Abstract

A vessel puncture closure device includes a balloon catheter and a sealant delivery device. The balloon catheter has an inflatable balloon positioned at a distal end thereof. The sealant delivery catheter has a sealant lumen configured to delivery a volume of sealant to a vessel puncture. The sealant delivery catheter is configured to move axially relative to the balloon between a first position in which the sealant delivery catheter delivers a first volume of sealant to the vessel puncture, and a second position spaced proximal of the first position to deliver a second volume of sealant to the vessel puncture.

First claim

What is claimed is:

1. A vessel puncture closure device, comprising:
a sheath;
a balloon catheter extending through the sheath, the balloon catheter having an inflatable balloon positioned at a distal end thereof;
a sealant delivery catheter extending through the sheath, the sealant delivery catheter having a plurality of internal sealant delivery lumens, the plurality of internal sealant delivery lumens configured to deliver a volume of sealant to a vessel puncture, the plurality of internal sealant delivery lumens each having a distal end, at least two of the distal ends having different longitudinal positions along the sealant delivery catheter;
a carriage assembly comprising a latch and a base, the latch being longitudinally aligned with the balloon catheter and the sealant delivery catheter, the latch being configured to provide temporary attachment of the base to the sheath;
wherein the sealant delivery catheter is configured to move axially relative to the inflatable balloon, the sheath, and the base between a first position in which the sealant delivery catheter delivers a first volume of sealant to the vessel puncture, and a second position spaced proximal of the first position to deliver a second volume of sealant to the vessel puncture.

2. The vessel puncture closure device of claim 1 , further comprising a retraction device interposed between the balloon catheter and sealant delivery catheter to move the sealant delivery catheter between the first and second positions.

3. The vessel puncture closure device of claim 2 , wherein the retraction device includes an activator, which when operated causes the retraction device to automatically move the sealant delivery catheter between the first and second positions.

4. The vessel puncture closure device of claim 2 , wherein the retraction device includes a biasing member, and releasing the biasing member moves the sealant delivery catheter between the first and second positions.

5. The vessel puncture closure device of claim 2 , further comprising a sealant source coupled in flow communication with the sealant delivery catheter, and operating the sealant source to deliver one of the first and second volumes of sealant operates the retraction device.

6. The vessel puncture closure device of claim 5 , wherein the sealant source comprises a syringe having a plunger, and operating the plunger to eject at least one of the first and second volumes of sealant into the sealant delivery catheter operates the retraction device.

7. The vessel puncture closure device of claim 2 , wherein the balloon catheter comprises a housing, and the retraction device is mounted to the housing.

8. The vessel puncture closure device of claim 1 , wherein the sealant delivery catheter includes a distal sealant opening spaced a first predetermined distance from the inflatable balloon in the first position and spaced a second predetermined distance from the inflatable balloon in the second position.

9. The vessel puncture closure device of claim 1 , wherein the sealant delivery catheter is advanced over the balloon catheter to the vessel puncture.

10. The vessel puncture closure device of claim 1 , further comprising a detachable sealing tip positioned at a distal end of the balloon catheter distal of the inflatable balloon, the detachable sealing tip being detachable within the first volume of sealant upon removal of the balloon catheter from the vessel puncture.

11. A tissue puncture closure device, comprising:
a sheath;
a first catheter extending through the sheath, the first catheter having a balloon positioned at a distal end thereof, the first catheter being insertable through a tissue puncture and configured to inflate the balloon to temporarily seal the tissue puncture internally;
a second catheter extending through the sheath, the second catheter being configured to advance over the first catheter to the tissue puncture, the second catheter having a plurality of sealant delivery lumens, the plurality of sealant delivery lumens being configured to deliver a volume of sealant to seal the tissue puncture externally, the plurality of sealant delivery lumens each having distal openings positioned at different longitudinal positions on the second catheter;
a retraction device having a carriage assembly, a latch, and a base, the latch providing temporary attachment of the base to the sheath, the second catheter being mounted to the carriage assembly, the retraction device being operable between the first and second catheters to automatically move a distal opening of the second catheter relative to the sheath between a first axial position relative to the balloon and a second axial position spaced further from the balloon than the first axial position, the carriage assembly being configured to guide longitudinal movement of the second catheter relative to the base between the first and second axial positions.

12. The tissue puncture closure device of claim 11 , wherein the retraction device further comprises a trigger operable to actuate the retraction device.

13. The tissue puncture closure device of claim 11 , further comprising a sealant source configured to deliver a first volume of sealant to the tissue puncture when the distal opening is in the first axial position, and to deliver a second volume of sealant to the tissue puncture when the distal opening is in the second axial position.

14. The tissue puncture closure device of claim 13 , wherein operating the sealant source actuates a trigger.

15. The tissue puncture closure device of claim 13 , wherein the sealant source operates to provide a continuous flow of the first and second volumes of sealant.
