摘要：
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.
