Abstract Purpose To introduce a newly developed double lumen microballoon catheter with a side hole for intraarterial infusion chemotherapy and/or embolization. Methods and materials Seven patients with malignant tumors, for whom superselective catheterization was considered difficult or had failed, underwent intraarterial infusion chemotherapy and/or embolization with the 3.3-Fr microballoon catheter. The catheter has a double lumen and a side hole to facilitate infusion from the proximal end of the balloon. The balloon was placed on the distal side of the target artery branching site. Inflation of the balloon and occlusion of the main lumen with the tip of the occlusion device allowed for intraarterial infusion chemotherapy and/or embolization of the target artery via the side hole. Results Successful intraarterial infusion chemotherapy and/or embolization with the microballoon catheter was performed in all patients with no complications. Conclusions The newly developed microballoon catheter achieves intraarterial infusion chemotherapy and/or embolization without the need for superselective catheterization.

Keywords Double lumen microballoon catheter Side hole Intraarterial infusion chemotherapy Embolization
Introduction Intraarterial infusion chemotherapy requires superselective catheterization of the target artery [1, 2]. However, it is difficult to perform superselective catheterization in cases where the angle between the target artery and the parent artery is acute, or where target arteries branching from the parent artery are small. Accordingly, we have developed a double lumen microballoon catheter that does not require catheterization of the target artery.
Methods and materials Device specification The newly developed double lumen 3.3-Fr microballoon catheter has a side hole to facilitate infusion from the proximal end of the balloon (MicroSight, Fuji Systems, Tokyo, Japan) (Fig. 1a). The balloon is made of silicone 10 mm in length and 6 mm in nominal inflation diameter with a volume of 0.10 mL. The catheter can be inserted using a 0.014-inch guidewire. This system is equipped with a device to facilitate occlusion at the tip of the microballoon catheter (Fig. 1b). The occlusion device has a 0.018inch polyuretha
