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 a rate of hemolysis during operation of the blood pump based on an operation parameter of the blood pump.

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: Example cardiac pump systems are disclosed. An example cardiac pump system includes a cardiac pump coupled to a console. Further, the console includes a first display including a first visual representation of a first parameter of the cardiac pump system. Further, the first display includes a first status indicator and a second status indicator corresponding to the first parameter. Further, the first display is configured to display the first status indicator when the first parameter satisfies a first condition, and wherein the first display is configured to display the second status indicator when the first parameter satisfies a second condition.

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.

Abstract: Methods include capturing intravascular ultrasound images. A drive motor is used to actively drive an ultrasound transducer at a set rotation speed. A temporary sensing window is created in which the ultrasound transducer is driven with a fixed drive signal. A plurality of signals from are received the ultrasound transducer during the temporary sensing window.

Abstract: An atherectomy system is adapted for both anterograde ablation and retrograde ablation, and includes a drive coil and an atherectomy tool coupled to the drive coil, the atherectomy tool including a distal region adapted for anterograde ablation and a proximal region adapted for retrograde ablation. A proximal handle includes an actuation member adapted to be movable in a first direction to urge the atherectomy tool in an anterograde ablation direction and to be movable in a second direction to urge the atherectomy tool in a retrograde ablation direction. The atherectomy system is adapted such that the actuation member provides a similar feedback to a user regardless of whether the atherectomy tool is ablating in the anterograde ablation direction or in the retrograde ablation direction.

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: 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.

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 determine a command signal based on a value related to a speed of the motor, provide the command signal to the motor to drive the driven component, determine a value of a parameter related to operation of the blood pump based on the command signal and the value related to the speed of the motor, and output an indication a blood pump transition is recommended based on one or more determined values of one or more parameters related to operation of the blood pump.

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.
