Abstract
A ventricular assist device for use in a human recipient includes a housing within which a series pair of turbine pump segments and at least one set of deswirlers are operative. The series pair of turbine pump segments provides a redundancy in turn enhances the safety factor provided by the ventricular assist device. A controller is powered by a rechargeable battery and is operative to apply appropriate drive signals to the motor drives of the turbine pump segments. The battery may be implanted along with the controller to avoid the need for any external connections to the ventricular assist device. An inductively coupled battery charger for use outside the recipient's body is positioned proximate the battery charger to provide inductively coupled charging for use in driving the ventricular assist device.
