摘要： An atherectomy system includes a drive assembly and an advancer assembly. The drive assembly, which may be reusable, includes a drive motor having an output shaft and a first coupler segment that is secured relative to the output shaft. A controller may be adapted to regulate operation of the drive motor. The advancer assembly, which may be single use, includes a flexible drive cable that is adapted to be releasably securable to the first coupler segment. The advancer assembly includes gearing that is secured within the advancer assembly and is operably coupled with the flexible drive cable. A burr catheter is coupled with and extends distally of the gearing. The advancer assembly is adapted to enable relative translation of the burr catheter in order to advance and withdraw an atherectomy burr rotatably secured to a distal end of the burr catheter.
