couplé à un premier actionneur conçu pour permettre le retrait de l'élément de déploiement par rapport à l'élément de fermeture, et un élément indicateur allongé qui présente une extrémité proximale et une extrémité distale et qui s'étend à travers un passage de l'élément de déploiement, pour que l'extrémité distale de l'élément indicateur s'étende en position distale par rapport à l'extrémité distale de l'élément de déploiement, l'élément indicateur étant en outre couplé à un second actionneur conçu pour permettre le retrait de l'élément indicateur par rapport à l'élément de déploiement.
