Abstract

A new thin coronary angioscope which has a inflatable balloon at its distal tip is described in this paper. This angioscope is formed into very thin flexible catheter, less than 4F(1.33mm) in sheath outer diameter at the catheter tip. The angioscope contains two penetrated lumina which utilize for either flushing blood or manipulating of a guiding wire. A selective intracoronary visualization in left anterior descending coronary artery (LAD) and circumuflex(CX) of dogs up to 15kg in their weight were carried out during up to 20s until occurring of ST segment change of the electro-cardiogram(ECG).
