ABSTRACT:
A fiberscope, particularly, a fiberscope adapted to be inserted into a blood vessel or the like, having a reduced diameter and reduced flow rate of flushing fluid. A cylindrically shaped inflatable balloon is disposed around the flexible tube of the fiberscope somewhat rearward of the tip end. When an observation is to be performed, the balloon is inflated to reduce the flow rate of blood in the vessel. As a result, the amount and flow rate of the flushing fluid needed to provide a clear visual field between the tip of the fiberscope and the wall of the vessel to be observed are reduced.
