Abstract

The selective and differential perfusion method includes withdrawing blood through a cannula introduced into a patient's blood vessel. The temperature of such blood is controlled and flowed through an arterial cannula introduced into a selected arterial vessel of the patient for a sufficient time and at a sufficient flow rate to change the temperature of at least a portion of the patient's body. An aortic balloon catheter is introduced into the aorta of the patient to establish fluid communication through the catheter lumen between an external location and an aortic location which is disposed in a preferential flow relationship with a selected branch artery of the aorta leading to a selected region of the patient's body. A balloon mounted on the exterior of said aortic catheter is positioned at a balloon location spaced longitudinally from the aortic location and inflated to resist blood flow while a fluid is communicated through the catheter lumen between the external location and the aortic location. The aortic balloon catheter may further include a second lumen introduced into the aorta to establish a preferential flow relationship with a second branch artery leading to a second region of the patient's body and wherein the balloon location is disposed between the selected branch artery and the second branch artery.
