Arterial device, system and method for removing embolic debris

摘要

An arterial device, system and method are provided for use with a patient undergoing a cardiac procedure. The system is configured for enabling one or more arterial devices to be accommodated in the aorta of the patient in use of the system, and a perfusion lumen arrangement provides therethrough a target perfusion flow into the aorta having a target perfusion flow rate that is significantly greater than a nominal perfusion flow rate, by an excess perfusion flow rate. A suction lumen arrangement provides therethrough a suction flow out of the aorta at a suction flow rate. The target perfusion flow rate and the suction flow rate may be concurrently and selectively controlled to cause embolic debris that may be present in the aorta to be diverted to the suction inlet, while providing the nominal flow rate to the body circulation of the patient.

1. A method for removing embolic debris from an aorta of a patient having a body blood circulation system, said method comprising:
via an arterial flow exchange system, establishing a perfusion flow into the aorta at a perfusion flow rate at a perfusion site; via the arterial flow exchange system, establishing a suction flow out of the aorta at a suction flow rate at a suction site; and selectively controlling said perfusion flow rate and said suction flow rate to establish a recirculation flowfield between the perfusion site and the suction site within the aorta to cause embolic debris that may be present in the aorta to be diverted to the suction flow.
