We are developing a software to simulate how a medical device is used in the endovascular repair of abdominal aortic aneurysms (AAA) which are characterized by a ballooning of the aorta below the renal arteries. The objective is to predict the deployment of vascular prostheses called stent-grafts (SG) introduced with catheters, as a less invasive alternative than the classic "open" surgery in which the patient's abdomen is opened and the prosthesis stitched directly in the aorta. In any case, such vascular prostheses exclude the aneurismal sac from blood pressure, thus limiting the rupture risk.

我们正在开发一种软​​件，以模拟医疗设备如何用于腹主动脉瘤（AAA）的血管内修复，其特征在于肾动脉下方的主动脉的气球。目的是预测带有导管引入的称为支架移植物（SG）的血管假体的部署，这是一种比经典的“开放”手术的侵入性替代方案，在该手术中，患者的腹部张开，并直接在主动脉中缝合了假体。无论如何，这种血管假体将血压排除在血压之外，从而限制了破裂风险。
