Abstract
An ultrasound catheter and an ultrasound catheter system that allow an operator to identify a direction of an image acquired by a transducer. The ultrasound catheter includes: an outer sheath including an accommodation lumen extending from a proximal end to a distal end; a drive shaft movable in an inner sheath along an axial center of the outer sheath; a transducer disposed in the accommodation lumen and fixed to a distal end of the drive shaft; and a radiopaque distal end marker disposed at a distal end portion of the outer sheath, in which the distal end marker includes a marker identification portion extending along the axial center on a part in a circumferential direction, and a marker comparison portion formed in a circumferential direction or a radial direction of the outer sheath with a length and/or an arrangement different from that of the marker identification portion.
