3D printed mechanically representative aortic model made of gelatin fiber reinforced silicone composite

Additive manufacturing (AM) is a useful technology to produce artificial aortic models for the training of transcatheter valve replacement (TAVR) surgery. With AM, can be tailored towards individualized anatomy patients. Most these reported so far are manufactured using single rubber-like materials. However, such materials do not replicate mechanical properties natural tissue, especially stress–strain response in higher strain (>0.1) regions. This could problematic surgeons surgeries model which does exhibit real aorta. To overcome this limitation, we developed 3D-printed, mechanically representative comprising gelatin fibers and silicone. The promising as realistic analog sinus mock TAVR Computerized tomography data was analyzed beforehand medical imaging identify specific patient’s surrounding blood vessels. A novel silicone matrix composite reinforced with designed work tested compared tissue. Such both patient-specific geometries well material tissue helpful development next-generation phantoms.
