Claim:
1. Control system for an arterial catheter operable to selectively impede blood flow in a first artery to augment blood flow in a second artery, comprising: at least one processor; at least one computer memory accessible to the processor and comprising instructions which when executed by the at least one processor configure the at least one processor to execute operations comprising: receiving a first signal representing a physical parameter associated with a patient in whom the catheter is disposed; receiving a second signal representative of time; causing inflation of a first balloon on the catheter to impede blood flow in the first artery; based at least in part on the first signal satisfying a first condition, causing deflation of the first balloon; based at least in part on the second signal indicating elapse of a predetermined time period, causing deflation of the first balloon regardless of whether the first signal satisfies the first condition, wherein the catheter includes a second balloon and the instructions are executable for: inflating the second balloon; based at least in part on the first signal satisfying a condition, causing deflation of the second balloon; and based at least in part on the second signal indicating elapse of a predetermined time period, causing deflation of the second balloon regardless of whether the first signal satisfies the second condition.
