Abstract

In this paper, we propose a new prototype model of the active guide wire microcatheter whose bending has two degrees of freedom. The design and fabrication methods of this active microcatheter are described. It is 3Fr, 4Fr, 6Fr(lFr=l/3 mm) in diameter and consists of catheter tube and active guide wire with ICPF on its front end as the servo actuator. The bending motion and bending angle of the active guide wire microcatheter have been measured by application of electricity in water and in physiological saline solution. We also modeled this active microcatheter. Experimental results show that the model of the active catheter is reasonable for practical applications. By using simulators (conditions similar to those of a body cavity), we also carried out simulation experiments in vitro. The experimental results indicate that the proposed active guide wire catheter is applicable to intracavity operations.
