Element Science creates medical devices to prevent sudden cardiac arrest. Its flagship product, Jewel, is a wearable external defibrillator intended to provide around-the-clock protection by monitoring the heart and delivering a life-saving shock when needed. Jewel is not yet commercially available in the U.S. This device works by continuously monitoring cardiac rhythm and, if a dangerous rhythm is detected, delivering a controlled electrical defibrillation; it is designed for use by at-risk individuals under medical guidance. The company differentiates itself by focusing on a wearable, user-friendly defibrillator and by prioritizing workforce diversity, equity, inclusion, and belonging (DEIB), as well as growth through team expansion. Element Science aims to bring Jewel to market, work with healthcare providers and insurers, increase accessibility for patients at risk of sudden cardiac arrest, and grow its market share while reducing deaths from cardiac events.

(Photo: Business Wire)SAN FRANCISCO--(BUSINESS WIRE)--Element Science, an innovative health technology company pioneering a digital wearable platform for high-risk cardiovascular patients, announced that it has received the European Union’s CE mark certification and Great Britain’s UK Conformity Assessed (UKCA) marking for its novel Patch Wearable Cardioverter Defibrillator (P-WCD) from its Notified Body, the BSI Group.The Jewel P-WCD was designed to address limitations with traditional garment-based WCDs. While these garment-based WCDs have demonstrated the ability to treat sudden cardiac arrest (SCA), a leading cause of death in the United States and in Europe, challenges related to patient comfort and compliance have resulted in avoidable deaths and limited their widespread adoption.The effectiveness of the Jewel defibrillator was confirmed in the Jewel EP Lab Study, conducted in Prague, Czech Republic, in which 16 patients experiencing ventricular arrhythmias were successfully converted to a normal heart rhythm after a single therapeutic shock. The Jewel IDE Study, a pivotal study of 305 patients presented at the American Heart Association’s 2023 Annual Scientific Sessions demonstrated significant patient compliance and protected time resulting in a high number of successful patient saves and no deaths or serious adverse events related to the device (www.ElementScience.com/ide-study/ ).Dr. Uday N
