Abstract

An intravascular fluid movement device that includes an expandable member having a collapsed, delivery configuration and an expanded, deployed configuration, the expandable member having a proximal end and a distal end, a rotatable member disposed radially and axially within the expandable member, and a conduit coupled to the expandable member, the conduit at least partially defining a blood flow lumen between a distal end of the conduit and a proximal end of the conduit, the conduit disposed solely radially inside of the expandable member in a distal section of the expandable member.
