A device and method for treating a patient with total or near total occlusion is provided. The device can include a support catheter for an occlusion crossing procedure. The support catheter can include an elongate body that extends between a proximal end and a distal end. The elongate body can have a lumen for receiving and, in some cases, supporting a guidewire. The support catheter can include a crossing tip disposed on a distal portion of the support catheter. The crossing tip can have a ring structure fixedly attached to the elongate body. The crossing tip can comprise a plurality of teeth disposed on a distal-facing surface of the crossing tip. The plurality of teeth have rounded and smooth edges adapted for abrading the occlusion.
