Abstract
An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and/or nerve fibers in the outer layer or deep to the outer layer of the vessel. A method of treating hypertension involves injecting an ablative fluid such as ethanol deep into zones in the wall of the renal artery such that the zones of fluid merge to form a circumferential ablation ring at a depth which ablates sympathetic nerves while minimizing injury to interior layers of the vessel wall.
