Abstract: Catheter blood pumps that include a sensor system. The pumps may include a collapsible blood conduit that defines a blood lumen. The collapsible blood conduits include a collapsible scaffold adapted to provide radial support to the blood conduit. The pumps may also include one or more impellers. One or more sensors may be arranged with respect to inflow and outflow regions of the blood lumen, the scaffold and/or the impellers.

Abstract: Catheter blood pumps that include an expandable pump portion. The pump portions include a collapsible blood conduit that defines a blood lumen. The collapsible blood conduits include a collapsible scaffold adapted to provide radial support to the blood conduit. The pump portion also includes one or more impellers. The collapsible scaffold may include portions of differing radial stiffness based on location of the one or more impellers therein.
