1. A method of forming a passage through an occlusion or lesion, the method comprising:
advancing an occlusion crossing catheter into a body lumen, the occlusion crossing catheter having an elongate body, a guidewire lumen extending within the elongate body from a proximal end of the elongate body to an opening at a distal end of the elongate body, a rotatable tip at the distal end of the elongate body, and an optical coherence tomography (OCT) sensor comprising an optical fiber coupled with the rotatable tip;
automatically rotating the rotatable tip in a first direction relative to the elongate body of the occlusion crossing catheter such that the OCT sensor rotates;
rotating repeatedly the rotatable tip alternately between the first direction and a second direction;
imaging a region of the body lumen surrounding the occlusion crossing catheter using the OCT sensor;
passing the rotatable distal tip past the occlusion or lesion in the body lumen;
advancing a guidewire past the occlusion or lesion by passing the guidewire through the guidewire lumen of the occlusion crossing catheter;
withdrawing the occlusion crossing catheter from the body lumen and leaving the guidewire in the body lumen; and
inserting an atherectomy catheter over the guidewire and into the body lumen, wherein the atherectomy catheter comprises an atherectomy catheter elongate body, an atherectomy cutter including a cutter edge, and an atherectomy catheter optical coherence tomography (OCT) imaging sensor.
