Abstract
A vascular closure system includes a vessel closure device with an electrically conductive component. The vessel closure device is configured to be advanced percutaneously to an opening in a blood vessel and to mechanically draw together sides of the opening or occlude the opening. A power source in electrical contact with the vessel closure device provides power to the vessel closure device to thereby heat tissue in an area near the opening to facilitate the closure or healing of the opening. The vessel closure device may be configured to be advanced to the opening over a tubular medical device. The vessel closure device may include a superelastic or shape memory element. The vessel closure device may be in contact with two conductors from the power source and may be configured to heat tissue via direct resistive element heating. Alternatively, one conductor may be connected to the vessel closure device and a second conductor may be connected to a ground pad on the patient.
