Abstract:
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.

Claim (Index 31):
A method of advancing a catheter pump to a target location within a vasculature of a patient, the method comprising:\n disposing an expandable impeller assembly in an expandable cannula; disposing an elongate catheter body in a proximal separation zone of a retainer sheath and the expandable cannula in a distal cannula retention zone of the retainer sheath to compress the expandable cannula and the expandable impeller assembly from an operational profile into a delivery profile smaller than the operational profile, the distal cannula retention zone adjacent to the proximal separation zone and having a first resistance to separation greater than an outward force generated by the expandable cannula and the expandable impeller assembly under compression; advancing the retainer sheath through the vasculature of the patient to deliver the expandable cannula to the target location; advancing the expandable cannula distally out of the retainer sheath at the target location; separating, under a separation force, the proximal separation zone of the retainer sheath into a first portion and a second portion disposed across a gap, the proximal separation zone having a second resistance to the separation force, the second resistance less than the first resistance; and passing the elongate catheter body between the first portion and the second portion to remove the retainer sheath from the elongate catheter body for operation of the expandable impeller assembly.
