Publication number: 20160042084Abstract: Methods of monitoring, maintaining, and/or restoring viability of at least one organ in a perfusion apparatus are disclosed. The methods include monitoring data comprising information relating to events occurring while at least one organ is present in a perfusion apparatus to form a data record. And they further include connecting the perfusion apparatus to a network through wiring or wirelessly, and continuously uploading the data record to a database at a location away from the perfusion apparatus in such a manner that a database computer that obtains the data record from the database can at least one of manage, track, monitor, and diagnose the at least one organ in the perfusion apparatus in real-time based upon the information in the data record.Type: ApplicationFiled: October 21, 2015Publication date: February 11, 2016Inventors: Donald R. OWEN, David C. KRAVITZ, John BRASSIL, Kelvin G.M. BROCKBANK, Andrew BURROUGHS, Douglas SCHEIN, Stanley HARRIS, Dennis J. STEIBEL, Richard FRASER, Christopher G. CURTIS

Patent number: 8962303Abstract: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. In perfusion, organ perfusion pressure is preferably controlled in response to a sensor disposed in an end of tubing placed in the organ, by a pneumatically pressurized medical fluid reservoir, providing perfusion pressure fine tuning, overpressurization prevention and emergency flow cut-off. In the hypothermic mode, the organ is perfused with a medical fluid, preferably a simple crystalloid solution containing antioxidants, intermittently or in slow continuous flow. The medical fluid may be fed into the organ from an intermediary tank having a low pressure head to avoid organ overpressurization. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate.Type: GrantFiled: August 10, 2011Date of Patent: February 24, 2015Assignee: Lifeline Scientific, Inc.Inventors: Donald R. Owen, David C. Kravitz, John Brassil, Kelvin G. M. Brockbank, Andrew Burroughs, Dickon Isaacs, Douglas Schein

Patent number: 8609400Abstract: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The method includes perfusing the organ at hypothermic and/or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and/or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate. The perfusion process can be automatically controlled using a control program.Type: GrantFiled: May 12, 2010Date of Patent: December 17, 2013Assignee: Lifeline Scientific, Inc.Inventors: Donald R. Owen, David C. Kravitz, John Brassil, Kelvin G. M. Brockbank, Andrew Burroughs, Dickon Isaacs, Douglas Schein

Patent number: 8431385Abstract: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. The method includes perfusing the organ at hypothermic and/or normothermic temperatures, preferably after hypothermic organ flushing for organ transport and/or storage. The method can be practiced with prior or subsequent static or perfusion hypothermic exposure of the organ. Organ viability is restored by restoring high energy nucleotide (e.g., ATP) levels by perfusing the organ with a medical fluid, such as an oxygenated cross-linked hemoglobin-based bicarbonate medical fluid, at normothermic temperatures.Type: GrantFiled: January 21, 2011Date of Patent: April 30, 2013Assignee: Lifeline Scientific, Inc.Inventors: Donald R.

Patent number: 8361091Abstract: A cannula connects an organ with a perfusion system that monitors, treats, sustains and/or restores the viability of the organ and/or that transports and/or stores the organ. At least part of a cannula may be made of a soft elastomer to help avoid damage to the organ. In embodiments, the cannula includes a top portion, a bottom portion, a sealing ring and two compression straps. In embodiments, the cannula includes a top portion and a flexible bottom portion that may be attached to the top portion. In embodiments, part of the cannula is inserted directly into an artery and a suture is used to tie the artery in place. Also, the cannula may include an attachment feature that can be used to connect the cannula to an organ platform or chair. Various features of the cannula may allow a visual check for and venting of air bubbles in the cannula.Type: GrantFiled: August 25, 2003Date of Patent: January 29, 2013Assignee: Organ Recovery Systems, Inc.Inventors: Douglas A.
