"The Zenith Dissection Endovascular System is a device designed for treatment of aortic type B dissection as described by the Provisional ExTension to Induce COmplete ATtachment (PETTICOAT) technique.

Careful catheter manipulation after deployment and accurate review of postoperative imaging are warranted."
