Abstract
Recently, much attention has been paid to treat with the patients of intermittent claudication for minimal invasive method in the field of cardiovascular surgery. Earlier, there were only two methods of drug therapy and surgical therapy for cardiovascular diseases. However, there are some other kinds of methods such as balloon, atherectomy, laser, and stenting methods. Here, it is very important to check the vascular disease with angioscopic guidance. So, we have developed for long time, until angioscopy is available for clinical use. It was important to see clearly the inside of the vessels removing blood. So, we made a new flush channel of 1 mm inside the angioscope, with an outer diameter of 2.8 mm. With this angioscope, it was possible to check the inside of the vessels before and after laser therapy. The procedures and techniques are important for recognition of improvement before and after surgical therapy.
