Abstract: Devices and methods for mapping tissue, such as cardiac tissue, and applying electrical energy to ablate the tissue may include an applicator region comprising two or more wire electrodes that extend between the arms of the device as well as a plurality of mapping and/or sensing electrodes (e.g., ring electrodes) on the arms and/or the elongate body. These devices may sense electrical activity using the mapping electrodes and may deliver energy between the first wire electrode and the second wire electrode to ablate, for example, cardiac tissue.

Abstract: Systems and related methods for identifying and/or ablating targeted nerves are provided. A probe with stimulating electrodes and/or ablation members are provided. The probe may be inserted into a nasal cavity and current may be introduced through the electrodes to stimulate a targeted area. The response to stimulation may be used to identify the targeted nerve. Once identified, the ablation member may ablate the targeted nerve.

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.

Abstract: In an example, a cryotherapy system includes a base station, a cryotherapy applicator, and a cryogen conduit configured to couple the cryotherapy applicator to the base station and supply a cryogen from the base station to the cryotherapy applicator. The base station includes a housing including a canister receptacle that is configured to receive a canister containing the cryogen. The cryotherapy applicator includes a handle, a shaft extending from the distal end of the handle, and an end-effector coupled to the shaft. The end-effector is configured to use the cryogen to ablate a target tissue. An entirety of the cryotherapy applicator is movable relative to an entirety of the base station while the cryogen conduit couples the cryotherapy applicator to the base station.
