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 barrel s from proximal to distal positions for injecting the components through outle ts of the barrels. An auto-injector assembly may be coupled to the plunger apparatus, and includes a spring mechanism locked in an inactive condition a nd an actuator activatable to release the spring mechanism, whereupon the sprin g mechanism automatically advances the plunger assembly towards the distal position to inject the components from the barrels. |
