Anthony P Lioi is a remarkable inventor based in Dayton, Ohio, recognized for his significant contributions to the field of biomedical engineering. With a total of four patents to his name, Lioi's work focuses on advanced blood pump technologies that aim to enhance patient care. His innovative designs reflect both functional efficiency and groundbreaking engineering principles.

Latest Patents

Among his latest advancements, Lioi has developed the "Axial Flow Blood Pump with Hydrodynamically Suspended Rotor." This innovative pump is designed for both intracorporeal and extracorporeal use, allowing it to pump blood axially through a cylindrical conduit that is placed within the patient’s bloodstream. The design integrates a pump stator mounted in the conduit and a motor stator, either internally or externally, that applies a magnetic flux. This system utilizes a rotor with permanent magnets that interact with the magnetic flux to facilitate rotational movement.

The rotor is crafted to include impeller blades which generate an axial flow of blood during its rotation. A significant feature of this design is the use of hydrodynamic bearings—formed by the blood flow itself—which radially suspends the rotor. This unique suspension method reduces the overall size of the pump and removes the need for radial bearings and purge fluids, resulting in a more compact and efficient device.

Another noteworthy patent by Lioi is the "Hydrodynamically Suspended Rotor Axial Flow Blood Pump." This innovation employs a brushless DC motor with a rotor featuring impeller blades, designed to pump blood through the central portion of the motor. Notably, a cylindrical surface on the rotor is separated by a gap from a corresponding surface on the motor stator. This gap allows for a leakage flow of blood, while the relative motion between the surfaces generates a hydrodynamic bearing that maintains rotor suspension, showcasing Lioi's ability to marry complex mechanics with practical applications.
