Apparatus for sealing a puncture communicating with a blood vessel includes an introducer sheath, an occlusion member with a balloon thereon, a retraction assembly, and a syringe assembly including sealing material therein. The syringe assembly may include a pair of syringe barrels having sealing components therein, and a plunger assembly biased to slide within the barrels from proximal to distal positions for injecting the components through outlets of the barrels. An auto-injector assembly may be coupled to the plunger apparatus, and includes a spring mechanism locked in an inactive condition and an actuator activatable to release the spring mechanism, whereupon the spring mechanism automatically advances the plunger assembly towards the distal position to inject the components from the barrels.

L'invention porte sur un appareil d'obturation d'une ponction en communication avec un vaisseau sanguin comprenant une gaine, un élément d'occlusion équipé d'un ballonnet, un ensemble de rétraction, et un ensemble seringue contenant le matériau d'obturation. L'ensemble seringue peut comprendre une paire de corps de seringue pourvus de composants d'obturation, et un ensemble piston orienté de manière à glisser dans les corps d'une position proximale en une position distale afin d'injecter les composants à travers les sorties des corps. Un ensemble d'auto-injection peut être relié au piston, et comprend un mécanisme de ressort verrouillé dans un état inactif et un actionneur pouvant être activé pour libérer le mécanisme de ressort, ce mécanisme de ressort poussant alors automatiquement l'ensemble piston en position distale afin d'injecter les composants contenus dans les corps.
