A device for occlusion of a body passageway and subsequent perfusion of the body passageway with arterial return blood, cardioplegia and other fluid is disclosed. The device of the present invention is an expandable cannula comprising a flexible, expandable tubular elongate body having a first diameter and a second diameter, wherein the expandable cannula is inserted having a first diameter and then expanded to a second diameter to provide perfusion flow to the body passageway through at least one arterial return aperture provided on the distal end of the expandable tubular elongate body in fluid communication with a perfusion lumen provided within the cannula. The device may be further provided with one or more additional lumens for providing additional functions to the vessel lumen and may also include an expandable occluding member fixed at the distal end of the cannula for isolating the surgical area from the rest of the arterial system. A preferred method of use of the present invention is also disclosed wherein having a first diameter is inserted endovascularly into the vessel of a patient and advanced to a point of interest. At the point of interest, the device is expanded to a second diameter and perfusion flow to the vessel lumen is provided. Following the performance of a surgical procedure, perfusion flow is terminated and the device is removed from the vessel. |
