    Abstract: In various embodiments, a catheter pump is disclosed herein. The catheter pump can include an elongated catheter body having a distal portion including an expandable cannula having an inlet and an outlet. An impeller assembly can include an impeller shaft and one or more blades. The impeller blades can draw blood into the expandable cannula when rotated. Further, an expandable support can have a mounting portion. The mounting portion can have a cylindrical member disposed on the impeller shaft and can include an enlarged distal portion at a distal end of the impeller shaft and a nose member. Further, a re-sealable member can be disposed in the enlarged distal portion of the cylindrical member and can have a path through the re-sealable member through which a guidewire can be positioned. Further, the nose member can have an aperture distal of the re-sealable member for passage of the guidewire.

    Abstract: A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen therethrough. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate. The motor assembly can also comprise a stator assembly disposed about the rotor. The motor assembly can also include a heat exchanger disposed about the stator assembly, the heat exchanger may be configured to direct heat radially outward away from the stator assembly, the rotor, and the chamber.

    Abstract: A catheter pump system is disclosed. The catheter pump system includes a catheter assembly having a proximal end, a distal end, and an elongate body extending therebetween. The elongate body defines at least an inner lumen. The catheter pump system further includes a shaft assembly extending at least partially within the inner lumen of the elongate body of the catheter assembly and defining a center lumen. The shaft assembly includes an outer filar layer, an inner filar layer disposed radially within the outer filar layer, and a polymer layer at least partially disposed between the outer filar layer and the inner filar layer and configured to inhibit a flow of fluid therethrough. The catheter pump system further include a motor assembly configured to rotate the shaft assembly.

    Abstract: An impeller for a pump is disclosed herein. The impeller can include a hub having a fixed end and a free end. The impeller can also have a plurality of blades supported by the hub. Each blade can have a fixed end coupled to the hub and a free end. The impeller can have a stored configuration and a deployed configuration, the blades in the deployed configuration extending away from the hub, and the blades in the stored configuration being compressed against the hub.

    Abstract: A catheter pump system is disclosed. The catheter pump system can include a shaft assembly and an impeller coupled with a distal portion of the shaft assembly. A motor assembly can impart rotation on the impeller through the shaft assembly, the motor assembly comprising a motor which rotates the shaft assembly. The catheter pump system can include a fluid pathway which conveys fluid proximally during operation of the catheter pump system. A seal can be disposed between the motor assembly and the impeller. The seal can be configured to impede or prevent the fluid from the fluid pathway from entering the motor assembly at least about an outer periphery of the shaft assembly. The seal can comprise an opening through which a portion of the shaft assembly extends.
