What changed

USPTO granted patent US12589236B2 for an implantable total artificial heart to assignee Stichting Amsterdam UMC. The invention comprises first and second pumping chambers, an actuator between them, and a plurality of wires wound around the chambers and actuator configured to compress the chambers for fluid intake and pumping. The design emphasizes compactness, durability, and mimicking natural human tissue movement to reduce blood stress and side effects. The patent application (No. 18998258) was filed July 27, 2023, and includes 13 claims.

Medical device manufacturers developing artificial hearts, ventricular assist devices, or related cardiac implants should conduct freedom-to-operate analyses to determine if this patent claims technology in their product development pipeline. Companies should consult with patent counsel to assess potential licensing needs before commercializing similar devices. The patent grant provides the assignee exclusive rights in the United States for the claimed artificial heart technology.

Abstract

Present disclosure discloses an implantable total artificial heart. The artificial heart includes a first pumping chamber, a second pumping chamber and an actuator disposed between the first pumping chamber and the second pumping chamber. The actuator is configured to operate between a first operating state and a second operating state. Further, the artificial heart includes a plurality of first wires wound around the first pumping chamber and the actuator, and/or a plurality of second wires wound around the second pumping chamber and the actuator. Each of the plurality of first and second wires are configured to compress the first and second pumping chambers relative to operation of the actuator for receiving fluid into and pumping fluid out of the first and second pumping chamber. The configuration of the artificial heart is compact, improves durability and mimicking the natural movement of a human tissue for reducing stress on blood and resulting in fewer side effects.
