Abstract: A ventricular assist device for use in a human recipient includes a housing within which a series pair of turbine pump segments are operative. The series pair of turbine pump segments provides a redundancy which 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 arty 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.

Abstract: A high-frequency transvalvular blood pump (10) for temporary cardiac assist devices provides suction to decompress the ventricular cavity (18) during both systole and diastole. The intake end (30) of the pump (10) is connected to a cannula (12) which is inserted into the ventricular cavity (18) through the aortic valve (16), and which has an intake opening (22) at its distal end. The intake (30) and outflow (32) ends of the pump (10) are closed, respectively, by one-way valves (40, 42) which allow blood flow only in the direction of body perfusion. The pump (10) itself consists of a stiff barrel (26) whose interior volume can be alternately reduced and expanded by a flexible membrane (28) controlled by pneumatic or hydraulic pressure from extracorporeal structure through a percutaneously inserted lumen (24).

Abstract: A prosthetic heart valve either of the mechanical type or the bio prosthetic type, comprises a tubular or cylindrical frame element, a plurality of injectors, a suturing member surrounding the tubular or cylindrical frame element, tether lines to secure the device during diastolic filling but more predominantly during systolic contraction that creates a vortex effect with externally supplied pressurized fluid injected angularly within a transport structure is provided. Such a unit is utilized to accelerate the hemodynamics, reduce the energy required for said transport or both. The annular frame is designed to allow a passageway for blood flow and regulating flow during systolic contraction. Such a result is achieved through the introduction of pressurized fluid (blood) via a plurality of injectors situated evenly around the circumference of the subject tubular or cylindrical unit, and angled uniformly for an even pressure injection of fluid within the conveyance component thereof.
