Novel endovascular device for aortic dissection
When the innermost layer of the aorta tears, blood may pass through the intimal tear into the newly created false lumen, obstructing blood flow to organs and weakening the aortic wall. While dissection of the ascending aorta (Type A) requires immediate open surgical repair, dissection of the descending aorta (Type B) requires surgical intervention when organ malperfusion occurs. Malperfusion typically occurs due to the difference in pressure between the true and false lumens, causing the dissection to expand, which may obstruct arteries branching from the aorta. The arterial pressure in the true and false lumens can be equalized by cutting the intimal flap at the distal end of the dissection. The endovascular fenestration procedure is currently performed using two wires via a catheter to slice the intima down the length of the dissection. Our goal is to create a device that will successfully cut the intimal flap of the dissection without the risk of tearing more intimal lining from the aortic wall.
