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

Publication number: 20200030018Abstract: An ablation instrument having a longitudinal body with a plurality of sidewalls that form a flexible sleeve, where the plurality of sidewalls that form the flexible sleeve are slotless. The longitudinal body has a proximal end, a distal end, and a central axis. A luminary space is formed within the plurality of sidewalls and at least one internal component is inserted through the proximal end of the longitudinal body and extends through the luminary space to the distal end. The internal component is interconnected with a deflection mechanism for controlling the distal end of the longitudinal body such that the distal end is capable of multi-planar movement.Type: ApplicationFiled: October 4, 2019Publication date: January 30, 2020Inventors: John M.

Patent number: 10336984Abstract: 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. Several additive agents (both natural and synthetic) have been identified, 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: GrantFiled: August 6, 2015Date of Patent: July 2, 2019Assignee: CPSI Holdings LLCInventors: John M.
