摘要：
An atherectomy device may include an elongated, flexible drive shaft having a distal end for insertion into a vasculature of a patient and having a proximal end opposite the distal end remaining outside the vasculature of the patient, a handle coupled to the proximal end of the drive shaft for controlling the drive shaft, and a head arranged proximate the distal end of the drive shaft wherein the head may include a middle portion having a substantially uninterrupted outer surface and substantially conically-shaped first and second end portions, wherein the middle portion and substantially conically-shaped end portions all have a bore extending therethrough adapted to frictionally engage a drive shaft.
