An EndoVascular Aneurysm Repair (EVAR) is a procedure used to fix an aneurysm of the aorta. In this procedure, a guide is inserted by the femoral artery. This guide goes through to the height of the aneurysm and then a catheter follows the guide. Next, a stent graft is deployed in order to repair the aortic aneurysm. The objectives of our work is to develop a low-cost robotic system and implement a program that helps the trajectory planning during an endovascular operation. More precisely, this program can predict if the aorta will break or not depending on the guide used. Such a robotic platform could serve as a teaching instrument by creating an environment for young surgeons in which they will be able to practice their skills to perform an EVAR. This paper describes the different components of this platform and provides some experimental results.
