摘要： 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.

摘要： 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. The method includes the steps of aligning guide means (12,28) in axial alignment with the puncture, mounting the sealing assembly (30) for movement along the guide means (12,28), and moving at least one of the sealing assembly (30) and guide means (12,28) until a transverse shoulder (20,36) encounters increased resistance to movement toward the blood vessel (16) by reason of engaging the exterior surface (40) of the blood vessel ( 16).
摘要翻译：一种用于在侵入性医疗程序之后密封血管（16）中的穿刺孔（17）的经皮血管密封组件（30）。密封组件包括具有承载电外科密封组件（34）的远端（36）的细长管状轴（32）。能量源组件（38）连接到密封组件（34）以使穿刺部位能够止血。提供了一种用于在医疗程序之后经皮定位密封组件（30）在穿刺（17）处与血管（16）基本上直接接合的相关方法。该方法包括以下步骤：使引导装置（12,28）与穿刺轴向对准，安装密封组件（30）以沿着引导装置（12,28）移动，并移动至少一个密封组件 30）和引导装置（12,28），直到由于接合血管（16）的外表面（40）而使横向肩部（20,36）遇到对血管（16）移动的阻力增加。
