  • Publication number: 20230314268
    Abstract: Apparatus and methods for treating conditions such as rhinitis are disclosed herein where a distal end of a probe shaft is introduced through the nasal cavity where the distal end has an end effector with a first configuration having a low-profile which is shaped to manipulate tissue within the nasal cavity. The distal end may be positioned into proximity of a tissue region having a post nasal nerve associated with a middle or inferior nasal turbinate. Once suitably positioned, the distal end may be reconfigured from the first configuration to a second configuration which is shaped to contact and follow the tissue region and the post nasal nerve may then be ablated via the distal end. Ablation may be performed using various mechanisms, such as cryotherapy, and optionally under direct visualization.

  • Publication number: 20230248411
    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.

  • Patent number: 11622689
    Abstract: A method of imaging a tissue region may comprise visualizing lesions over a tissue region via an imaging catheter by viewing the tissue region through a viewing region purged by a fluid and identifying, with a computer, a location of each of the lesions relative to one another over the tissue region. The method may also include registering, with the computer, a unique set of ablation parameters received from a treatment device for lesion generation for each of the lesions and generating, with the computer, a map of the lesions based on the identified locations of the lesions. The method may also include visually displaying the map of the lesions in a common display with a real-time field of view image of a first lesion; and visually displaying the registered unique set of ablation parameters for the first lesion with the real-time field of view image of the first lesion.
