摘要： 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.

摘要： Catheter blood pumps that include an expandable pump portion, which include an expandable impeller housing. The housings include an expandable blood conduit that defines a blood lumen, and one or more pluralities of expandable struts extending axially from an end region of the expandable blood conduit. At least one of the pluralities of struts are non-unitary with a blood conduit at the end region.
