1. A system for intravascularly implanting a blood pump assembly into a patient, the system comprising:
an elongated delivery dilator having a first end portion, a second end portion, and a lumen extending between the first end portion and the second end portion, wherein the elongated delivery dilator is configured to advance over a guidewire positioned within the patient's vasculature and to extend through the patient's vasculature between a first blood vessel and a second blood vessel; and
a pump assembly including:
an expandable member configured to be positioned in a patient's descending aorta to provide circulatory support to the patient's heart; and
a driveline having a second end region connectable to the expandable member and a first end region connectable to the second end portion of the elongated delivery dilator.
