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.

Abstract: A medical device may include an inflatable balloon secured to a distal region of a catheter shaft. A blade assembly may extend over and be secured to the inflatable balloon. The blade assembly may include a plurality of blades and at least two rings that are adapted to secure each of the plurality of blades. Each of the rings include an inner surface adapted to be secured to the inflatable balloon and an outer surface. A number of living hinges are formed within the inner surface and the outer surface that cooperate to allow the blade assembly to move between an expanded configuration and a collapsed configuration.

Abstract: A percutaneous circulatory support device includes a housing and an impeller disposed within the housing. The impeller is rotatable relative to the housing to cause blood to flow through the percutaneous circulatory support device. The device further includes a reservoir disposed within the housing, and the reservoir carries at least one anticoagulant.

Abstract: A percutaneous circulatory support device includes an impeller disposed within an impeller housing. The impeller is rotatable relative to the impeller housing to cause blood to flow through the percutaneous circulatory support device. The device further includes a liquid carrier carrying a liquid. The liquid carrier is rotatable relative to the impeller housing to cause the liquid to form outwardly extending menisci at a plurality of apertures of the liquid carrier.
