Transplantation and growth of human fetal organs in non-human animal hosts

-17. (canceled)

A method of growing an organ from a human fetus, the method comprising:

• fluidically coupling the organ to an artery of an immunocompromised non-human animal;
• disposing a vascular cuff assembly on the artery, the vascular cuff assembly configured to apply pressure to an exterior surface of the artery;
• adjusting the blood pressure of the arterial blood flow from a first pressure to a second pressure, the second pressure less than the first pressure.

A device for controlling vascular blood flow, the device comprising:

• an inflatable reservoir, the inflatable reservoir having a first end, a second end, and a port configured to allow fluid communication between the inflatable reservoir and a fluid delivery mechanism;
• and
• a retainer disposed on the inflatable reservoir and configured to position the first end of the inflatable reservoir proximate to the second end of the inflatable reservoir, the inflatable reservoir defining a channel configured to receive a blood vessel of a non-human animal.
