Abstract
A percutaneous circulatory support device includes a housing having a proximal end portion and a motor carried by the housing. A driving magnet is operatively coupled to the motor, and a driven magnet is operatively coupled to the driving magnet. The driven magnet includes a frustoconical shape. An impeller is disposed within the housing, and the impeller is operatively coupled to the driven magnet. The motor rotates the impeller, via the driving magnet and the driven magnet, relative to the impeller housing to cause blood to flow through the percutaneous circulatory support device and blood is inhibited from pooling in the proximal end portion of the impeller housing.
