    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. Methods of utilizing the cryogenic probe tip include steps of positioning the distal end at a tissue site for at least one ablative procedure, maneuvering the distal end to the tissue site, directing a cryogen from the supply source to the distal end, controlling a flow of cryogen from the supply source to the distal end and back to the supply source, and segmenting control of the distal end mechanically or through the step of controlling the flow of cryogen.

    Abstract translation: 本发明的一个实施例是柔性低温探针尖端。 柔性探针尖端在探头的远端具有允许其放置和精确控制运动的线性冻结区。 柔性低温探针尖端精确地符合目标组织表面以产生线性损伤。 此外，探针尖是可操纵的，以便于以最小的接入点进入患者身体的正确放置。 柔性探针尖端的各种构造允许其适应并消融许多尺寸，形状和/或尺寸的组织。 使用低温探​​针尖端的方法包括以下步骤：将远端定位在组织部位处至少一个烧蚀程序，将远端操纵到组织部位，将冷冻剂从供应源引导到远端，控制流动 冷冻剂从供应源到远端并返回到供应源，并且机械地或通过控制冷冻剂流动的步骤来分段远端的控制。

    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.
