Circulatory support system

A mechanical circulatory support system comprising:

• a ventricular cuff configured for attachment to a heart of a user;
• a ventricular assist device configured for attachment to the ventricular cuff, wherein the ventricular assist device comprises a housing, a rotor, a stator assembly, and control electronics, wherein the housing defines an inlet opening and an outlet opening, wherein the housing comprises a dividing wall that delineates an inner volume that fluidly connects the inlet opening and the outlet opening, wherein the rotor is disposed within the inner volume and comprises one or more permanent magnets and centrifugal impeller blades, wherein each of the one or more permanent magnets comprises a permanent north pole and a permanent south pole, wherein the centrifugal impeller blades are configured to pump blood from the inlet opening to the outlet opening during rotation of the rotor within the inner volume, wherein the rotor and the inner volume are sized for complete magnetic levitation of the rotor within the inner volume so that blood flows through a secondary blood flow path between the rotor and the dividing wall having a secondary blood flow path gap in a range from 0.2 mm to 2.0 mm, wherein the stator assembly comprises drive coils and levitation coils, wherein the drive coils are arranged radially relative to the rotor, wherein the drive coils are operable to electromagnetically drive rotation of the rotor within the inner volume, wherein the levitation coils are arranged radially relative to the rotor, wherein the levitation coils are operable to electromagnetically levitate the rotor to control a radial position of the rotor within the inner volume, and wherein the control electronics are disposed within the housing and configured to control electrical supply to the drive coils and the levitation coils;
• a ventricular assist device input connector operatively coupled with the ventricular assist device;
• an external module comprising one or more battery cells;
• and
• a connector cable configured to operatively couple the external module to the ventricular assist device input connector, wherein the connector cable comprises a connector cable output connector and at least four connectors configured to transfer power from the one or more battery cells of the external module to the ventricular assist device input connector for powering the ventricular assist device and to transfer data between the ventricular assist device and the external module.
