Abstract

A system for conducting denervation of the neural plexus adjacent the renal artery, comprises a pre-shaped ablative element operatively coupled to an elongate deployment member configured to be navigated into the renal artery, the pre-shaped ablative element comprising one or more RF electrodes disposed in an arcuate pattern; and an energy source operatively coupled to the one or more RF electrodes and being configured to cause current to flow from the pre-shaped ablative element and cause localized heating sufficient to denervate nearby neural tissue.

Claims

1. A method for performing a medical procedure using a robotic catheter system, the method comprising:

advancing, within a blood vessel of a patient, a sheath instrument having a balloon coupled to a distal portion of the sheath instrument, wherein a drain lumen extends through at least a portion of the balloon member or sheath instrument, and wherein a guide insertion lumen extends through the sheath instrument and terminates at a guide insertion port that extends through the balloon;

inflating the balloon, wherein following inflation, blood flow of the blood vessel continues through the drain lumen;

advancing a guide instrument through the guide insertion lumen, the guide insertion port, and a wall of the blood vessel to create a transvascular access port;

advancing the guide instrument and a diagnostic or interventional instrument to a target site to perform a medical procedure; and

retracting the guide instrument and the diagnostic or interventional instrument and closing the transvascular access port prior to deflation of the balloon and removal of the sheath instrument.

2. The method of claim 1, wherein the medical procedure comprises renal plexus denervation or a renal neuroplexus diagnostic procedure.

3. The method of claim 1, wherein the blood vessel is selected from a group consisting of the patient'"'"'s:

celiac trunk artery, superior mesentary artery, vena cava, and renal vein.

4. The method of claim 1, wherein the drain lumen extends through at least a portion of the sheath instrument.

5. The method of claim 1, wherein the drain lumen extends through at least the balloon.

6. The method of claim 1, wherein an outlet of the guide insertion port is positioned on a side of the balloon.

7. The method of claim 1, wherein the balloon is inflated until the blood vessel is occluded except for the blood flowing through the drain lumen.

8. The method of claim 1, further comprising advancing a tool through the guide insertion lumen, the guide insertion port, and the wall of the blood vessel.

9. The method of claim 8, wherein the tool comprises a needle, wire, or dilator.

10. The method of claim 9, wherein the guide instrument is advanced over the tool using a working lumen of the guide instrument in an over-the-wire technique.

11. The method of claim 1, wherein advancing the sheath instrument and advancing the guide instrument are performed robotically by the robotic catheter system.

12. The method of claim 1, wherein advancing the diagnostic or interventional instrument is performed robotically by the robotic catheter system.

13. The method of claim 1, wherein the sheath instrument and guide instrument are steerable catheters.

14. The method of claim 1, wherein the diagnostic or interventional instrument is coupled to the guide instrument.

15. The method of claim 1, wherein the diagnostic or interventional instrument comprises a radiofrequency electrode, a cryoablation reservoir, a high intensity focused ultrasound treatment transducer, or a laser.

16. The method of claim 1, wherein closing the transvascular access port comprises closing the transvascular access port with a closure clip.

17. The method of claim 1, further comprising tracking a position or shape of a distal portion of at least one of the sheath instrument and the guide instrument using a localization system.
