Abstract
Methods of performing an atherectomy using an atherectomy catheter. The atherectomy catheter may include a catheter body, a driveshaft, and a distal tip assembly. The driveshaft may include an annular cutting ring with a distal cutting edge. A long axis of the annular cutting ring can be configured to be parallel to a longitudinal axis of the distal tip assembly when the distal tip assembly is deflected with respect to the catheter body. The methods may include advancing the atherectomy catheter within a vessel lumen; axially moving the driveshaft relative to the catheter body to deflect the distal tip assembly with respect to the catheter body and radially extend the distal cutting edge of the annular cutting ring relative to the distal end of the catheter body; driving the distal cutting edge against a wall of the vessel lumen to remove tissue.
