Abstract
A system for facilitating hemostasis of a puncture site in a blood vessel delivers an absorbable sponge pledget in a hydrated state to a position at an exterior of the blood vessel puncture to facilitate hemostasis. The system includes a staging chamber, a delivery cannula, and a pusher. The staging chamber is used for hydrating a pledget of absorbable sponge, compressing the pledget, and delivering the pledget to the delivery cannula. The staging chamber may include a valve for facilitating hydration and staging of the pledget. The delivery cannula and pusher are used to accurately place the sponge pledget outside the blood vessel. An easy loader connector may be used to facilitate loading the dry pledget into the staging chamber.
