Abstract: Devices and methods for more effective cryoablation of a posterior nasal nerve. The cryoablation tip of the device is paddle-shaped, with broad, flat, overall rectangular outline with notches on the sides to create a metacentric outline. One side of the cryoablation tip is conductive, while the opposing side is highly non-conductive. Corner portions of the tip are also non-conductive. Intermediate portions of the side-edge surfaces conductive, and are configured as recesses or notches in the side edge. In use, the system will be inserted into the nasal cavity of a patient, with conductive surfaces of the cryoablation tip disposed in contact with portions of the turbinate lining overlying a posterior nasal nerve, and operated to cool those portions to ablate the posterior nasal nerve. The insulative portion of the cryoablation tip protects remaining surrounding tissue from cryoablation.
