Moulding Unit   The increasing accuracy of the modelizations that we conceive require the most perfect respect of the shapes, compliance and dynamics of deformation of the various cardiac cavities and vessels. Because of the difficulty to find industrials capable of making mouldings in soft materials - with respect to precise specifications - and in very reduced quantities, we created in 1995 a Moulding Unit within ESM2. We can therefore build various models of ventricle, auricle, vessels, ... which shapes and compliances are physiologic-like. These models are made of silicon, polyurethan, latex, etc...
