Publication number: 20220016562Abstract: A frusto-conical filter includes at least one layer of a filtering material, wherein one or more layers of the at least one layer of a filtering material comprises a plurality of pleats. Each of the pleats has a center axis which essentially maintains a constant distance from the center axis of its adjoining pleats. The media filter has a first end and a second end, the second end being spaced apart from the first end, and one of the first and second ends is larger than the other of the first and second ends. A method of making this media involves cutting out a frusto-conical section from a generically shaped media and aligning it in such a way as to maintain the constant distance of the pleats from the adjacent pleats.Type: ApplicationFiled: December 2, 2019Publication date: January 20, 2022Applicant: XFINIO, LLCInventors: MAJID ZIA, MICHAEL SPEARMAN, ALLAN ALDEN, MARTIN GENE MILLER

Patent number: 8945040Abstract: An apparatus and method for on-the-go humidifying an insufflation gas through water vapor transfer from a liquid to the insufflation gas through a barrier separating the gas from the liquid to enable the gas in a normally trauma inducing state to be brought to a conditioned state. If the gas is at an improper insufflation temperature the temperature of the gas can be brought to the proper insufflation temperature at the same time the gas is humidified through heat transfer through the barrier.Type: GrantFiled: July 31, 2012Date of Patent: February 3, 2015Assignee: Lexion Medical LLCInventors: Michael Spearman, John H. Burban, Douglas E. Ott, Majid Zia

Patent number: 8425663Abstract: A process for the extraction of an unwanted material from a gas comprising the steps of introducing an extraction liquid into a fluid having an unwanted liquid therein to form a physical aerosol comprising a plurality of extraction liquid droplets and the fluid, allowing the plurality of extraction liquid droplets to interact with the unwanted liquid in the gas to cause the extraction liquid droplets to be “wetted out” and captured on a porous medium, where the liquid is further contacted by the gas and simultaneously formed into a plurality of coalesceable droplets, coalescing the coalesceable droplets into larger droplets containing the unwanted liquid, and separating the larger droplets containing the unwanted liquid from the fluid.Type: GrantFiled: October 30, 2007Date of Patent: April 23, 2013Inventors: Matt Thundyil, Michael Spearman, Martin Miller, Doug Mittlesteadt, Heath Burns, Carl Hahn
