Methods for renal nerve blocking
First Claim
Patent Images
1. A method for treatment of a human patient diagnosed with hypertension, the method comprising:
- positioning a catheter in a periarterial space of a renal artery and proximate a renal nerve of the patient; and
delivering a nerve blocking agent via the catheter to inhibit neural traffic along the renal nerve,wherein delivering the nerve blocking agent results in a therapeutically beneficial reduction in blood pressure of the patient.

Abstract
A method and apparatus for treatment of cardiac and renal diseases associated with the elevated sympathetic renal nerve activity by implanting a device to block the renal nerve signals to and from the kidney. The device can be a drug pump or a drug eluding implant for targeted delivery of a nerve-blocking agent to the periarterial space of the renal artery.

16. A method for catheter-based renal denervation of a hypertensive human patient, the method comprising:
-
positioning a catheter having a drug delivery element within a renal hilum of the patient and adjacent neural fibers innervating a kidney of the patient; and at least partially ablating the neural fibers via a nerve blocking agent delivered from the drug delivery element, wherein at least partially ablating the neural fibers results in a therapeutically beneficial reduction in blood pressure in the patient. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
