Patent number: 12207651Abstract: Disclosed are apparatuses and methods for irradiating a perfusate. The apparatus includes a tank which defines a first chamber. A separator is located inside the first chamber. The separator defines a second chamber. The first chamber and the second chamber are concentric and have substantially annular cross sections, each having at least one diameter and a substantially common longitudinal axis. A perfusate is introduced into the first chamber by an inlet. A UV radiation-emitting device is disposed inside the second chamber for providing irradiation to the perfusate. Irradiated perfusate is removed from the tank by an outlet. Other apparatuses and systems are described and methods for inactivating micro organisms by performing EVP and irradiating the perfusate.Type: GrantFiled: March 29, 2018Date of Patent: January 28, 2025Assignees: University Health Network, Universidade de Sao PauloInventors: Vanderlei Salvador Bagnato, Marcelo Cypel, Shafique Keshavjee, Thomas Kenneth Waddell, Marcos Theophilo Galasso

Publication number: 20220322658Abstract: Methods, systems, and devices preserve donor organs by alternating between static cold storage and ex vivo organ perfusion. Preserving a donor organ includes refrigerating a donor organ to form a once-refrigerated donor organ, perfusing the once-refrigerated donor organ to form a once-perfused donor organ, and refrigerating the once-perfused donor organ to form a preserved, twice-refrigerated donor organ for transplantation.Type: ApplicationFiled: April 6, 2022Publication date: October 13, 2022Applicant: Traferox Technologies Inc.Inventors: Shafique KESHAVJEE, Thomas Kenneth WADDELL, Aadil ALI, Marcelo CYPEL

Patent number: 11045633Abstract: A cannula for connecting a medical device to a biological system is taught. The cannula includes a tissue engagement portion, preferably in the form of an annulus, to which a vacuum is applied through the cannula to attract and hold tissue of the biological system in an initial connection while an affixment device is applied to complete the connection. In addition to a working fluid conduit, comprising a main port, a working fluid passage and a working fluid port, and a port to apply the vacuum, the cannula can include a sensor port to allow sensing pressure or other characteristics of the working fluid at a point closely adjacent to the connection between the cannula and the biological system.Type: GrantFiled: April 10, 2015Date of Patent: June 29, 2021Assignee: UNIVERSITY HEALTH NETWORKInventors: Daniel Gavin Harrison, Geoffrey Samuel Frost, Thomas Kenneth Waddell, Laura Ann Wyvill, Raymond Francis Cracauer, Shafique Keshavjee, Marcelo Cypel, Randy Yang

Publication number: 20190098892Abstract: An organ perfusion device includes an inlet for connection to the organ, and an outlet for connection to the organ. The device also includes a perfusion circuit including: a reservoir configured to hold a perfusion fluid; a waste receptacle, and a plurality of fluid conduits. The fluid conduits define: a delivery fluid path connecting the reservoir with the inlet; a return fluid path, independent of the delivery fluid path, connecting the reservoir with the outlet; and a waste fluid path connecting the reservoir with the waste receptacle. The device also includes a first flow control device configured to selectively prevent or allow fluid flow from the reservoir to the organ via the delivery fluid path; and a second flow control device configured to selectively prevent or allow fluid flow from the reservoir to the waste receptacle via the waste fluid path.Type: ApplicationFiled: October 5, 2018Publication date: April 4, 2019Inventors: Lahav GIL, Siew Hong TAN, Martin Leandro PAR, Philipp STÜCKLIN, Shafique KESHAVJEE, Mingyao LIU, Marcelo CYPEL, David Christopher LYNCH, Thomas Kenneth WADDELL, Geoffrey Samuel FROST, Grzegorz Piotr BURDYSZEK
