Title: Innovations by Francis M Charbonnier

Introduction

Francis M Charbonnier is a notable inventor based in McMinnville, Oregon. He has made significant contributions to the field of defibrillation technology, holding three patents that enhance the effectiveness and safety of defibrillation procedures.

Latest Patents

One of his latest patents is titled "Defibrillation employing an impedance-corrected delivered energy." This innovation utilizes impedance-normalized delivered energy as a control parameter in defibrillation methodology. It aims to yield the highest probability of successful defibrillation while minimizing the risk of damage to the myocardium and nervous system. This control parameter is essentially independent of patient transthoracic impedance and discharge pulse waveform and duration, making it advantageous for establishing a universal defibrillation protocol. Another significant patent is the "Current-based defibrillator." This invention provides a method and apparatus for delivering a defibrillation pulse with a magnitude calculated to induce a desired defibrillation current in a patient. The patient's response to the defibrillation pulse is characterized by repeatedly sampling the patient's transthoracic impedance to a small alternating current excitation signal. The lowest sampled impedance value is normalized and multiplied by the desired current to determine the target charge level for the energy storage device, ensuring effective defibrillation.
