Abstract
An aortic stent-graft model is provided. A hollow Y-frame is cast from polyurethane to form a core. After silicone aortic wall thickness and aneurysmal segments are applied to the contour of the core, the polyurethane core is removed to leave a hollow aortic model of silicone. Marking indicia are applied to the aortic model to effect selected dimensional measurements. The model can be utilized to calibrate the equipment of testing modalities such as contrast aortography (CA), spiral computed tomography (CT), magnetic resonance imaging (MRI), and intravascular ultrasonography (IVUS). Dimensional measurements from the marking indicia are compared to corresponding images of the model to detect any variation needed for calibration. An aortic stent-graft model can also be utilized to simulate introduction of a guidewire and catheter for deployment of a stent for repair of an abdominal aortic aneurysm (AAA).
