Aortic shunt with spinal perfusion and cooling device

Year	Description
1999	Invention patented by Denise R. Barbut on November 15th, 1999. Abstract: An intravascular device comprising an intra-aortic and extra-aortic component for perfusing the spinal arteries during thoracoabdominal surgeries. The intra-aortic component comprises a catheter having a shunt releasably mounted on a distal end of the catheter. An expandable occluder is disposed about the shunt for occluding the aortic lumen. The extra-aortic component comprises a tubular member having a lumen communicating with a first end and a second end. The first end is adapted for attachment to the shunt. The second end of the second tubular member is attached to a plurality of tubular branches. A cooler may be attached to the second tubular member for providing hypothermic perfusion. When the intra-aortic component is attached to the extra-aortic component, blood flows from the proximal aorta to the spinal arteries through the lumens of the tubular branches. Methods of using the device for spinal perfusion during thoracoabdominal surgeries herein are also disclosed.
