  • Patent number: 10893882
    Abstract: An atherectomy system includes a handle and a drive motor that is adapted to rotate a drive cable extending through the handle and operably coupled to an atherectomy burr. A control system is adapted to regulate operation of the drive motor, including providing the drive motor with a high frequency pulse width modulation (PWM) drive signal in order to operate the drive motor. The control system monitors a motor performance parameter such as motor speed or motor torque, and when the motor performance parameter approaches a limit of a performance range, the control system adds a low frequency PWM signal to the high frequency PWM drive signal, thereby causing the drive motor to produce a tactile signal that signals to the user that the motor performance parameter is approaching the limit of the performance range.

  • Publication number: 20200397464
    Abstract: An atherectomy system includes a drive mechanism adapted to rotatably actuate an atherectomy burr and a controller that is adapted to operate the drive mechanism in a first operating mode in which the atherectomy burr is operated at a speed reference and with a predetermined torque limit. The controller is adapted to determine when the atherectomy burr becomes stuck while in the first operating mode and is further adapted to, when the atherectomy burr becomes stuck, operate the drive mechanism in a second operating mode that is different from the first operating mode.
