摘要： Sensors for catheter pumps are disclosed herein. The catheter pump can include a catheter assembly comprising a catheter and a cannula coupled to a distal portion of the catheter. The cannula can have a proximal port for permitting the flow of blood therethrough. The catheter assembly can include a sensor to be disposed near the proximal port. A processing unit can be programmed to process a signal detected by the sensor. The processing unit can comprise a computer-readable set of rules to evaluate the signal to determine a position of the cannula relative to an aortic valve of a patient.

摘要： A heart pump includes a cannula having a sidewall defining a longitudinal blood flow passage and a plurality of outlets extending through the sidewall. A rotatable impeller hub includes at least one impeller blade, wherein the at least one impeller blade is shaped to convey blood through the blood flow passage toward the plurality of outlets when the impeller hub is rotated at an operational speed. A diffuser defines an outer, flow directing surface having a geometry that is configured to control at least one property of the conveyed blood prior to flowing through the plurality of outlets.

摘要： 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.

摘要： A catheter pump assembly is provided that includes an elongate body, an elongate flexible shaft disposed in the elongate body, and an impeller coupled with the distal end of the elongate flexible shaft. The drive system includes a drive component, a motor and a tension member. The tension member is coupled with the motor and the drive component and to cause the drive component to rotate, and thereby to cause the impeller to rotate.

摘要： A system for coupling a motor assembly to a control console is disclosed. The motor assembly is configured to drive a percutaneous heart pump. The system includes a motor coupling comprising a first end having an electrical connection and a fluid connection coupled to a respective electrical conduit and fluid conduit of the motor assembly, and a second end spaced apart from the first end including an interface coupling coupled to the electrical conduit and fluid conduit. An interface member is configured to be removably coupled to the control console, the interface member comprising a corresponding connector coupleable to the interface coupling of the second end of the motor coupling, wherein the interface member is configured to provide a sterile attachment of the fluid conduit to the control console.

摘要： 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.

摘要： 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.
