Abstract: The present disclosure relates to ultrasonic catheters including vibration wires that are positionable in a retracted position and an extended position, and their methods of use. In operation, catheters according to the present disclosure are operable in an occlusion crossing mode, in which the catheter emits ultrasonic energy with the vibration wires in the retracted position and in an atherectomy mode, in which the catheter emits ultrasonic energy with the vibration wires in the extended position, causing the vibration wires to oscillate. The vibration wires may directly or indirectly engage plaque within an artery, causing the plaque to break free from the artery wall. The oscillation of the vibration wires may be less abrasive than conventional cutting elements used in atherectomy procedures, such that catheters according to the present disclosure may cause less trauma to artery walls as compared to conventional atherectomy devices.
