Abstract: An apparatus and methods for treating lesions on skin are presented. The apparatus collects information about a lesion and can automatically determine a course of treatment for the lesion. The device can include a controller that positions the nozzle proximate to a surface region of the lesion and automatically dispenses a pulse of the cryogenic fluid from the nozzle. The controller then positions the nozzle proximate to another surface region of the lesion and automatically dispenses a pulse of the cryogenic fluid from the nozzle.

Abstract: The invention is a device that generates a cool fluid stream that has properties adequate to remove superficial layers of tissue. The stream is generated to render the target tissue much more brittle in its mechanical behavior than it would otherwise be; principally by temperature and pressure rise and decay rates. The primary intended use is for dermatologic skin resurfacing, though it may be used to remove superficial layers of tissue anywhere in the body.

Abstract: A blood vessel occlusion system and method includes a handheld probe including a power source, the probe being adapted to transmit energy from the power source through a body surface and into a target blood vessel, for example a varicose vein. Further included is a manual or automatic switch mechanism adapted to enable and disable the power source in response to a predetermined level of compression applied, by means of the probe against the target blood vessel.

Further included is a manual or automatic switch mechanism adapted to enable and disable the power source in response to a predetermined level of compression applied, by means of the probe against the target blood vessel. When the blood vessel is compressed sufficiently to collapse and substantially slow or substantially prevent a flow of blood therethrough, the power source is activated and the vessel is cauterized, leaving the blood vessel in a condition that is resistant to recanalization.
