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: Various aspects of the present disclosure are directed towards apparatuses, systems, and methods that system for delivering a blood pump. The system may include a blood pump that may include one or more impellers configured to cause blood to flow through the pump. The system may also include one or more guidewires. The guidewires may include one or more proximal sections and one or more distal sections, and the distal sections may have first dimensions and the proximal sections may have second dimensions, and the first dimensions may be greater than the second dimensions. The guidewires may also be tapered, geometrically shaped, have a curved profile, a combination thereof, or other configurations.

Abstract: Various aspects of the present disclosure are directed towards apparatuses, systems, and methods that may include a blood pump. The blood pump may include a magnetic field source and an impeller assembly. The impeller assembly includes an impeller and a driven magnet. The driven magnet is longitudinally offset and distally disposed relative to the magnetic field source, and the driven magnet is rotatable and longitudinally controlled by the magnetic field source. The driven magnet includes a distal side, the distal side faces the impeller. The blood pump further includes a bearing assembly near the distal side of the driven magnet.
