PROBLEM TO BE SOLVED: To provide a ureteral catheter capable of preventing a wound of a ureter caused by damage in peeling on the ureter.SOLUTION: A ureteral catheter 1 includes one or more luminal lumens including near infrared fluorescent pigment which emits near infrared fluorescent when emitting near infrared ray of wavelength of 500 nm to 1400 nm. The ureteral catheter 1 allows check of an extending state with a monitor 21 by irradiating from a light source 18 near infrared ray 17 with a specific wavelength having excellent transmissive characteristics for a biological body, and then receiving by a camera 19 near infrared fluorescent emitted from the near infrared fluorescent pigment.COPYRIGHT: (C)2014,JPO&INPIT【課題】尿管剥離時における傷害による尿管を損傷を低減できる尿管カテーテルを提供する。【解決手段】波長500nm~1400nmの近赤外線を照射時に近赤外蛍光を発する近赤外蛍光色素を含む1つ以上の内腔ルーメンを有する尿管カテーテル1によって、光源18から生体の透過性に優れた特定波長の近赤外線17を照射し、近赤外蛍光色素が発する近赤外蛍光をカメラ19で受光し、モニター21で尿管カテーテルの走行状態を確認できる。【選択図】図3C
