Abstract: A cutting device is described having a base with an opening with cutting edges, and a flap articulated with respect to the base, the flap having a shape corresponding to the opening and cutting edges corresponding to the cutting edges of the opening. The cutting device is preferably provided as part of a kit for preparing and delivering hemostatic material to a patient.
Abstract: 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.

Abstract: A system for delivering hemostasis promoting material of the present invention allows the hemostasis promoting material to be delivered to a blood vessel puncture site by fluid pressure. The system allows the hemostasis promoting material to be delivered through an introducer sheath which is already in place within a tissue tract. This system includes a control tip which is insertable through the introducer sheath to locate and occlude the blood vessel puncture site and a hydration chamber for receiving and delivering the hemostasis promoting material to the blood vessel puncture site. The system accurately locates the blood vessel wall at a puncture site and for properly placing a hemostasis plug over the puncture site.

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.
