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 producer sheath which is already in place within a tissue tract. The 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.

Claims3

Dependent claims

A system for determining a location of a blood vessel puncture for delivery of a hemostasis promoting material to the blood vessel puncture to facilitate hemostasis, the system comprising:

an introducer sheath having a lumen, a proximal end, and a distal end configured to be inserted into a blood vessel puncture;
a hemostasis promoting material delivery system having a connector for forming a fluid tight connection with the proximal end of the introducer sheath;
a bleed back exhaust tube having a first end in fluid communication with the lumen of the introducer sheath and a second end positioned to deliver blood to an exterior of the system to provide a visual indication of the location of the distal end of the introducer sheath, wherein the bleed back exhaust tube has an inner diameter of less than 2 mm and, wherein the bleedback exhaust tube is on the hemostasis promoting material delivery system.

Dependencies are inferred from the claim text.
