## Abstract

A system for sealing a large penetration in the wall of a femoral artery comprises an occlusion catheter and an applicator. An access catheter may further be provided in order to facilitate introduction of the occlusion catheter. The occlusion catheter is introduced through a contralateral penetration, advanced over the aortic bifurcation, and an occlusion element on the occlusion catheter is positioned at the large diameter penetration. The occlusion element is then inflated to temporarily seal the large penetration while blood perfusion past the occlusion element is provided by the catheter. A sealing material, such as a tissue adhesive or other hemostatic agent is then introduced into a tissue tract above the large diameter penetration in order to seal the penetration. The occlusion element may be left in place while the sealing material has time to set, cure or otherwise form a permanent seal of the large penetration. The occlusion catheter and all access sheaths may then be removed from the patient.

## Claims

### Claim 1

A method for closing a large penetration in an arterial wall at the end of a tissue tract, said method comprising:
advancing an occlusion catheter through a second penetration in the arterial wall to position an occlusion element on a luminal side of the large penetration;
deploying the occlusion element to temporarily seal the large penetration while allowing blood perfusion past the occlusion element; and
introducing a sealant into the tissue tract above the occluded large penetration.

### Claim 2

A system for sealing a large penetration in a wall of a first femoral artery at the end of a tissue tract, said system comprising:
an occlusion catheter having an occlusion element near a distal end thereof, said occlusion catheter adapted to be advanced through a penetration in a contralateral femoral artery, over an aortic bifurcation, and into the first femoral artery so that the occlusion element can be positioned and deployed to temporarily seal the large penetration; and
an applicator adapted to deliver a sealing material into the tissue tract.
