Abstract: An embodiment of the invention is a cryo-connector, a connector that allows for the delivery and return of a cryogen in an axial configuration. In one embodiment, the connector is a tri-axial configuration allowing for the delivery and return of pressurized cryogen as well as the application of an independent vacuum in the third lumen. Various configurations, however, may accommodate any number of luminary spaces such that cryogen (or other fluids) and/or vacuum spaces may be created in a fashion complementary to the components that the connector will affix to and interconnect with. The connectors can be utilized with any low temperature, cryogenic device and at varying pressures.

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.
Abstract: One embodiment of the invention is a flexible cryogenic probe tip. The flexible probe tip has a linear freeze zone at a distal end of the probe that allows for its placement and precisely controlled movements. The flexible cryogenic probe tip precisely conforms to the target tissue surface to create a linear lesion. In addition, the probe tip is steerable to facilitate proper placement with minimal access points into a patient's body. Various configurations of the flexible probe tip allow it to conform and ablate tissue of many sizes, shapes, and/or dimensions.
