Abstract
A vascular closure device seals a vascular access site upon completion of a procedure wherein a blood vessel has been punctured to accommodate a guidewire, an introducer sheath, and other intravascular devices. The device uses compression and thermal heating of an area around the puncture to obtain immediate hemostasis. Electrothermal bipolar vessel sealing is preferably employed, wherein a forceps grasps and compresses tissue from opposite sides of the puncture and then applies a high-frequency alternating electric current to cause the vessel wall between the forceps to denature and seal.
