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.
