Abstract: 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.

Abstract: A percutaneous vascular sealing assembly (30) for sealing a puncture opening (17) in a blood vessel (16) following an invasive medical procedure. The sealing assembly includes an elongated tubular shaft (32) having a distal end (36) carrying an electrosurgical sealing assembly (34). An energy source assembly (38) is connected to the sealing assembly (34) to enable hemostasis of the puncture site. An associated method for percutaneous positioning of the sealing assembly (30) in substantially direct engagement with the blood vessel (16) at the puncture (17) following a medical procedure is provided.
