Abstract: A catheter pump is provided that includes a rotatable impeller and an elongate cannula. The elongate cannula has a mesh that has a plurality of circumferential members disposed about the impeller. The elongate cannula has a plurality of axial connector extending between a proximal side of a distal circumferential member and a distal side of a proximal circumferential member. The circumferential members are radially self-expandable. The cannula is configured to minimize fracture within at least in the distal zone of the mesh as the elongated cannula moves into a sheathing device.

Abstract: 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.

Abstract: In various embodiments, a catheter pump is disclosed herein. The catheter pump can include an elongated 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 can include one or more blades. The impeller blades can draw blood into the cannula when rotated. Further, an expandable support can have a mounting portion disposed on the impeller shaft distal of the impeller body and a cannula contact portion for reducing a change in tip gap due to bending of the cannula. The cannula contact portion can be disposed distal of the mounting portion.

Abstract: A catheter system includes a catheter, a recovery sheath, and an outer sheath assembly. The catheter includes an elongate body having an expandable medical device coupled with a distal end thereof. The recovery sheath is disposed around a proximal section of the catheter body, and is sized and shaped to receive the expandable medical device therein. The recovery sheath is axially movable relative to the catheter body. The outer sheath assembly includes an outer sheath disposed over the catheter body. The outer sheath includes an elongate body that extends from a proximal end to a distal end, where the proximal end of the outer sheath body is positioned distally of the recovery sheath. The outer sheath includes a retention section sized and shaped to receive the expandable medical device therein and constrain the expandable medical device in a stored configuration. The outer sheath is removable from the catheter body.
