During Percutaneous Coronary Interventions, a guidewire is used as an initial way of accessing a specific vessel. Various experimental methods can be used to measure contact forces and frictional forces on the vessel wall. One drawback of these models is that they fail to account for the deformation of the vessel wall in response to these physical forces. Moreover, most of research has focused on catheter and blood vessel and not guidewire and catheter.

Therefore, the goal of the present study is to use experimental analysis to characterize the frictional forces and contact force between the guidewire and catheter and between the guidewire and vessel.
