摘要:
An atherectomy catheter includes an elongate flexible catheter body, an elongate deflectable distal tip coupled to the catheter body at a hinge point, a rotatable cutter near the distal end of the catheter body, and a drive shaft extending within the catheter body and configured to rotate the cutter. The atherectomy catheter further includes an optical fiber extending through the drive shaft substantially on-axis with the catheter body and attached to the cutter. The optical fiber is configured to rotate with the drive shaft. The atherectomy catheter further includes a wedge configured to deflect the distal tip away from the catheter body at the hinge point upon axial movement of the drive shaft.
