Abstract
A control system for an arterial catheter operable to selectively impede blood flow includes a processor and a storage medium accessible to the processor that bears instructions which when executed by the processor cause the processor to execute logic including 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, and 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, the instructions include causing deflation of the first balloon. Based at least in part on the second signal indicating elapse of a predetermined time period, the instructions include causing deflation of the first balloon regardless of whether the first signal satisfies the first condition.
