摘要:
An intravascular diagnostic or therapeutic apparatus capable of removing blood in an intravascular lumen to be observed using a minimally invasive method is provided. The apparatus includes high-intensity pulsed light generating means and high-intensity pulsed light transmitting means for transmitting high-intensity pulsed light, capable of irradiating the interior of a blood vessel with high-intensity pulsed light, producing water-vapor bubbles and temporarily removing the blood in the blood vessel.

摘要:
A thin tube is provided that is inserted into a lumen of a living body so as to be used, which can detect the flexed direction of the forward end of itself with the use of a sensor disposed at such forward end upon light irradiation. The forward end of the thin tube is allowed to be flexed to a desired direction with the use of an actuator disposed at such forward end. Such thin tube for medical use is inserted into the lumen of a living body so as to be used for internal observation or internal treatment and contains a device for sensing light irradiation and/or an actuator that is operated via light irradiation at its forward end and a light transmission means, such light transmission means being used for irradiating the device and/or the actuator with light and such device or actuator functioning for monitoring and/or controlling the degree of flection of the forward end of such thin tube, is provided.
