Abstract Biomodels made of poly(vinyl alcohol) (PVA) are demanded because they can represent the geometries and mechanical properties of human tissues realistically. Injecting and molding, commonly used in three-dimensional (3D) modeling, help to rep

Tube-shaped blood vessel models that mimic their geometries and mechanical properties can deliver reliable and realistic behavioral information such as deformation and rupture during procedures such as insertion of medical devices. Thickness of vesse

The mechanisms underlying the growth and rupture of aneurysms are poorly understood. Although the wall shear stress (WSS) in elastic aneurysm models is examined using fluid-structure interaction (FSI) simulations, it has not been sufficiently validat

Biomodels, which are models of tissues such as blood vessels, have recently come into high demand for surgical training or medical device assessment use. Since the stiffness of blood vessels is not uniform, reproducing this nonuniformity would be adv

Intravascular surgery using catheters, such as coil embolization and stent placement, is a minimally invasive treatment. However, doctors need to be skillful to perform precise intravascular surgery. It is expected that displacement of the blood vess

Phantoms for ultrasonography have been widely used to evaluate new medical devices and improve skills of new physicians. Several kinds of phantoms for ultrasonography have already been developed to keep pace with the progress of developments in ultra

In recent years, endovascular coil embolization for cerebral aneurysms has been used as an effective and minimally invasive treatment. However, the therapeutic effects might be deteriorated due to the incorrect positioning of the coils in the aneurys
