Patent number: 9629359Abstract: A cannula has a longitudinal base member having a first clamping end and a longitudinal arm member pivotally attached to the longitudinal base member and having a second clamping end, the cannula being in a closed position when the first and second clamping ends are brought together. A first clamp member is located at the first clamping end and has a first passage. A second clamp member is rotatably attached to the arm member at the second clamping end and has a second passage. The first and second passages form a combined passage when the clamp is in the closed position. The cannula may have a first locking member positioned on the arm member and a second locking member positioned on the base member. The first and second locking members interact with each other to lock the cannula in the closed position.Type: GrantFiled: July 18, 2014Date of Patent: April 25, 2017Assignee: LIFELINE SCIENTIFIC, INC.Inventors: Christopher P. Steinman, Jason A. Belton, Kirk C. Palmerton, Karl H. Beitzel, Rick W. Walker, Matthew Copithorne, Brian Otts, James V. Guarrera

Patent number: 9565853Abstract: An apparatus for separating gas bubbles that may be entrained in perfusate flow prevents such bubbles from continuing downstream and entering an organ or tissue. The apparatus may include a chamber having a top wall, a bottom wall and side walls. The chamber may include an inlet configured to allow at least one of gas and liquid to enter the chamber, an air opening configured to allow at least gas to exit the chamber and a first liquid opening configured to allow at least liquid to exit the chamber. The apparatus may function as an accumulator that reduces or eliminates pulsatility of the liquid flow and pressure. The apparatus may include a minimum volume of gas, initially or through the accumulation of gas, such that flow and pressure fluctuations in the liquid are dampened or eliminated. The apparatus may include a sampling port in a wall of the chamber.Type: GrantFiled: July 10, 2012Date of Patent: February 14, 2017Assignee: LIFELINE SCIENTIFIC, INC.Inventors: Christopher P. Steinman, Jeffrey S. Louis, Rick W. Walker, Evan D. Shapiro, Aaron R. Ferber, Rodney H. Monson, John Stark, Ross Lockwood

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: 9259562Abstract: A cannula includes a first clamping surface on a closing portion of the cannula, a second clamping surface on a base of a cannula, a connecting structure that connects the closing portion and the base. The connecting structure may allow the closing portion to be rotated around the second clamping surface. The cannula may include a repeatably removable handle.Type: GrantFiled: July 10, 2012Date of Patent: February 16, 2016Assignee: LIFELINE SCIENTIFIC, INC.Inventors: Christopher P. Steinman, Jason A. Belton, Kirk C. Palmerton, Karl H. Beitzel, Rick W. Walker, David Pettinato, Matthew Copithorne, Brian Otts, James V. Guarrera
