<p>[Problem] To provide a catheter which can be inserted into a small blood vessel such as a peripheral vessel and with which a sufficient field of view can be obtained. [Solution] The present invention provides: an attenuated vascular endoscopic catheter the main body of which is an optical fiber bundle and which comprises an optical lens and a radiopaque circular tip on a distal end thereof; and a flush catheter through which the attenuated vascular endoscopic catheter is led. By injecting a transparent liquid from the flush catheter, view can be widened. The vascular endoscopic catheter is capable of moving independently of the flush catheter in a longitudinal direction and enables a wide view.</p> |
