title: [Application of an angiographic catheter with side holes to intra-arterial drug infusion--improvement of drug distribution by occlusion of the catheter tip].
abstract: To improve distribution of drug by intraarterial infusion a new catheter system with sideholes, tip of which was able to be occluded by an embolus, was developed. Inner diameter of the catheter was 0.038 inch. Tip of the catheter was so smoothly tapered to 0.025 inch in inner diameter that it could be occluded by an embolus of 0.038 inch in diameter. After occlusion of the tip, drug flowed out rectangly to catheter axis from only sideholes, resulting that drug flowed out was mixtured by blood stream to make a uniform distribution of it.
