Patent number: 11963707Abstract: A cryogenic medical device for delivery of subcooled liquid cryogen to various configurations of cryoprobes is designed for the treatment of damaged, diseased, cancerous or other unwanted tissues. The device is a closed or semi-closed system in which the liquid cryogen is contained in both the supply and return stages. The device is capable of generating cryogen to a supercritical state and may be utilized in any rapid cooling systems. As designed, the device comprises a number of parts including a vacuum insulated outer dewar, submersible cryogen pump, baffled linear heat exchanger, multiple pressurization cartridges, a return chamber, and a series of valves to control the flow of the liquid cryogen. The cryogenic medical device promotes the subcooling to any external cryogenic instrument.Type: GrantFiled: November 18, 2019Date of Patent: April 23, 2024Assignee: VARIAN MEDICAL SYSTEMS, INC.Inventors: John M. Baust, John G. Baust, Roy Cheeks, Anthony Robilotto, Kristi Snyder

Publication number: 20210113256Abstract: A cryogenic medical device is disclosed for use in minimally invasive surgical procedures. Various configurations of cryoprobes are designed in combination with a clamp to form a cryoclamp for the treatment of damaged, diseased, cancerous or other unwanted tissues. The device is an integrated cryoablation probe with a hinged clamp that allows for single entry into the chest cavity through a thorascopic port, by surgical or other means. The integrated cryoablation probe allows for the clamping of tissue as well as freezing with a single device. The clamp acts as an outer sheath so that when closed, directional freezing of the cryoprobe is achieved on the opposing probe surface away from the clamp or on an internal surface that is between the clamp. The cryoclamp may be a removable attachment or integrated into the unitary device.Type: ApplicationFiled: December 11, 2020Publication date: April 22, 2021Inventors: John M. Baust, John G. Baust, Roy E. Cheeks, Anthony Robilotto

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: 20110060323Abstract: 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: ApplicationFiled: October 28, 2009Publication date: March 10, 2011Inventors: John M.
