Apparatus and method for treating rhinitis
First Claim
1. A method for treating rhinitis of a patient, the method comprising:
- visualizing a tissue region of a lateral nasal wall located within a nasal cavity of the patient;
inserting a distal end of a surgical probe into a sub-mucosal space of the lateral nasal wall of the patient, the surgical probe comprising a surgical probe shaft with a proximal end and the distal end, a handle coupled to the proximal end, a cryo-ablation element disposed on the distal end, and a position indicator disposed in the vicinity of the distal end;
advancing the distal end of the surgical probe shaft within the lateral nasal wall tissue region and towards at least one posterior nasal nerve associated with the lateral nasal wall tissue region while visually tracking a position of the distal end with the position indicator; and
cryogenically ablating the at least one posterior nasal nerve with the cryo-ablation element to reduce at least one symptom of rhinitis.

Abstract
Devices and methods for treating rhinitis are described where the devices are configured to ablate a single nerve branch or multiple nerve branches of the posterior nasal nerves located within the nasal cavity. A surgical probe may be inserted into the sub-mucosal space of a lateral nasal wall and advanced towards a posterior nasal nerve associated with a middle nasal turbinate or an inferior nasal turbinate into a position proximate to the posterior nasal nerve where neuroablation of the posterior nasal nerve may be performed with the surgical probe. The probe device may utilize a visible light beacon that provides trans-illumination of the sub-mucosal tissue or an expandable structure disposed in the vicinity of the distal end of the probe shaft to enable the surgeon to visualize the sub-mucosal position of the distal end of the surgical probe from inside the nasal cavity using, e.g., an endoscope.
