Latest Patents
Marjorie Rawhouser holds a patent for an "Apparatus and method for removing a pocket of air from a blood pump." This invention involves a catheter equipped with a first magnet, which is guided into a pocket of air trapped in a pumping chamber of an artificial heart. The device utilizes a probe with a second magnet, a Hall-effect sensor, an electronic circuit, and an indicator. The Hall-effect sensor generates a voltage signal that correlates with the distance between the catheter tip and the probe tip. This signal is measured by the electronic circuit and used to actuate the indicator, which alerts the user when the probe is close enough to magnetically capture the catheter tip. Once captured, the probe guides the catheter tip to the elevated portion of the pumping chamber where the air pocket is located. A vacuum-generating device attached to the catheter tube is then employed to withdraw the air from the chamber.
