When the reactant inlet is in the open state, the reactant inlet provides a flow path for enabling the second endothermic reactant to come into contact with the first endothermic reactant in the chamber for initiating the endothermic reaction and cooling the target fluid in the inner conduit.Type: GrantFiled: February 24, 2010Date of Patent: December 17, 2013Assignee: North Carolina State UniversityInventors: Andrew J. DiMeo, Nathan M. Cox, Steven P. Grove, Samuel Lee, Luke D. Oltmans, Kathryn H. Sauer

Patent number: 8585645Abstract: Methods are describe for treating intraluminal locations such as in a patient's lung. The device is a catheter which has an elongated shaft with an inner lumen, preferably defined by an inner tubular member, formed of heat resistant polymeric materials such as polyimide and high temperature vapor is directed through the inner lumen into the intraluminal location to treat tissue at and/or distal to the location. The outer surface of the catheter is also formed of heat resistant material. An enlarged or enlargeable member, such as a balloon, is provided on a distal portion of the catheter shaft to prevent proximal flow of the high temperature vapor upon discharge from the catheter.Type: GrantFiled: November 13, 2006Date of Patent: November 19, 2013Assignee: Uptake Medical Corp.Inventors: Robert Barry, Dean Corcoran, Brian Cran, Michael Hoey, Sheldon Lee, Peter Lyons

Publication number: 20130298903Abstract: A portable, disposable, thermal drug dispensing apparatus and method of thermally controlling the delivery of medication therewith is provided. The apparatus provides a predetermined thermal energy over a predetermined amount of time to allow effective drug delivery regardless of the external environment. The apparatus produces exothermic or endothermic thermal energy, in a balanced and controlled environment via a chemical reaction between reactants contained as an integral part within the apparatus. The reactants are provided and automatically combined in a selective, predetermined manner within the apparatus to provide the desired thermal cycle needed to produce the desired, thermal environment for effective drug treatment.Type: ApplicationFiled: May 13, 2013Publication date: November 14, 2013Inventor: David W. Wright

Patent number: 8579880Abstract: Methods and devices for treating patients using high partial pressures of dissolved gas in a liquid. Greater than hyperbaric partial pressures of gas may be dissolved and maintained in the liquid when mixing occurs at ambient pressure. Additional increases in dissolved gas partial pressure may be achieved when the temperature of the liquid is further decreased. The method further includes administering the liquid intravenously via a conventional catheter. Gas exchange occurs due to diffusion upon mixing of the liquid and blood within the vasculature of the patient.Type: GrantFiled: March 1, 2012Date of Patent: November 12, 2013Assignee: Outcome Solutions, LLCInventors: Daniel J. Grady, Johnny Harold Riggs
