Abstract:
A method for placing a shunt, comprising the steps of:providing a 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; inserting the catheter into the aorta, wherein the valve is in a closed state; expanding the occluder at a location in the aorta to stop blood flow through the aorta at the location of the occluder; releasing the shunt by detaching the shunt from the catheter; and operating the valve between a closed state and an open state to allow blood flow from the aorta upstream of the shunt and through the valve.
