A method for perfusing a body organ or tissue with blood or a blood substitute, comprising the steps of connecting the organ or tissue to pump means with a conduit, and pulsating the blood or blood substitute within the tissue or organ by operating the pump means at a frequency substantially greater than the normal pulsation frequency of the heart to produce an amplified dynamic pressure wave form in the blood or blood substitute within the microcirculatory vessels to increase the penetration of the blood or blood substitute into the body tissue or organ.
