A ventricular assist system comprises a ventricular state sensor and a ventricular assist device coupled to the ventricular state sensor. The ventricular state sensor includes a coil and a control module coupled to the coil. The control module is configured to drive the coil to perform eddy current induction measurement on a subject’s ventricle, and obtain at least one ventricular state information of the subject through the eddy current induction measurement. The ventricular assist device receives at least one ventricular state information to adjust the ventricular control parameters of the ventricular assist device. |
