1. A method for closing a large penetration in an arterial wall at the end of a tissue tract formed from a skin surface of the patient to the arterial wall, 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 large penetration temporarily sealed by the occlusion element such that the sealant is disposed within the tissue tract to promote hemostasis of the tissue tract.
