    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 disposed on the impeller shaft distal of the impeller body. The mounting portion can have a cylindrical member disposed on the impeller shaft and can include an enlarged distal portion having an inner diameter greater than the enlarged diameter at a distal end of the impeller shaft. 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.

    Abstract: A catheter pump system includes a catheter assembly having a proximal end, a distal end, and an elongate body extending therebetween. The catheter pump system also includes a motor assembly including a shaft assembly extending at least partially within the elongate body of the catheter assembly. The shaft assembly is configured to rotate about an axis. The catheter pump system further includes a flow diverter housing defining a chamber and a fluid pathway through which a proximally-conveyed fluid flows. The shaft assembly extends outward from the chamber into an inner lumen of the elongate body. The catheter pump system also includes a seal configured to extend around and engage the shaft assembly to inhibit fluid within the elongate body of the catheter assembly from entering the chamber at least about an outer periphery of 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 is disclosed herein. The catheter pump can include a catheter assembly that comprises a drive shaft and an impeller coupled to a distal end of the drive shaft. A driven assembly can be coupled to a proximal end of the drive shaft within a driven assembly housing. The catheter pump can also include a drive system that comprises a motor and a drive magnet coupled to an output shaft of the motor. The drive system can include a drive assembly housing having at least one magnet therein. Further, a securement device can be configured to prevent disengagement of the driven assembly housing from the drive assembly housing during operation of the pump.

    Abstract: A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen in which waste fluid flows proximally therethrough during operation of the catheter pump. 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 rotor including a longitudinal rotor lumen therethrough. The motor assembly can also comprise a stator assembly disposed about the rotor. During operation of the catheter pump, the waste fluid flows from the lumen into the chamber such that at least a portion of the waste fluid flows proximally through the longitudinal rotor lumen.

    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. The catheter pump system can include a motor assembly, the motor assembly comprising a chamber and a shaft-driving portion disposed in the chamber. The shaft-driving portion can be configured to impart rotation to the impeller through the shaft assembly. The chamber can be filled with a gas that at least partially surrounds the shaft-driving portion. A fluid pathway can convey fluid proximally during operation of the catheter pump system. A bypass pathway can be in fluid communication with the fluid pathway, the bypass pathway configured to direct at least a portion of the fluid to bypass the chamber.
