Vascular sealing apparatus and method
First Claim
1. A method for closing a puncture or other opening in a blood vessel, comprising the steps of:
- (a) inserting a balloon apparatus through an introducer which is disposed in the blood vessel opening;
(b) inflating said balloon apparatus;
(c) moving said balloon apparatus into contact with the opening sufficient to effect a hemostatic seal at the puncture site;
(d) introducing a procoagulant to the opening;
(e) deflating said balloon apparatus; and
(f) removing said balloon apparatus through the opening and through the procoagulant.

Abstract
A vascular sealing device for effecting closure of a puncture or other opening in a blood vessel, or other body cavity, which has been entered through percutaneous techniques. The device is useable with a standard percutaneous vascular introducer. The vascular sealing device generally comprises a body or shaft, an adapter disposed at a proximal end of the shaft, and a balloon portion disposed generally at a distal end of the shaft. A core wire is connected to the distal end and extends, internally, through a lumen of the device for deflation of the balloon. A procoagulant is introduced through the introducer, or alternatively through an additional lumen and associated apertures, and to the puncture sealed by the inflated balloon. Subsequently, the balloon is deflated and the device is removed from the sealing puncture, with or without the aid of a reaccess sheath.

12. A method for rapid closure of a puncture or other opening in a blood vessel, comprising the steps of:
-
(a) inserting a balloon apparatus through an introducer which is displaced in the blood vessel opening; (b) inflating said balloon apparatus; (c) moving said balloon apparatus into contact with the opening sufficient to effect a hemostatic seal at the puncture site; (d) introducing a procoagulant to the opening by injection through the introducer as the introducer is retracted, and then commencing deflation of said balloon apparatus so that the procoagulant is injected, the introducer is retracted, and the balloon deflation is commenced within a time period of between about one and three minutes; (e) deflating said balloon apparatus; and (f) removing said balloon apparatus through the opening. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
