<p>A blood flow control system for controlling the amount of blood flowing through an artery to an organ consists of an inflatable occluder (10) that is placed around the artery and an implanted device (15) for actuation of the cuff. The implanted device is in fluid communication (13, 14) with the occluder (10). The amount of blood flow through the artery is controlled by the transcutaneous operation of the implanted device (15). The blood flow control system is particularly suitable for controlling the flow of blood to secondary tumors of the liver by intermittent compression of the hepatic artery as an adjustment to the direct infusion of chemotherapeutic agents. The system can also be used to occlude the splenic artery to treat hypersplenism.</p> |
