Abstract: Embodiments herein relate to a cryoablation probe including a pre-cooler fluid circuit; a working fluid circuit; a vacuum circuit; and a shaft. The shaft includes a supply tube and a return tube surrounding the supply tube. The return tube includes a first polymer layer, wherein the first polymer layer is configured to contain fluid from the working fluid circuit; a reinforcement layer, and a second polymer layer. Other embodiments are also included herein.

Abstract: An energy-delivering treatment system facilitating determination of various characteristics of a lesion and/or tissue at a treatment site, such as the size and/or location of the lesion; stiffness and/or elasticity of the tissue; impedance or resistance of the tissue (which may impact the form of energy such as electroporation and/or irreversible electroporation applied to the tissue); and/or the effects of a treatment applied to the lesion. Information gathered regarding the treatment site may be used to aid in predicting and measuring lesions, and/or in determining an appropriate treatment plan on a patient-by-patient basis. Markers may be used to facilitate locating of the treatment site after the energy-delivering assembly has been withdrawn from the treatment site.

Abstract: In an embodiment, a method for detecting leaks in a shaft of a cryoablation system includes placing a vacuum pump in fluid communication with a return tube and a supply tube; pulling a vacuum within the supply tube and the return tube; after pulling the vacuum for a predetermined amount of time, measuring a vacuum pressure within the supply tube and the return tube; and analysis of the vacuum pressure to assist with identifying leaks in the system.
