In our previous studies, many experiments using pseudoblood vessels with an inner diameter of ≤6 mm have been carried out assuming that the catheter is inserted in a femoral artery. In recent years in Japan, however, along with the trends of reducing the burden on patients and the down-sizing of catheters, in more than half of the cases, catheters are inserted in radial arteries with in-ner diameters of 2.0–3.5 mm for the treatment of dysfunctional coronary arteries. The purpose of this study was to develop a small active catheter so that the catheter can navigate in a radial ar-tery. The effectiveness of the catheter was confirmed by the driving experiment using silicon tubes with inner diameters of 2.5–3.0 mm and an endovascular surgery simulator.
