Patent number: 10602740Abstract: An organ perfusion apparatus may include at least two tubes connected to an organ or tissue. A method of perfusing an organ or tissue may include connecting a first end of each of the at least two tubes to an organ or tissue, applying a fluid motive force to a perfusion fluid in the two tubes to force the fluid through the two tubes into the organ or tissue, and perfusing the organ or tissue through the at least two tubes such that the fluid motive force, provided by, e.g., a pump, and backpressure generated by the organ or tissue, establishes a flow balance between the at least two tubes. The flow balance may be altered without altering the fluid motive force that is applied.Type: GrantFiled: July 10, 2012Date of Patent: March 31, 2020Assignee: LIFELINE SCIENTIFIC, INC.Inventors: David Kravitz, Christopher P. Steinman, Jeffrey S. Louis, Matthew Copithorne, Brian L. Otts, Peter Demuylder

Patent number: 9402389Abstract: An apparatus for at least one of storage, treatment, assessment and transport of an organ or tissue includes a coolant container configured to cool the organ or tissue, a perfusion circuit configured to perfuse the organ or tissue, and a sample compartment for holding a biological sample. Preferred apparatus has a first internal compartment under a first cover (lid) of the apparatus that includes the coolant container and the sample compartment. The apparatus can include a second internal compartment under a second cover (lid) of the apparatus, the second internal compartment including at least part of the perfusion circuit and a sample compartment.Type: GrantFiled: July 10, 2012Date of Patent: August 2, 2016Assignee: LIFELINE SCIENTIFIC, INC.Inventors: David Kravitz, Christopher P.

Patent number: 9357767Abstract: A perfusion apparatus includes a coolant container having a basin-receiving recess that is at least partly surrounded by an inner chamber; a basin that is shaped to fit within the basin-receiving recess of the coolant container; and a cradle that is shaped to accept an organ and fit within the basin. The basin-receiving recess of the coolant container, the basin and the cradle each have positioning elements that are oriented such that the cradle is keyed to fit within the basin and the basin is keyed to fit within the coolant container, each in a single predetermined orientation. The plurality of positioning elements on the basin may include a plurality of protrusions on an outer surface of the basin.Type: GrantFiled: July 10, 2012Date of Patent: June 7, 2016Assignee: LIFELINE SCIENTIFIC, INC.Inventors: Christopher P. Steinman, Rick W. Walker, Kirk C. Palmerton, Jeffrey S. Louis, David Pettinato, Matthew Copithorne, Brian L Otts, Peter Demuylder, James Guarrera, Ben O. Arrington

Patent number: 9357766Abstract: A perfusion apparatus including a perfusion circuit that perfuses an organ or tissue has a compartment that supports an organ or tissue during perfusion, an internal cover, and an external cover that closes the apparatus. A wall portion may extend substantially perpendicularly between the internal cover and the external cover to define a document compartment between the internal cover, the external cover and the wall portion. A tamper evident seal will not permit the external cover to open without creating a record of whether the external cover has been opened after the tamper evident seal has been activated.Type: GrantFiled: July 10, 2012Date of Patent: June 7, 2016Assignee: LIFELINE SCIENTIFIC, INC.Inventors: Christopher P.

Patent number: 9162311Abstract: The present invention is directed to a remotely controlled welding machine that uses serializing and modulating circuits to transfer modulated data packets to a welding power source across a weld cable. A transmitter transmits the data packets of desired welding operational parameters to a receiver disposed in the power source across a weld cable also designed to carry welding power from the power source to the wire feeder. The transmitter and other electronics of the wire feeder are constructed to use only a small amount of power which, preferably, is supplied by a DC power supply external to the wire feeder. The DC power supply is designed to provide power to the electronics of the wire feeder when the wire feeder is in a standby mode of operation.Type: GrantFiled: January 22, 2007Date of Patent: October 20, 2015Assignee: ILLINOIS TOOL WORKS INC.Inventor: Brian L. Ott
