Abstract

The design and development of a simulator for endovascular repair of abdominal aortic aneurysm (AAA) is described. The simulator consists of an interchangeable model of a human AAA based on computed tomography data and is produced by means of computer-aided design and manufacture (CAD/CAM) techniques. The model has renal, iliac, and femoral arteries, and is perfused with a temperature controlled blood–analog fluid under simulated physiological flow conditions. “Fluoroscopic imaging” is simulated by a computerized imaging system that uses visible light. A movable video camera relays images in the antero–posterior and lateral planes of the AAA to a monitor. The imaging system allows “arteriography” and “road-mapping” to be performed so as to facilitate accurate deployment of endovascular stent-grafts. The system has been used for teaching and demonstrating endovascular techniques to clinicians, as well as the evaluation of new stent-graft devices. Its successful incorporation into endovascular workshops has demonstrated its role in the training of clinicians in endovascular repair of AAA. © 1998 Biomedical Engineering Society.
