Arteriotomy closure devices and techniques
First Claim
1. A method of closing an opening in a blood vessel, the method comprising:
- providing a vessel closure device comprising an electrically conductive material;
advancing the vessel closure device percutaneously to an opening in a vessel to mechanically draw together sides of the opening or occlude the opening;
connecting a power source to said electrically conductive material;
providing electrical power to the electrically conductive material via the power source to thereby heat tissue in an area near the opening to facilitate the closure or healing of the opening,wherein advancing the vessel closure device comprises;
introducing a tubular medical device into the opening in the vessel; and
advancing the vessel closure device over the tubular medical device until the vessel closure device is near or contacts the vessel,wherein advancing the vessel closure device over the tubular medical device comprises utilizing a deployment device separate from said tubular medical device,wherein said step of utilizing a deployment device comprises mounting the deployment device to the tubular medical device before or after the tubular medical device has been inserted into the body, andwherein said deployment device is mounted to the tubular medical device using a longitudinal slot in said deployment device.

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.
