System and method for delivering hemostasis promoting material to a blood vessel puncture site by fluid pressure
First Claim
1. A system for delivering hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
- an introducer sheath having a proximal end and a distal end configured to be inserted into a blood vessel puncture;
a hydration chamber configured to receive and hydrate a pledget of hemostasis promoting material, the hydration chamber having a distal end configured to be connected to the proximal end of the introducer sheath and a proximal end configured to be connected to a syringe; and
a control tip including a tube having a first diameter and an enlarged distal tip having a second diameter larger than the first diameter, the tube configured to extend from an interior of the hydration chamber through the distal end of the hydration chamber, through the introducer, and out the distal end of the introducer.

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 controlled 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.
