During peripheral intravascular interventions one of the main issues is the correct deployment of the guidewire (GW) to the anatomical site which has to be treated, often supported by a microcatheter. There is a trade-off between the microcatheter flexibility and its push-ability to be able to reach the anatomical site. The catheter design has been defined with 2 transition zones. A parametric geometry has been defined in COMSOL Multiphysics®. Different type of elements have been used (3D, shell) and contact properties have been manually defined when using shell elements. This model can be used as a starting point for an optimization of the microcatheter design parameters, aiming to a maximization of the push-ability force with the catheter outer diameter as low as possible.
