Systems, devices, and methods for treatment of nasal disorders

Abstract

Systems, devices, and methods involve ablation of tissue to treat rhinitis and/or other nasal conditions. Implementations allow treatment of tissue in the confined space of the nasal cavity. Additionally, implementations allow targeted treatment tissue to be ablated, while protecting other non-treatment tissue from unintentional collateral effects that might be produced by the ablation. According to an example implementation, an approach for treating a nasal condition includes advancing a probe into a nasal cavity, the probe including a shaft and a cryotherapy element coupled to the shaft. The approach also includes cryogenically cooling a target treatment site with the cryotherapy element to treat at least one nasal nerve. Additionally, the approach includes transmitting a focused ultrasound beam to a target heating site to increase a temperature tissue at the target heating site.
