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.

A medical sealing apparatus for use in closing an opening in a blood vessel, comprising: (a) a body structure having a proximal and a distal end, said body structure timber having an elongated tubular shaft with proximal and distal ends, an adapter connected to said proximal end of said shaft, and a central lumen extending axially through said shaft and said adapter; (b) an inflatable member disposed adjacent said distal end of said shaft and communicatively connected to said lumen, said inflatable member having an inflated diameter and a deflated diameter which is less than that of said inflated diameter; (c) means to introduce a procoagulant to the blood vessel opening at a point proximally located with respect to said inflatable member; and (d) means, connected to said body structure, to longitudinally compress said inflatable member so that it assumes a predetermined configuration during an inflation and to longitudinally stretch said inflatable member so that it returns to said deflated diameter subsequent to an inflation.
