  • Patent number: 11178496
    Abstract: Methods and apparatus for transmitting vibrations via an electronic and/or transducer assembly through a tooth or teeth are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device. The electronic and transducer assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating transducer element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.

  • Publication number: 20210268243
    Abstract: In an example, a method for delivery of a therapeutic agent to at least one of a palatine canal or a pterygopalatine fossa of a patient is described. The method includes inserting a delivery device into a nasal cavity of a patient. The delivery device includes an elongated shaft with a proximal end and a distal end, a handpiece coupled to the proximal end of the elongated shaft, and a boring element disposed on the distal end of the elongated shaft. The method also includes advancing the distal end of the elongated shaft to a position proximate to a palatine bone within the nasal cavity, actuating the boring element to form a passage in the palatine bone between the nasal cavity and a palatine canal of the patient, and delivering a therapeutic agent into the palatine canal.

  • Publication number: 20210244458
    Abstract: The invention disclosed here generally relates to devices that can modify a property of a nerve. Specifically, the subject invention is contemplated to modify the posterior nasal nerve signal conduction in such a way so as to reduce the signals transmitted to the nasal cavity. Reduction or interruption of the nerve signals results in the reduction of the distal organ activity. In particular, embodiments of the present invention allow for increased lateral contact or apposition of the target tissue region having at least one posterior nasal nerve with the end effector surface by lateral and/or longitudinal translation of the end effector relative to the surgical probe shaft. This improved lateral surface contact has several benefits, including improved patient outcomes and patient safety as the end effector is adequately in contact with target tissue for subsequent ablation therapy.

  • Patent number: 11045341
    Abstract: Apparatus for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to a longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.

  • Publication number: 20210137610
    Abstract: The invention disclosed here generally relates to devices used to identify the location of a never in order to modify a property of the nerve. Specifically, the invention utilized pre-operative scans of a patient's nasal cavity in order to identify target treatment locations when a nerve to be treated is located. The image of the nasal cavity and target treatment location can be registered with the real time position of the nasal cavity using a surgical navigation system in order to assist in guiding a surgical probe to the target treatment location.

  • Patent number: 10772492
    Abstract: A method of inhibiting flow of a purging fluid from a device comprises positioning an imaging hood in proximity to a tissue region to be visualized. The imaging hood includes a distal membrane which defines a main aperture. The imaging hood and the distal membrane define an open area. The method also comprises introducing the purging fluid into a proximal portion of the open area. The proximal portion is bounded by a proximal membrane including a plurality of apertures. The method also comprises pressurizing the proximal membrane with the purging fluid to a partially extended state in which the purging fluid flows through the plurality of apertures and through the main aperture. The method also comprises pressurizing the proximal membrane with the purging fluid to a blocking extended state in which the proximal membrane obstructs the main aperture to block the flow of the purging fluid through the main aperture.
