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 comprising a sheath wall that surrounds and forms a guide insertion lumen, the sheath instrument extending along a longitudinal axis from a proximal portion to a distal portion, the sheath instrument comprising a balloon coupled to the distal portion, wherein a drain lumen extends through at least a portion of the balloon or sheath instrument;
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 lumen extending from the proximal portion along the longitudinal axis and further extending radially away from the longitudinal axis toward the sheath wall and terminating at a guide insertion port that extends through a balloon wall of the balloon to, in use, face an inner wall of the blood vessel;
advancing the guide instrument through 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.

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.

18. 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, wherein the medical procedure comprises renal plexus denervation or a renal neuroplexus diagnostic procedure. - View Dependent Claims (19, 20)
