Definition : Flexible endoscopes designed for examination of the inner lumen of vessels. They are usually introduced in the vascular system through peripheral vessels. Angioscopes usually consist of a fiberoptic lighting system surrounded by a flexible outer sheath; they are usually available in sizes from 0.8 to 3 mm in diameter and are appropriately sized for use in iliac, femoral, renal, and coronary arteries. Large-diameter angioscopes often include an irrigation channel through which a saline solution is pumped to clear blood from obstructing the view. Angioscopes may be used to evaluate the results of therapeutic procedures either in peripheral or in the coronary arteries, as well as to distinguish clots from plaque.
