Beschreibung
Zusammenfassung:	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, or in prostatic tissue. Applications include renal denervation for the treatment of hypertension, atrial fibrillation, congestive heart failure, tissue ablation for COPD, BPH and prostate cancer and prevention of restenosis after balloon angioplasty or stent implantation and other disorders.
