  • Endoscope apparatus for inside wall of blood vessel
    Patent number: 6582359
    Abstract: An endoscope apparatus has a side view endoscope 10 for side viewing an object in a radial direction of a distal end constitutional portion 14 and a balloon catheter 40. With an insert portion 13 of a side view endoscope 10 inserted in an insert tube 41 of the balloon catheter 40, the balloon catheter 40 is inserted into a blood vessel B. The insert tube 41 is provided at its distal end with a transparent balloon 42. This balloon 42 encloses the distal end constitutional portion 14. By feeding air (fluid) to this balloon 42, the balloon 42 is expanded so as to be urged against an inside wall of the blood vessel B. This causes the blood to be discharged between the inside wall of the blood vessel B and the balloon 42, thus enabling to observe the inside wall of the blood vessel B through the side view endoscope 10.
