Apparatus, system and method of guiding tip bushing for rotary atherectomy

摘要

A high-speed rotating atherectomy device for incising a stenosis of an artery having a predetermined diameter comprises a guidewire, a flexible, elongated rotatable member having a proximal end and a distal end and being advanceable along a guidewire A drive shaft, and a guide member fixedly attached to the drive shaft. When the guide member advances to the stenosis, when the drive shaft is rotated, the guide member creates a guide hole.
