    摘要： A cryoablation tool may include a catheter. The catheter may have a shaft having: a proximal end, a distal end, a shaft wall extending between the proximal end and the distal end, the shaft wall having an outer surface and an inner surface and a vacuum gap defined therebetween that forms a vacuum chamber, the inner surface of the shaft wall being gas permeable, a shaft lumen bounded by the inner surface of the shaft wall, the shaft lumen for carrying a cryogen gas, and the vacuum chamber having a proximal opening connectable to a vacuum source, the proximal opening establishing vacuum communication between the vacuum chamber and the vacuum source.

    摘要： Devices, systems, and methods for quantifying applied pressure by a device against an area of tissue. In particular, the present technology is related to medical devices including an optical element with a fiber Bragg grating, systems including the medical devices, and methods of quantifying applied pressure by the medical device. In one embodiment, a medical device comprises an elongate body including a distal portion and a proximal portion opposite the distal portion, and an optical element located at the distal portion of the elongate body. In one embodiment, the optical element include an optical fiber with a fiber Bragg grating. In one embodiment, the medical device is part of a medical system comprising a control unit in communication with the medical device, the control unit including an optical interrogator in communication with the optical element and processing circuitry configured to receive data from the optical interrogator.

    摘要： Cryotherapeutic devices for targeted lunch neuromodulation therapies and associated systems and methods are disclosed herein. A cryotherapeutic device configured in accordance with embodiments of the present technology can include, for example, an elongated shaft having a distal portion and a cooling assembly positioned at the distal portions. The shaft is configured to deliver the distal portion at a target site within a bronchus of a patient. The cooling assembly includes an expandable member, an injection lumen configured to dispel a refrigerant into the expandable member, and an exhaust lumen configured to receive expanded refrigerant. The cooling assembly is configured to impart cryogenic cooling to ablate neural fibers proximate to the target site. The device can be sized to fit within a working channel of a bronchoscope such that at least a portion of the cooling assembly can be visualized during a cryotherapeutic procedure.
