<p>Organs and other tissue structures (O) are isolated which are perfused with a therapeutic agent. Isolation is effected by endovascularly positioning catheters (10, 16) having occlusion balloons (12, 14) within the arteries or other blood vessels which supply blood to the organ. Similarly, blood flow from the organ back to the patient's circulatory system is blocked by endovascularly positioning one or more catheters carrying occlusion members within the veins or other blood vessels leading from the organ. The therapeutic agent may then be perfused through the organ in either an antegrade or retrograde fashion using the endovascularly positioned catheters while maintaining isolation.</p> |
