The method, device and system for electrical sealing of a puncture opening in a blood vessel wall. In a first embodiment, a vascular sealing probe has two bipolar electrodes formed thereon, is insertable to a position whereat the bipolar tip is adjacent the blood vessel puncture site to effect electrocauterization or electrocoagulation of the puncture site. In a second embodiment the bipolar vascular sealing probe has a first electrode formed thereon and an electrode-guide wire has the second bipolar electrode formed thereon. The electrode-guide wire is passable through a lumen formed in the probe such that the second electrode on the electrode-guide wire is positioned close enough to the first electrode positioned on the probe to permit electrical current to pass therebetween.

1. A bipolar vascular sealing probe device for sealing a puncture in a blood vessel comprising the combination of:a) a probe comprising: an elongate probe body having a proximal end, a distal end and a guide wire passage lumen extending through at least a portion of said probe body; a first bipolar electrode formed on said probe body comprising an electrically conductive member positioned near the distal end of said probe body and having a distal face portion which is concave; a first conduction pathway extending longitudinally through said probe to carry electrical current from the proximal end of said probe body to said first bipolar electrode; and b) an electrode-guide wire device comprising: an elongate guide wire having a proximal end, a distal end and an outer surface; a second bipolar electrode formed on a discrete distal region of the outer surface of said guide wire; a second conduction pathway extending longitudinally through said guide wire to carry electrical current to said second bipolar electrode formed thereon; wherein said guide wire being passable through the guide wire passage lumen of said probe such that a portion of said guide wire protrudes out of said guide wire passage lumen, and further such that said second bipolar electrode is located in sufficient proximity to said first bipolar electrode such that electrical current may pass between said first bipolar electrode and said second bipolar electrode.
