Fontus? Branched Stent Graft System in Surgical Operation, a new generation of surgical stent graft product of Endovastec? after CRONUS?, is indicated for the surgical treatment of Stanford type A aortic dissection and Stanford type B aortic dissection that cannot be treated with conventional interventions. It adopts the new design and optimized manufacturing process, which meet more clinical needs of aortic surgery: Unibody design of the main stent and branch can avoid the deep dissociation of the left subclavian artery during surgery, move up the mainbody anastomosis, lower the surgery difficulty, and shorten the surgery time; the proximal coated artificial blood vessel can reach up to 100 mm long, convenient for surgeons to adopt different surgical strategies; the main stent can be pre-bent, the branch angle can be adjusted, and the overall stent is constrained by soft sheath to ensure the smooth implantation, and achieve the precise release from near to far; the stent material and graft are optimized and upgraded to gain the better anti-leakage performance and vascular compliance.

● Unibody design of main stent and branch, mainbody anastomosis moved up, further simplifying the operation

● The proximal coated artificial blood vessel can reach up to 100 mm long, meeting the needs of different surgical strategies

● Materials and structure design of the product are upgraded to obtain the better performance and smoother operation
