SYSTEM AND METHOD FOR ENDOLUMINAL AND TRANSLUMENAL THERAPY

摘要

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.

主权项

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.
