    Abstract: An atherectomy system includes an advancer assembly and a drive assembly that is adapted to translate relative to the advancer assembly. A control knob extends from the drive assembly such that translating the control knob results in the drive assembly translating relative to the advancer assembly. A drive shaft is operably coupled with the drive assembly, the drive shaft translating relative to the advancer assembly as the drive assembly translates relative to the advancer assembly. A feedback modifier is operably coupled between the drive assembly and the advancer assembly and is adapted to provide a user of the atherectomy system with similar feedback via the control knob regardless of whether the user is moving the drive assembly in an anterograde ablation direction or a retrograde ablation direction.

    Abstract: 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.

    Abstract: An atherectomy system includes a drive mechanism adapted to rotatably actuate an atherectomy burr and a control system that is adapted to regulate operation of the drive mechanism. The drive mechanism may include a drive cable that is coupled with the atherectomy burr and a drive motor that is adapted to rotate the drive cable. The control system includes a drive module adapted to provide an operational signal to operate the drive mechanism, a monitoring module adapted to monitor operation of the drive mechanism and to determine if the drive mechanism is operating within a predetermined range and an excitation module that is operably coupled to the drive mechanism and is adapted to provide haptic feedback to a user of the drive mechanism if the monitoring module determines that the drive mechanism is not operating within a predetermined range.
