1. A method of treating epistaxis, the method comprising:
(a) inserting a distal end of an endoscope into a nasal cavity of a patient, wherein at least the distal end of the endoscope includes a working channel and a distal tip, wherein the endoscope defines a tubular perimeter;
(b) advancing a distal end of a radiofrequency (RF) ablation catheter through the working channel of the endoscope, wherein the distal end of the RF ablation catheter includes a distal tip;
(c) arresting advancement of the RF ablation catheter while the distal tip of the RF ablation catheter is positioned at the distal tip of the endoscope and while the distal tip of the RF ablation catheter is radially positioned within the tubular perimeter defined by the endoscope; and
(d) ablating tissue in a posterior nasal region of the nasal cavity using RF energy transmitted by the RF ablation catheter while the distal tip of the RF ablation catheter is positioned at the distal tip of the endoscope and while the distal tip of the RF ablation catheter is radially positioned within the tubular perimeter defined by the endoscope.
