    摘要: A catheter pump assembly is provided that includes an elongate body assembly, a shaft, and an impeller. The assembly has a proximal end, a distal end and at least one lumen extending therebetween. The shaft is disposed at least partially within the elongate body, e.g., in the at least one lumen, and journaled for rotation. The impeller is coupled with a distal portion of the shaft. The impeller is configured to be rotated to induce flow of blood when the impeller is placed in fluid communication with a source of blood. An inflatable balloon brace is disposed on an outer surface of the catheter pump. The inflatable balloon brace is spaced proximally of the impeller and has a low profile configuration for delivery through the vasculature and an expanded configuration for disposing (e.g., position and/or orienting) the impeller within the source of blood.

    摘要: A catheter system for a catheter pump is disclosed. The system can include an elongate catheter body having a distal portion including an expandable cannula having an inlet and an outlet. The expandable cannula can have a delivery profile and an operational profile larger than the delivery profile. An impeller assembly can include an impeller shaft and an impeller body. A sheath can have a cannula retention zone disposed over the expandable cannula and a separation zone. The cannula retention zone can have a first configuration adapted to retain the expandable cannula in the delivery profile. The system can be adapted to separate the separation zone into a first portion and a second portion disposed across a gap. The gap can enable the elongate catheter body to pass between the first and second portion so that the sheath can be removed from the elongate catheter body.

    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 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.

    摘要: A fluid handling system includes a console configured to connect with a first electrical interface that is configured to connect to a plurality of components of the fluid handling system, the console including a second electrical interface configured to connect with the first electrical interface, a display, and one or more hardware processors. A control system includes the one or more hardware processors and a non-transitory memory storing instructions that, when executed, cause the control system to: detect an electrical signal from a first component of the plurality of components of the fluid handling system responsive to a caretaker performing a first instruction; determine a system state of the fluid handling system based at least in part on the electrical signal from the first component; compare the system state with a predetermined state condition corresponding to said first instruction; and output an indication on the display of the system state.

    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.
