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 21):
A catheter system for a catheter pump, comprising:\n an elongate catheter body having a distal portion including an expandable cannula having an inlet and an outlet, the expandable cannula having a delivery profile and an operational profile larger than the delivery profile; an expandable impeller assembly disposed in the expandable cannula and including an impeller shaft and an impeller body including one or more impeller blades, the impeller blades drawing fluid into the expandable cannula when rotated in the fluid; and a retainer sheath configured to be advanced through a vasculature of a patient to deliver the expandable cannula to a target location within the vasculature where it is advanced distally out of the retainer sheath, the retainer sheath comprising:\n a distal cannula retention zone disposed over and compressing the expandable cannula and the expandable impeller assembly into the delivery profile, and having a first resistance to separation greater than an outward force generated by the expandable cannula and the expandable impeller assembly under compression, and \n a proximal separation zone adjacent the distal cannula retention zone and disposed over the elongate catheter body, the proximal separation zone having a second resistance to a separation force, the second resistance less than the first resistance, wherein upon advancing the expandable cannula distally out of the retainer sheath, the proximal separation zone is configured to separate, under the separation force, into a first portion and a second portion disposed across a gap, the gap enabling the elongate catheter body to pass between the first and second portions to enable removal of the retainer sheath from the elongate catheter body for operation of the expandable impeller assembly.
