1. A device comprising:
an indwelling catheter comprising a proximal portion and a distal portion;
an impeller assembly mounted at the distal portion of the catheter, the impeller assembly comprising an impeller housing with an impeller disposed therein, wherein the catheter distal portion and the impeller assembly are dimensioned to be navigated through a blood vessel of a patient, and a cuff comprising a distal surface wherein a proximal end of a core diameter of the impeller rotates in clearance of the distal surface of the cuff;
a motor connected to the proximal portion of the catheter;
a drive cable extending through the catheter from the motor to the impeller; and
an impermeable sleeve extending through the catheter over the drive cable, the sleeve comprising a distal seal adjacent the impeller and/or a proximal seal adjacent the motor such that a body fluid external to the impermeable sleeve is prevented from entering the impermeable sleeve and contacting the drive cable.
