  • Publication number: 20210077143
    Abstract: An atherectomy system includes an atherectomy burr and a drive mechanism that is adapted to rotatably actuate the atherectomy burr and to accommodate a guidewire extending therethrough. A controller is adapted to regulate operation of the drive mechanism. A guidewire extends through the drive mechanism and an electromagnetic guidewire clamp is adapted to releasably secure the guidewire relative to the drive mechanism.

  • 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: 20200397463
    Abstract: An atherectomy system includes a drive mechanism adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. A guidewire motion detector is adapted to detect movement of the guidewire. The controller is further adapted to take action when the guidewire motion detector detects movement of the guidewire relative to the drive mechanism while the drive mechanism is operating.

  • 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.

  • Publication number: 20200315653
    Abstract: An atherectomy system includes a drive mechanism adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. The controller is adapted to calculate an estimated load torque at the atherectomy burr based upon at least one of an angular velocity of the atherectomy system and an angular acceleration of the atherectomy system. The controller is further adapted to stop or reverse the drive mechanism when the estimated load torque at the atherectomy burr exceeds a torque threshold.

  • Publication number: 20200214735
    Abstract: An atherectomy system includes a drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. In some cases, the drive mechanism includes a drive cable that is coupled with the atherectomy burr and an electric drive motor that is adapted to rotate the drive cable. The controller is adapted to regulate operation of the electric drive motor such that the drive mechanism emulates one or more performance parameters of an air turbine.

  • Publication number: 20190262032
    Abstract: An atherectomy system includes a drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. In some cases, the drive mechanism includes a drive cable that is coupled with the atherectomy burr and a drive motor that is adapted to rotate the drive cable. The controller is adapted to receive an indication of an increase in torque experienced at the atherectomy burr and is further adapted to, in response, regulate operation of the drive mechanism such that the increase in torque results in a noticeable reduction in speed of the drive mechanism such that a user of the atherectomy system notices the reduction in speed and is alerted to the increase in torque.

  • Publication number: 20190262034
    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.

  • Publication number: 20190175211
    Abstract: Medical systems and methods for making and using medical systems are disclosed. Example medical systems may include an atherectomy system configured to engage and remove plaque from walls in vessels of a vascular system. The atherectomy system may include a drive shaft, a rotational member coupled to an end of the drive shaft, a motor coupled to the drive shaft to rotate the rotational tip, and a control unit configured to control a motor state of the motor. The motor may be an electric motor. The control unit may adjust the motor state to decelerate the motor in response to detecting a jam or a stall condition. The jam or stall condition may be detected when a speed of the motor or other motor state reaches or goes beyond a threshold value as prescribed by a reference schedule.
