Abstract
An OCT catheter and a method for manufacturing the OCT catheter, with which the operation time, manufacturing cost, and the risk of breakage of a spliced portion between a short-length fiber and an optical fiber contained in an interior member can be reduced, are provided. An OCT catheter includes an interior member that contains an optical fiber and that is to be inserted into a body, a metal tube that guides the interior member, and an optical connector. The optical connector includes a ferrule assembly including a short-length fiber and a ferrule fixed to one end of the short-length fiber, and is connectable to a rotary joint of an OCT system. The other end of the short-length fiber and one end of the optical fiber contained in the interior member are fusion-spliced together to form a spliced portion. The spliced portion is disposed in the metal tube.
