 The Zenith TX2 TAA Endovascular Graft is a reinforced fabric tube that is sized to the length of the aorta that needs to be covered to seal off the aneurysm ulcer. The graft is made of a polyester material like that used in open surgical repair. Standard surgical suture is used to sew the graft material to a frame of self-expanding stainless steel stents, which provide support. The materials used in the Zenith TX2 system have a long history of use in medical implants.
