The elongate catheter body includes a fixed jog section with a pre-set curvature and a flexible section that has a greater flexibility than a remainder of the elongate catheter body. The fixed jog section and flexible section are formed of a frame including a plurality of circumferential slits therein. Also described herein is an atherectomy catheter for use in a vessel includes an elongate catheter body, an annular cutter, and an s-shaped curved portion in the elongate catheter body.
