9. An implantable blood pump comprising:
-
a housing defining an inlet opening and an outlet opening; a dividing wall within the housing defining a blood flow conduit, the blood flow conduit extending between the inlet opening and the outlet opening of the housing; a rotary motor including a stator and a rotor, the stator being disposed within the housing circumferentially about the dividing wall such that the blood flow conduit extends through the stator, the stator being disposed circumferentially about at least a part of the rotor and being positioned relative to the rotor such that in use blood flows within the blood flow conduit through the stator before reaching the rotor, and the rotor having permanent magnetic poles for magnetic levitation of the rotor; and a molded interconnect device carrying a Hall sensor, the Hall sensor being configured to transduce a position of the rotor, wherein the molded interconnect device comprises one or more integrated electronic circuit traces that are configured to electrically connect the Hall sensor with a printed circuit board of the rotary motor, and wherein the molded interconnect device is mounted to the printed circuit board. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of assembling a blood pump, the method comprising:
-
assembling a motor stator and control electronics in a housing circumferentially about an internal dividing wall, the internal dividing wall defining the a blood flow conduit that extends from an inlet opening to an outlet opening of the housing, the stator being assembled in the housing such that the blood flow conduit extends through the motor stator; disposing a magnetically-levitated rotor within the blood flow conduit and surrounded by the stator such that impeller blades carried by the rotor are downstream of the rotor from the inlet opening, and such that, in use, the impeller pumps blood from the inlet opening to the outlet opening through the stator; mounting a molded interconnect device between pole pieces of the motor stator onto a printed circuit board of the motor stator, wherein the molded interconnect device carries a Hall sensor that is configured to transduce a position of the rotor, and wherein the molded interconnect device comprises one or more integrated electronic circuit traces; and electrically connecting the Hall sensor with the printed circuit board using the one or more integrated electronic circuit traces and electrically connecting the printed circuit board with the control electronics. - View Dependent Claims (18)
