A system for facilitating hemostasis of a puncture site in a blood vessel injects an absorbable sponge pledget in a hydrated state at an exterior of the blood vessel puncture to facilitate hemostasis. The system includes a tract dilator for locating the puncture, an introducer, and a plunger. The introducer includes a staging chamber for receiving the absorbent sponge pledget and a delivery chamber having a diameter smaller than a diameter of the staging chamber into which a hydrated pledget passes. The pledget is hydrated and compressed within the introducer and then ejected with the plunger to the delivery site to facilitate hemostasis of the blood vessel puncture. The system delivers the absorbable sponge pledget over a guidewire to ensure the proper positioning of the pledget over the puncture. The implanted absorbable sponge once delivered expands rapidly to fill the target site and is absorbed by the body over time.

[ What is claimed is:] [1.] A system for facilitating hemostasis of a puncture in the wall of a blood vessel, the system comprising:a tract dilator having a lumen for allowing the tract dilator to be passed over a guidewire;an introducer having a lumen for allowing the introducer to be passed over the guidewire, the introducer lumen including a staging chamber configured to receive an absorbable sponge pledget and a delivery chamber;a plunger having a lumen for allowing the plunger to be passed over the guidewire, the plunger insertable into the introducer for ejection of the pledget from the delivery chamber into a patient to seal a puncture in a blood vessel wall; andthe staging chamber having a first diameter, the delivery chamber having a second diameter smaller than the first diameter, and a tapered section being positioned between the staging chamber and the delivery chamber for compressing the pledget from the introducer into the delivery chamber.
