    摘要: A cryosurgery system for application of medical-grade liquid nitrogen to a treatment area via a small, low pressure, open tipped catheter. The system includes a console, including a touch panel computer, a cryogen module, a suction module and an electronics module, and a disposable spray kit. Features include optional low cryogen flow setting to reduce the cryogen flow rate by 50%, improved cryogen flow consistency reducing pressure pulses and peaks, an integrated suction pump for improved consistency and self-checks, specified vent tube areas and corresponding maximum expected pressures during cryospray procedure; optional pressure sensing capability to monitor pressure during a treatment, and novel catheter designs of multilayer and flexible construction providing a variety of spray patterns.

    摘要: A tip for application of cryogenic matter onto a skin lesion includes a conduit configured to receive therein cryogenic matter; an absorbent application element configured to absorb and contain the cryogenic matter from the conduit and having an exposed face configured to apply the cryogenic matter directly onto the skin lesion; a thermally conductive material arranged in contact with at least a portion of the absorbent application element, said thermally conductive material configured to conduct cold from the absorbent application element and comprising a lip extending circumferentially at least partially around a perimeter of the exposed face; and a layer of insulating material disposed exterior to portions of the thermally conductive material. A device for application of cryogenic matter onto a skin lesion includes an applicator body with two opposing tweezer arms and at least one canister containing cryogenic matter; and first and second disposable tips.

    摘要: A method of interrupting sympathetic stimulation to the cardiovascular system of a patient in need thereof includes navigating a probe of a hand-held cryogenic therapy apparatus to a stellate ganglion or an autonomic tissue area peripheral to the stellate ganglion of the patient, the probe including a needle configured to produce a cooling zone for focused cryogenic therapy, aligning the needle with one or more desired nerves of the stellate ganglion or the autonomic tissue area peripheral to the stellate ganglion, and producing the cooling zone to provide cryogenic therapy to the desired nerves of the stellate ganglion or the autonomic tissue area peripheral to the stellate ganglion at a temperature sufficient to cause axonotmesis of the nerves.
