Abstract

Normally since a guide wire, which diameter is 0.4 mm in minimum, is needed to induce a catheter, there is limit in adaptation area. Therefore, there is no way to induce a catheter, which diameter is less than the wire. In this study, we consider the induction of the thin catheter using acoustic radiation force instead of the wire. First we have estimated the force acting on the catheter by cantilever theory. Using the result, we have confirmed that the catheter (φ 0.2 mm, PFA) was induced to the desired area using ultrasound on multiple bifurcations as shown in the figure. From the result, it is suggested that thin catheter induction using ultrasound is possible to clinical applications.
