EP Sciences, LLC is a New York-based company founded in 2011 by the Coridea medical device incubator. The company is developing a novel waveform to reduce the severe pain associated with implantable cardioverter defibrillator (ICD) shocks in patients at risk of sudden cardiac arrest. While roughly 800,000 Americans have an implanted defibrillator, the fear of an initial shock, post-traumatic stress from having experienced a shock, and the risk of receiving inappropriate shocks greatly limit the patient and physician acceptance of ICD therapy. EP Sciences aims to improve the tolerance of ICD shocks to better assist patients suffering from ventricular fibrillation and other life-threatening cardiac arrhythmias.
