Navigation of guidewires and catheters during interventional procedures

Abstract

Endovascular interventions include a variety of techniques, chiefly involving guidewires and catheters, that give access to the vascular system through small incisions. It is imperative to reach the place of interest quickly and safely. By considering the fact that the composition of guidewires and catheters differ (e.g., in material, diameter, length, tip shape, stiffness, and coating), each one shows a different behavior based on its structure, and therefore the choice of instruments becomes challenging. Currently, the choice of the instruments in each procedure is often based solely on a specialist’s experience, which is not sufficient and does not always result in a successful procedure. Therefore, in this thesis, we focus on the performance of the guidewires and catheters with considering their structure.
