The aim of this study was to manufacture life-size, flexible, tubular replicas of human abdominal aortic aneurysms and the associated vasculature, suitable for use in a training simulator for endovascular procedures. Selective laser sintering was used to create a geometrically correct master model for each of ten anatomical variations. The masters were used to generate flexible latex replicas. The use of the replicas in the training simulator was demonstrated. In total ten silicone rubber models were produced. When connected into the training simulator and perfused at arterial pressure it was possible to deploy an endovascular stent under fluoroscopic control and to perform angiography. The study has shown that conventional rapid prototyping technology can be used to manufacture flexible, radiolucent replicas which provide a realistic training environment for endovascular procedures.
本研究的目的是制造真人大小、灵活的人体腹主动脉瘤及相关脉管系统的管状复制品，适用于血管内手术训练模拟器。采用选择性激光烧结技术为十种解剖变异中的每一种创建几何形状正确的母模。这些母模用于生成柔性乳胶复制品。展示了这些复制品在训练模拟器中的使用。总共制作了十个硅橡胶模型。当连接到训练模拟器并在动脉压力下灌注时，可以在荧光镜控制下部署血管内支架并进行血管造影。该研究表明，传统的快速成型技术可用于制造灵活的、可透射线的复制品，为血管内手术提供逼真的训练环境。
