Artificial models of cerebral aneurysms for medical training and testing of medical devices were con- structed from corrosion casts of the main cerebral arteries of a human specimen. Three aneurysms with a variety of shapes were simulated at typical locations. Rigid and soft models were made of silicone using the ``lost wax'' technique. The transparent silicone models were anatomically accurate and reproducible copies of human vascular casts. These models could be connected in a closed circuit that used an electric pump to simulate pulsatile flow.

Endovascular procedures and surgical clip application were performed under fluoroscopic or direct visual control. Surgical clipping, endoluminal coil manipulation, and consecutive hemodynamic changes were visualized by digital subtraction angio- graphy and direct observation. The model provides trainee surgeons with an understanding of clinical conditions. New medical devices, such as platinum coils, would be experimentally implanted in the model under stable conditions. These anatomically accurate and reproducible models of cerebral vas- culature and aneurysms are valuable for medical testing, training, and research.(® All rights reserved).

Computed flow dynamics simulation of a patient on a specific Head and Neck custom made model developed by Elastrat after 3D reconstruction on a flat detector angiograohic system.
Velocity stream lines and wall shear stress provided by this computation could give a significant information for the clinician about intra aneurysmal flow patterns and stimulation of aneurysm wall.

Elastrat Sàrl is a worldwide leader in the development, realization and distribution of human anatomical vascular phantoms.

Our Swiss made transparent soft or rigid silicon phantoms reproduce the anatomical vasculature with its pathologies like aneurysms or stenoses and can be trained through navigation with stents, catheters and coils. They provide a realistic environment for the simulation of endovascular procedures, pre-surgery training, studies and teaching purposes for interventionists, such as interventional cardiologists (neuroradiologists, etc.), interventional radiology-cardiologists, and interventional angiologists. 

The models promote safety through education and professional competence.
