Abstract: An atherectomy system includes a user interface that an operator engages with in order to indicate requested movement of a drive assembly. One or more sensors are adapted to ascertain one or more conditions of the drive assembly and to output one or more condition signals to a controller that is operably coupled with the operator assembly and the drive assembly. The controller is adapted to receive the request signal from the operator assembly and the one or more condition signals, to determine a command signal in response to the received request signal and the received one or more condition signals, and provide the command signal to the drive assembly. The drive assembly is adapted to move relative to the advancer assembly in accordance with the command signal.

Abstract: A circulatory support system may include a blood pump and a controller. The blood pump may include a driven component and a motor in communication with the driven component and the controller to drive the driven component to pump a blood flow through the blood pump. The controller may be configured to receive a value of a circulatory parameter related to blood flow through a patient, determine a value of a command signal based on the received value, and output the command signal to the motor to drive the driven component at a speed configured to achieve the value of the circulator parameter related to blood flow through the patient.

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.

Abstract: A percutaneous circulatory support system includes an impeller and a motor operably coupled to the impeller. A controller is operably coupled to the motor, and the controller is configured to: drive the motor, the motor thereby rotating the impeller to cause blood to flow; determine that an operating parameter of the system deviates from a symmetric waveform; and in response to determining that the operating parameter deviates from the symmetric waveform, provide an alert of aortic valve insufficiency.

Abstract: An atherectomy system includes an electric drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the electric drive mechanism. The controller regulates operation of the electric drive mechanism in accordance with a power input limit value that limits how much power can be put into an atherectomy burr and an energy input limit value that limits how much energy can be put into the atherectomy burr. The controller may also regulate operation of the electric drive mechanism in accordance with a dynamic torque limit.

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.

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.

Abstract: A circulatory support system may include a blood pump, one or more sensors, and a controller in communication with the one or more sensors. The blood pump may include a driven component and a motor in communication with the driven component to drive the driven component to pump a blood flow through the blood pump. A sensor of the one or more sensors may be configured to sense a value related to a speed of the motor. The controller may be configured to provide a command signal to the motor to drive the driven component and determine one or more values related to the blood flow pumped through the blood pump based on the value related to the speed of the motor and the command signal.

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.

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.
