Currently available portable DC defibrillators are cumbersome in emergency vehicles, rooms and medical aircraft. Power source and capacitive discharge systems presently severely limit reduction in defibrillation size. Proposed Phase I effort will design and develop a high capacity, high energy density rate primary battery system per unit volume. This battery will be coupled to a dc-dc converter providing 400 watt-sec of energy available for defibrillation. Total miniature portable defibrillator volume is anticipated to be 115 cubic inches, excluding electrode paddles. The primary battery has an expected 6 minute life, a 5 year shelf life, and is disposible.
