1. An intravascular blood pump comprising:
an inlet area having one or more openings;
an outlet area having one or more openings;
a passage fluidically coupling the inlet and outlet areas;
a motor having a rotor and a stator, wherein the stator comprises one or more coils, wherein the stator is configured to generate a rotating magnetic field in response to receiving one or more electrical signals at the one or more coils, wherein the rotating magnetic field causes the rotor to rotate, and wherein rotation of the rotor draws blood into the one or more openings of the inlet area, channels the blood through the passage, and expels the blood through the one or more openings of the outlet area; and
a cable having a tail portion and a head portion, wherein one or more electrical conduits extend through the tail and head portions, wherein the head portion comprises one or more pads, and wherein at least one of the coils is coupled to at least one of the electrical conduits through at least one of the pads.
