With a total of 12 patents to his name, Petre's work has advanced the understanding and treatment of cardiac conditions.
Latest Patents
Among his latest patents is a method and apparatus designed to correct for electric field non-uniformity. This innovative method involves positioning a catheter within a blood-filled chamber of a patient's heart. The catheter features an elongated body with a distal end, a proximal end, and multiple spaced electrodes. These electrodes are strategically arranged to define volume segments within the chamber. The method includes providing a constant alternating current to the electrodes, measuring the potential between pairs of electrodes, and determining correction factors to account for field non-uniformity.
Another significant patent addresses electric current leakage. This method also involves positioning a catheter in a patient's heart and utilizing alternating currents at different frequencies to measure potential differences. By analyzing these measurements, the corrected volume of each segment can be determined, accounting for variations in tissue conductance.
