Project Summary/Abstract We propose the development and evaluation of a novel implantable low-energy device, using an innovative low-energy approach, to achieve tolerable, nearly pain free treatment of atrial fibrillation. Atrial fibrillation (AF) is a global epidemic. Approximately 33.5 million individuals are affected worldwide and close to 5 million new cases occur each year costing the US healthcare system between $6 and $26 billion annually. Atrial fibrillation is a progressive disease with many patients first developing paroxysmal atrial fibrillation (PAF). Left untreated, PAF can progress to persistent or permanent AF. Because of rapid changes in the atria after AF onset, a therapy to treat AF soon after onset may slow the progressive nature of atrial fibrillation. There exists great enthusiasm in the medical community for AF interventions. Limitations in both pharmacologic and other device-based efforts to treat AF have been disappointing. An effective atrial defibrillator was previously developed; however, it was abandoned due to pain associated with shocks. A tolerable, nearly pain-free, device-based AF therapy approach would address a major unmet medical need. Prior canine and early stage human studies have observed that the proposed therapy approach significantly lowers the energy required for atrial defibrillation. The goal of this proposed direct to phase II project is to develop a prototype AF therapy device and evaluate its performance in a human clinical trial under FDA IDE.
