Information about our models

Elastrat’s in vitro models are compatible with modern imaging modalities such as digital subtraction angiography, computed tomography, magnetic resonance imaging and transcranial Doppler techniques as well, provided the appropriate circulating fluid is used. Our in vitro models are transparent and thus suitable for use with video and photographic monitoring.

Our flow models under imaging technologies are under ideal conditions to mimic physiological situations.

Elastrat’s in vitro models provide a realistic environment for the simulation of endovascular procedures. Their anatomic configuration respects human cerebro-vascular complexity and makes them excellent tools for hemodynamic studies and teaching purposes.

Simulation rehearsals on Elastrat vascular phantom models provide quality hands-on training experience for the intervening specialist. They take away the pressure by allowing trainees to learn every move of the pending intervention in a risk-free environment. A significant number of incidents in OR are due to errors resulting from inexperience, in itself the inevitable consequences of not being able to rehearse specific tasks prior to an intervention.

Elastrat simulation training minimizes the dependence on patients and alleviates the fear of learning difficult procedures. Patient-specific procedures can be practised on the simulator until the intervening specialist has mastered every detail of each individual patient’s procedure and can perform the actual intervention with the utmost confidence. All procedures are rehearsed from start to finish, thus ensuring the most realistic experience.

It is likely that, in the near future, the use of simulators such as those provided by Elastrat may become mandatory practice in surgical training programmes around the world.

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.
