Publication number: 20150257810Abstract: 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.Type: ApplicationFiled: May 18, 2015Publication date: September 17, 2015Inventors: John M.

Patent number: 8747397Abstract: 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.Type: GrantFiled: November 21, 2012Date of Patent: June 10, 2014Assignee: CPSI Holdings LLCInventors: John M.

Patent number: 8551081Abstract: A cryosurgical system and method for supplying cryogen to a probe. The system including a container filled with cryogen and having bellows of a pump submerged within said cryogen. Conduits fluidly interconnect the bellows and a probe that is outside the container to permit the cryogen to be forced from the bellows to the probe upon activation of pump. A pressure relief valve is fluidly coupled to the conduits and positioned between the bellows and the probe. After initially forcing cryogen to the probe at a pressure that establishes a colligative-based sub-cooling of the liquid cryogen, the pressure relief valve is activated to lower the pressure of the cryogen to a running pressure.Type: GrantFiled: October 3, 2010Date of Patent: October 8, 2013Assignee: Endocare, Inc.Inventors: John G. Baust, Roy Cheeks

Patent number: 8439905Abstract: The device of the invention takes the form of a catheter/probe and is a closed loop system in which cryogen is delivered along the length of the catheter/probe to the tip where freezing occurs, and then recirculated. The device is a tube within a tube and comprises a number of parts including supply and return (internal) tubes, outer sheath (external tube) seaJed to the inner tubes at one or both ends with a gas filled lumen between the internal and external tubes. The lumen of the external tube is filled with a saturated gas which solidifies upon cooling, thereby creating a vacuum along the catheter length and providing for insulation between the inner and outer tubes, and preventing freezing along the probe shaft length. The outside surface of the internal tubes is modified to potentiate gas nucleation on the outer surfaces of the internal tubes when cooled.Type: GrantFiled: September 18, 2009Date of Patent: May 14, 2013Assignee: Endocare, Inc.Inventors: John M.

Publication number: 20120028933Abstract: 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.Type: ApplicationFiled: July 28, 2011Publication date: February 2, 2012Inventors: John M.
