<p>This invention is a vascular sealing device (10) for effecting closure of a puncture or other opening in a blood vessel (56), or other body cavity, which has been entered through percutaneous techniques. The device is useable with a standard percutaneous vascular introducer (51). The vascular sealing device generally comprises a body or shaft (13), an adapter (14) disposed at a proximal end of the shaft (13), and a balloon portion (15) is disposed generally at a distal end of the shaft (13). A core wire (17) is connected to the distal end and extends, internally, through a lumen (18) of the device (10) for deflation of the balloon (15). A pro-coagulant is introduced through the introducer (51), or alternatively through an additional lumen (8) and associated apertures (81), and to the puncture sealed by the inflated balloon (15). Subsequently, the balloon (15) is deflated and the device is removed from the sealing puncture, with or without the aid of a re-access sheath (49).</p> |
