CATHETER HAVING IMAGING FUNCTION, AND BLOOD VESSEL INSIDE OBSERVATION SYSTEM USING SAME
A hood (2) is provided so as to extend further frontward from an outer peripheral edge portion of a distal end of a tubular body (1). The tubular body is provided with at least a channel for discharging fluid (11), a channel for imaging (12), and a bending mechanism. The hood (2) has a basic shape that is cylindrical, or a hollow conical trapezoid expanding toward the distal end, the distal end portion of the hood has an obliquely cut shape, and a hollow in the hood is opened on a distal end surface (21). A hood most distal end portion (22) located on a most distal end side in a wall portion of an outer peripheral edge of the distal end portion of the hood is bended to an inner side of the hood, thereby acting so as to allow fluid to stay.
