Abstract
An atherectomy catheter for use in a vessel includes a catheter body, a nosecone and an annular cutter. The catheter body has a curved portion with a fixed jog section and an adjacent flexible section having a greater flexibility than a remainder of the catheter body. The fixed jog section and the flexible section include a frame having circumferential slits arranged in rows and in a circumferentially offset pattern. The circumferential slits of the flexible section are configured to allow the flexible section to passively bend in multiple directions during positioning of the catheter body within the vessel. The fixed jog section further includes a longitudinal spline having a pre-set curvature. The nosecone is attached to a distal end of the catheter body and includes a cutting window. The annular cutter configured to rotate with respect to the catheter body and positioned within the cutting window.
