System and method for delivering hemostasis promoting material to a blood vessel puncture with a staging tube
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.
1. A system for delivering hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
an introducer sheath having a distal end;
a hydration chamber coupled to said introducer sheath;
a control tip coupled to said hydration chamber and having a distal tip adapted to locate the puncture; and,
a staging tube having a distal end located distally of the distal end of said introducer sheath and at a predetermined distance proximally of the distal tip, the predetermined distance being sufficient for receiving the hemostasis promoting material.
2. The system of claim 1 , wherein the control tip has a proximal end extending through a side of the hydration chamber between the proximal and distal ends of the hydration chamber.
3. The system of claim 1 , wherein the control tip has a central lumen extending from a distal end to a proximal end of the control tip configured to receive a guidewire.
4. The system of claim 1 , wherein an enlarged distal tip of the control tip extends beyond the distal end of the introducer sheath when the distal end of the hydration chamber is engaged with the proximal end of the introducer sheath.
5. The system of claim 1 , wherein the hydration chamber has a first inner diameter, a second inner diameter, and a tapered portion between the first and second inner diameters for compressing the hemostasis promoting material.
6. The system of claim 5 , wherein the second inner diameter is substantially the same as an inner diameter of the introducer sheath.
7. A system for delivering hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
an introducer sheath having a distal end;
a hydration chamber coupled to said introducer sheath;
a control tip including a tube having a first diameter and an enlarged distal tip having a second diameter larger than the first diameter; and,
a staging tube having a distal end located between the distal end of said sheath and said enlarged distal tip of the control tip.
8. A system for delivering hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
an introducer sheath having a distal end;
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;
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; and,
a staging tube having a distal end located between said distal end of said sheath and said enlarged distal tip of the control tip.
9. A system for delivering hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
an introducer sheath having a distal end, said introducer sheath having a distal taper so that the introducer sheath has a first inside diameter proximal of said distal taper and a second inside diameter at said distal taper;
a hydration chamber coupled to said introducer sheath; and,
a control tip coupled to said hydration chamber, wherein the diameter of said control tip is greater than the second inside diameter.
10. A process for delivering hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, using an introducer sheath having a distal end and a staging tube having a distal end, the process comprising:
locating a puncture locator at a predetermined distance distally with respect to the staging tube distal end;
locating the distal end of said staging tube distally of the distal end of said introducer sheath; and,
delivering the hemostasis promoting material through said introducer sheath and staging tube after the puncture locator has located the puncture.
