Transluminal Dilatation of Coronary Artery Stenosis — Experimental Report

Abstract

Our modification of Dotter's method involves a double-lumen dilatation catheter for recanalizing chronic arteriosclerotic obstructions of the peripheral arteries. It seemed obvious to apply this technique to other vessels, e.g., to dilate coronary artery stenosis. In order to meet the special conditions of the heart, however, the catheter had to be reduced in size and combined with a second catheter that guides the dilatation catheter into the coronary orifice (Fig. 1). The purpose of the study was to test this catheter system in canine experiments.
