The Cratos™ Thoracic Branch Stent Graft System is the second-generation uni-body branched stent graft system equipped with an updated delivery system. It is designed for the treatment of descending aortic lesions, such as aneurysm, Stanford type B aorta dissection, IMH, and isolated PAU in patients with appropriate landing zones. Cratos™ inherits the robust design of Castor™, and their stent grafts share nearly the same structure. The integrated side branch stent can minimize the risk of type III endoleak and migration. Regarding the delivery system, Cratos™ has been redesigned to assist physicians in achieving a faster, safer, and easier operation. The smallest outer sheath profile of the delivery system has decreased to 22F. The major added features of the new delivery system include the new active bird-peak control design and the misuse-proof mechanism of deployment trigger wires. With the assistance of active bird-peak control, the proximal sealing zone stent can be adjusted and conform better to the curved aorta arch vessel wall. The misuse-proof mechanism of deployment trigger wires simplifies the operation and ensures that all deployment steps follow sequentially.
