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.

Claims18

Dependent claims

A method for perfusing the spinal vasculature of a patient, comprising the steps of:

inserting a catheter into the aorta, the catheter having a proximal end, a distal end, and a shunt releasably mounted on the distal end, the shunt comprising a tubular member having a first end, a second end, and a lumen therebetween, an expandable occluder disposed about the tubular member, and a valve to control fluid flow through the lumen;
expanding the occluder;
releasing the shunt by detaching the shunt from the catheter;
making an incision in the aorta downstream of the occluder, attaching a first end of a second tubular member to the tubular member of the shunt, the second tubular member having a second end, a lumen, and a plurality of tubular branches attached to the second end of the tubular member, each tubular branch having a lumen communicating with the lumen of the tubular member;
inserting the distal end of each tubular branch into a spinal artery;
sealing the distal end of each tubular branch;
and
opening the valve to flow blood through each tubular branch into the spinal arteries.
