Patent number: 8741555Abstract: 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. During the period in which the organ is preserved and/or maintained, the organ may be additionally be perfused to obtain data regarding the fluid and/or organ. The data may then be used to ultimately provide information regarding the perfusion efficacy and allow for altering of the perfusion parameters.Type: GrantFiled: May 14, 2004Date of Patent: June 3, 2014Assignee: Organ Recovery Systems, Inc.Inventors: John Brassil, Simona Baicu

Patent number: 7897327Abstract: A method for controlling a pump for delivery of liquid to an organ over a series of fixed-length time intervals f, each interval f comprising a time t1 and a time t2 wherein t1+t2 equals the length of interval f. The method comprises allowing output pressure of the pump to decrease over time t1, increasing output pressure of the pump over time t2, comparing achieved pump output pressure to a predetermined pressure at about the end of interval f, and at least one of (i) adjusting t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f, and (ii) adjusting a rate of change of the output pressure during at least one of t1 and t2 if necessary so the predetermined pressure is approximated by the output pressure at the end of the next interval f.Type: GrantFiled: June 2, 2003Date of Patent: March 1, 2011Assignee: Organ Recovery Systems, Inc.Inventors: Roger Millis, John Foley, Doug Schein, John Brassil

Patent number: 7157222Abstract: A method for vitrification of a tissue or organ includes immersing the tissue or organ in increasing concentrations of cryoprotectant solution at a temperature greater than ?15° C. to a cryoprotectant concentration sufficient for vitrification; cooling the tissue or organ at an average rate of from 2.5–100° C. per minute to a temperature between ?80° C. and the glass transition temperature; and further cooling the tissue or organ at an average rate less than 30° C. per minute to a temperature below the glass transition temperature to vitrify the tissue or organ. After the vitrified tissue or organ has been stored, the tissue or organ may be removed from vitrification by warming the tissue or organ at an average rate of from 20–40° C. per minute to a temperature between ?80° C. and the glass transition temperature; further warming the tissue or organ at a rate greater than 80° C. per minute to a temperature above ?75° C.; and reducing the concentration of the cryoprotectant.Type: GrantFiled: August 25, 2003Date of Patent: January 2, 2007Assignee: Organ Recovery Systems, Inc.Inventors: Bijan S.

Patent number: 6977140Abstract: An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. 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. 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.Type: GrantFiled: March 29, 2000Date of Patent: December 20, 2005Assignee: Organ Recovery Systems, Inc.Inventors: Donald R.
