    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： A blood pump, such as an axial flow pump, having a pump housing, the pump housing defining a flow path and having a tapered portion adjacent to an outlet, tapering toward the outlet, an outflow cannula connected to the outlet of the pump housing, and an impeller and diffuser, disposed in the pump housing, the diffuser having a tapered body corresponding to the tapered portion of the pump housing, the diffuser body having at least one vane extending therefrom, the vein tapering in the same direction as the diffuser body. The present invention also includes a method of manufacturing the blood pump and a method of implanting the blood pump.
