ABSTRACT:
Described is a medical device and method for allowing fenestration of the aortic wall while maintaining distal perfusion and preventing external bleeding. The device isolates a segment of the aortic wall from the flowing column of blood using a balloon mounted on a metal alloy strut assembly. The strut assembly expands radially from a collapsed, low-profile configuration when uncovered by a constraining outer sheath. Aortic blood flow is allowed through the flow passage thus contained by the strut assembly within the center of the balloon. The balloon is inflated to contact the aortic wall. The balloon contains a pocket shaped to allow aortic fenestration. The balloon contains radiopaque markers to facilitate orientation and positioning of the pocket within the aorta. Other embodiments using spaced balloons are also disclosed.
