The present disclosure relates to devices and methods for increasing the probability of a successful organ donation by decreasing organs' warm ischemia time. Furthermore, the present disclosure relates to increasing the pool of eligible donors, including donors who had prior chest surgeries or prior abdominal surgeries. The present disclosure provides a catheter extending through a cannula, wherein the cannula delivers cold perfusion fluid and the catheter blocks the aorta, forcing the cold perfusion fluid to pass to organs in the donor's abdomen. The present disclosure further provides for advancing the catheter from a retracted position to an extended position, and creating a watertight seal at the cannula to prevent backflow of cold perfusion fluid.
