Abstract

A blood flow cessation device includes a catheter, an expandable member, and a rapid exchange port. The catheter includes a distal end portion and a proximal end portion. The expandable member is positioned at the distal end portion and is selectively expandable to stop blood flow through a vessel. The rapid exchange port is formed in the catheter at a location proximal of the expandable member. The rapid exchange port is configured receive a guidewire that passes through the distal end portion of the catheter to be positioned within the vessel.

Claims

1. A blood flow cessation device, comprising:

a catheter having a distal end portion and a proximal end portion;

an expandable member positioned at the distal end portion and being selectively expandable to stop blood flow through a vessel;

a rapid exchange port formed in the catheter at a location proximal of the expandable member, the rapid exchange port being configured to receive a guidewire that passes through the distal end portion of the catheter to be positioned within the vessel.

2. The blood flow cessation device of claim 1, further comprising a guidewire lumen extending from the rapid exchange port distally through the distal end portion of the catheter.

3. The blood flow cessation device of claim 1, wherein the expandable member comprises an inflatable balloon, and the catheter includes an inflation lumen that extends from the proximal end portion to the expandable member.

4. The blood flow cessation device of claim 3, further comprising a valve positioned at the proximal end portion and operable to control flow of inflation fluid relative to the inflation lumen.

5. The blood flow cessation device of claim 4, wherein the valve comprises one of a duckbill valve and a Tuohy Borst valve.

6. The blood flow cessation device of claim 1, wherein the expandable member comprises a shape memory material.

7. The blood flow cessation device of claim 6, wherein the expandable member comprises a Nitinol mesh positioned in an elastic membrane.

8. The blood flow cessation device of claim 1, further comprising a manifold positioned at the proximal end portion, the manifold being sized to pass through an introducer sheath.

9. The blood flow cessation device of claim 1, wherein the rapid exchange port is formed in a sidewall of the catheter.

10. A blood flow cessation system, comprising:

a blood flow cessation device comprising;

a catheter having a distal end portion and a proximal end portion;

an expandable member positioned at the distal end portion;

a rapid exchange port formed in the catheter at a location proximal of the expandable member and distal of the proximal end portion;

a treatment device;

a guidewire extending through the rapid exchange port and through the distal end portion;

wherein the blood flow cessation device is configured to advance along the guidewire through a vessel puncture and into a vessel where the expandable member is expandable to limit blood flow in the vessel, and the treatment device is configured to advance along the guidewire to the vessel puncture.

11. The blood flow cessation system of claim 10, further comprising an insertion sheath positionable in the vessel puncture, the blood flow cessation device being insertable through the insertion sheath into the vessel.

12. The blood flow cessation system of claim 11, wherein the insertion sheath is configured to be withdrawn over the blood flow cessation device prior to advancing the treatment device over the guidewire through the vessel puncture.

13. The blood flow cessation system of claim 10, wherein the treatment device comprises a large bore closure device.

14. The blood flow cessation system of claim 10, wherein the expandable member comprises an inflatable balloon and the catheter includes an inflation lumen coupled in flow communication with the inflatable balloon.

15. The blood flow cessation system of claim 10, wherein the catheter further comprises a guidewire lumen extending from the rapid exchange port through the distal end portion of the catheter.

16. A method of treating a vessel having a vessel puncture, the method comprising:

providing a blood flow cessation device, a guidewire, and a treatment device, the blood flow cessation device comprising a catheter having distal and proximal end portions, an expandable member, and a rapid exchange port positioned proximal of the expandable member and distal of the proximal end portion;

advancing the guidewire through the vessel puncture and into the vessel;

advancing the blood flow cessation device along the guidewire and into the vessel with the guidewire extending through the rapid exchange port;

operating the expandable member to limit blood flow through the vessel;

advancing the treatment device along the guidewire through the vessel puncture;

treating the vessel with the treatment device.

17. The method of claim 16, further comprising providing an insertion sheath, and inserting the insertion sheath through the vessel puncture, the guidewire extending through the insertion sheath.

18. The method of claim 17, wherein advancing the blood flow cessation device includes advancing the blood flow cessation device through the insertion sheath.

19. The method of claim 18, further comprising withdrawing the insertion sheath proximally along the blood flow cessation device prior to advancing the treatment device along the guidewire.

20. The method of claim 16, wherein operating the expandable member includes delivering a volume of inflation fluid through the catheter to expand the expandable member.

21. The method of claim 16, wherein treating the vessel includes at least partially closing the vessel puncture.
