Hercules™ Bifurcated Stent-Graft System is indicated for the endovascular treatment of infrarenal abdominal aortic aneurysm with proximal neck length >15 mm. The stent graft system adopts a two-pieces design, is assembled in the patient, and the operation and release are simple and easy. The heightened design of the branch segment makes the stent more adaptable to the twisted iliac artery.
