Development of simulator for training of thoracic endovascular aneurysm repair

Thoracic endovascular aneurysm repair(TEVAR) has recently become a surgical option for the high-risk patients with thoracic aortic aneurysm. However, there have been few methods to train the deployment of stent graft in the pulsatile aorta. Thus, we developed a simulator for the training of TEVAR under pulsatile hydrodynamics. Our simulator has been developed so that the roller pump provided in conventional cardio-pulmonary bypass can be used to generate pulsatile flow. Our simulator may provide the excellent training for surgical trainees.
