Patent number: 11459534Abstract: An organ container includes flexible films and a tube holder. The films hold an organ in contact with the surface of the organ. The tube holder holds tubes that extend between the organ in the films and an outside of the films. This makes it possible to hold and preserve the organ while allowing a liquid to be perfused through the organ via the tubes. It is also possible to reduce movements of the organ relative to the organ container and to reduce damage to the organ.Type: GrantFiled: October 1, 2018Date of Patent: October 4, 2022Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Shinji Torai, Syuhei Yoshimoto

Patent number: 11447734Abstract: A continuous automated perfusion culture analysis system (CAPCAS) comprises one or more fluidic systems configured to operate large numbers of biodevices in parallel. Each fluidic system comprises an input reservoir plate for receiving media; a biodevice plate comprising an array of biodevices fluidically coupled to the input reservoir plate, configured such that each biodevice has independent media delivery, fluid removal, stirring, and gas control, and each biodevice is capable of continuously receiving the media from the input reservoir plate; and an output plate fluidically coupled to the biodevice plate for real-time analysis and sampling. The operations of the CAPCAS are automated and computer-controlled wirelessly. The CAPCAS can also be used for abiotic and biotic chemical synthesis processes.Type: GrantFiled: January 19, 2022Date of Patent: September 20, 2022Assignee: VANDERBILT UNIVERSITYInventors: Ronald S.

Patent number: 11399536Abstract: A device for support of an organ ex vivo comprises a chamber with a first engagement feature. A support structure includes a second engagement feature. The first and second engagement features may be engaged so that the chamber body is carried by the support structure for rotation. The chamber body comprises first and second chamber components. In a first orientation of the chamber body, the first chamber component provides support for a first surface of the organ, and the second chamber component is removable so that a second surface of the organ is exposed to manipulation from outside the chamber body. In a second orientation of the chamber body, the second chamber component provides support for the second surface of the organ, and the first chamber component is removable so that the first surface of the organ is exposed to manipulation from outside the chamber body.Type: GrantFiled: September 14, 2018Date of Patent: August 2, 2022Assignee: THE CLEVELAND CLINIC FOUNDATIONInventors: Cristiano Quintini, John W.
