    Abstract: A catheter pump includes a catheter body having at least one lumen therethrough, and comprising a distal end and a proximal end. An expandable impeller assembly includes an expandable impeller and an expandable cannula coupled to the distal end of the catheter body and housing the expandable impeller, the expandable cannula comprising a substantially straight segment having a distal inlet and a proximal outlet, the substantially straight segment configured to straddle an aortic valve. The catheter body comprises a proximal vessel contact zone and a distal vessel contact zone that are each proximal to the substantially straight segment, the proximal vessel contact zone and distal vessel contact zone configured to provide a force against an aortic arch to stabilize the expandable impeller assembly across the aortic valve.

    Abstract: A catheter pump assembly is provided that includes an elongate polymeric catheter body, a cannula, and a tubular interface. The elongate polymeric catheter body has a proximal end and a distal end. The cannula has an expandable portion disposed distally of the elongate polymeric catheter body. The cannula can also have another tubular portion that is proximal to the distal portion. The tubular interface has an outer surface configured to be joined to the tubular portion of the cannula and an inner surface. The inner surface is disposed over the distal end of the elongate polymeric catheter body. The tubular interface has a plurality of transverse channels extending outward from the inner surface of the tubular interface. An outer surface of the elongate polymeric catheter body projects into the transverse channels to mechanically integrate the elongate polymeric catheter body with the tubular interface.

    Abstract: An impeller for a pump is disclosed herein. The impeller can include a hub having a fixed end and a free end. The impeller can also have a plurality of blades supported by the hub. Each blade can have a fixed end coupled to the hub and a free end. The impeller can have a stored configuration and a deployed configuration, the blades in the deployed configuration extending away from the hub, and the blades in the stored configuration being compressed against the hub.

    Abstract: A catheter pump assembly is provided. The catheter pump assembly includes a proximal portion, a distal portion, a catheter body having a lumen extending along a longitudinal axis between the proximal and distal portions, an impeller disposed at the distal portion, and a stator disposed at a downstream location of the impeller to straighten flow downstream from the impeller. The stator is collapsible from a deployed configuration to a collapsed configuration.
