Devices for therapeutic nasal neuromodulation and associated systems and methods are disclosed herein. A system for therapeutic neuromodulation in a nasal region configured in accordance with embodiments of the present technology can include, for example, a shaft and a therapeutic element at a distal portion of the shaft. The shaft can locate the distal portion intraluminally at a target site inferior to a patient's sphenopalatine foramen. The therapeutic element can include an energy delivery element configured to therapeutically modulate postganglionic parasympathetic nerves at microforamina of a palatine bone of the human patient for the treatment of rhinitis or other indications. In other embodiments, the therapeutic element can be configured to therapeutically modulate nerves that innervate the frontal, ethmoidal, sphenoidal, and maxillary sinuses for the treatment of chronic sinusitis.

FOCUSED TREATMENT TIP DESIGN AND METHOD TO OPTIMIZE HEAT TRANSFER THROUGH LOW TEMPERATURE FLUIDS AND GASES

A focused treatment tip (FTT) for controlling the evaporation rate and providing targeted delivery of low temperature liquified gases for contact with living tissue includes a contoured body. When filled with liquified gas, the device insulates the gas from waste heat sources, such as the surrounding environment. The device can control the evaporation rate of the liquified gas at the treatment site. The controlled evaporation rate affects the rate of heat transfer from the treated tissue allowing for controlled exposure times and desired outcomes. The device can be used with various application tips to further define the target tissue area to be treated while minimizing collateral damage to surrounding tissue and isolating the gas within the contoured body and focusing heat transfer to the desired treatment area. The device may use transparent materials that make the treatment visible to the operator while the liquified gas is evaporating.

ELECTROSURGICAL INSTRUMENT FOR FREEZING AND ABLATING BIOLOGICAL TISSUE

An electrosurgical instrument for applying microwave energy to biological tissue, where the instrument is capable of freezing biological tissue in a region around a radiating tip portion and applying microwave energy to the frozen tissue. By freezing the region around the radiating tip portion, microwave energy radiated from the radiating tip portion can be transmitted through the frozen region with low losses and into tissue surrounding the frozen region. This enables the size of the treatment area to be increased without having to increase the amount of microwave energy delivered to the radiating tip portion. The instrument comprises a transmission line, a radiating tip, a fluid feed for conveying a tissue-freezing fluid, and a thermal transfer portion arranged to provide thermal communication between the tissue-freezing fluid and biological tissue in a treatment zone.
