    Abstract: A cryogenic medical device for delivery of subcooled liquid cryogen to various configurations of cryoprobes is designed for the treatment of damaged, diseased, cancerous or other unwanted tissues. The device is a closed or semi-closed system in which the liquid cryogen is contained in both the supply and return stages. The device is capable of generating cryogen to a supercritical state and may be utilized in any rapid cooling systems. As designed, the device comprises a number of parts including a vacuum insulated outer dewar, submersible cryogen pump, baffled linear heat exchanger, multiple pressurization cartridges, a return chamber, and a series of valves to control the flow of the liquid cryogen interconnected with cryotreatment devices including cryoprobes and catheters. The cryogenic medical device promotes subcooling to the tips of various external cryogenic instrument configurations.

    Abstract: A cryogenic medical device is disclosed for use in minimally invasive surgical procedures. Various configurations of cryoprobes are designed in combination with a clamp to form a cryoclamp for the treatment of damaged, diseased, cancerous or other unwanted tissues. The device is an integrated cryoablation probe with a hinged clamp that allows for single entry into the chest cavity through a thorascopic port, by surgical or other means. The integrated cryoablation probe allows for the clamping of tissue as well as freezing with a single device. The clamp acts as an outer sheath so that when closed, directional freezing of the cryoprobe is achieved on the opposing probe surface away from the clamp or on an internal surface that is between the clamp. The cryoclamp may be a removable attachment or integrated into the unitary device.
