Body part: arterial ring of the brain

Special features: contains aneurysms

Use: advanced training, neurosurgical training, medical technology demonstrations

Accessories: connectors for filling with liquid

Process: 3D print from digital anatomical material with a realistic feel

The model of the Circulus Willisii is a 3D-printed replica, based on patient-specific DICOM data from a CT scan. The used tissue material is prerequisite for realistic material properties such as flexibility, wall tension and slip behavior in a moist environment. The arteries are semi-transparent and have a wall thickness of approx. 1.5 mm and an inside diameter of approx. 2 - 3 mm. There are various pathological peculiarities like aneurysms shown.
