    摘要: The present disclosure relates to a thermal ablation probe device that integrates deployable sensors with a freezing probe or heating probe for use in ablating tissues. The ablation probe includes a longitudinal body including a thermal ablation energy source which may be, e.g., a cryosource or a heat source. The longitudinal body has a proximal end and a distal end terminating at a probe tip; and at least one deployable assembly disposed within the longitudinal body. The deployable assembly includes a flexible and substantially rigid deployment member, and at least one sensor affixed to a distal end of the deployment member. The ablation probe further includes a control mechanism for controlling deployment and retraction of the deployable assembly.

    摘要: A novel class of agents has been identified to serve as cell-guard agents and/or target-specific supplements to increase cell quality and yield, as well as select for target cell populations. Laboratory experiments have demonstrated the use of cell-guard agents and/or target-specific supplements in the bioprocessing of cells as well as in selecting out a desired cell population. Several potential additive agents (both natural and synthetic) have been identified during these studies, including Vitamin D3, NAC, resveratrol, salubrinal, AKT, and tunicamycin (among others) that hold promise for application in cell models. In one embodiment, hypothermic stress regimes are utilized. In another embodiment, normothermic conditions are utilized while other stressors are tested in the processing. The methods of maintaining mass cell cultures and/or selecting out particular cell populations for further research and clinical use represents an important step in therapeutic discovery. The cell-guard agents are process-matched and cell-matched to protect and/or select particular cells during laboratory and clinical manipulation. The components modulate cell stress and survival pathways.

    摘要: The resorbable cryoprobe device and process is a novel approach for treating localized disease allowing for the precise combined application of freezing temperatures and cytotoxic or cryosensitizing agents within a self-contained matrix/package for optimized tissue destruction. The cryopellet is comprised of a list of components including a source of cryogen to produce the sub-zero temperatures, a porous matrix to contain the cytotoxic agent, cytotoxic agent, and a delivery packet. Data presented herein demonstrates the efficacy of this approach in destroying cancerous tissue. For example, the application of freezing temperatures to −10° C. results in approximately 15% cell death, while exposure to cytotoxic agents such as TRAIL produces minimal cell death. The utilization of the cryopellet approach results in a synergistic effect yielding complete cell death at the same temperature. The innovation behind the resorbable probe application includes the strategic combination of agents to activate intrinsic or extrinsic cell death responses (including apoptosis and necrosis), unique packaging of the cryogen and cytotoxic agent, and a unique delivery system. The resorbable cryoprobe technology will assist directly in the treatment of cancer, as well as will likely lead to broader application for disease treatment.

    摘要: A cryoablation device is provided herein which, in an embodiment, includes a catheter shaft; a cryogen return line disposed within the catheter shaft; and a cryogen supply line disposed within the cryogen return line, such that the cryogen supply line, the cryogen return line, and the catheter shaft are all substantially coaxial. A needle tip probe is disposed at a distal end of the cryogen return line. The cryogen supply line extends in a distal direction beyond a distal end of the cryogen return line and into the needle tip probe, and the catheter shaft is axially movable relative to the needle tip probe and the cryogen return line, and the catheter shaft is configured such that the catheter shaft is distally extended over the needle tip probe in an extended position.

    摘要: A cryogenic system as well as a method of generating a pressurized, sub-cooled mixed-phase cryogen and a method of delivering such a cryogen to a cryoprobe are disclosed. In an embodiment, the cryogenic system includes a reservoir containing a liquid cryogen and a sub-cooling coil immersed in the liquid cryogen. The cryogen is supplied to the sub-cooling coil and is cooled under pressure to produce a pressurized mixed phase cryogen within the sub-cooling coil. This pressurized mixed phase cryogen is provided via supply line to a cryo-device for use.
