Aortic shunt for selective cerebral perfusion in stroke and cardiac arrest

An aortic shunt, comprising:

• a first tubular member expandable between a first diameter suitable for passage through the lumen of the aorta and a second diameter that frictionally engages the lumen of the aorta, the first tubular member having a length that spans from the ascending aorta upstream of the brachiocephalic trunk to the descending aorta downstream of the left subclavian artery, the first tubular member having a proximal opening, a distal opening, and a lumen therebetween;
• and
• a second tubular member having a proximal end, a distal end, and a lumen therebetween, the distal end of the second tubular member communicating with a port mounted on an intermediate portion of the first tubular member, the port adapted to communicate with the carotid arteries when in use, the proximal end of the second tubular member extending to a position outside of the patient's body and adapted to receive infusion of oxygenated blood,
• wherein, during use, oxygenated blood flows through the second tubular member into the carotid arteries while blood from the ascending aorta flows through the first tubular member into the descending aorta.
