Element Science

Executive Summary

Element Science is a San Francisco-based medical technology company developing wearable cardioverter defibrillators (WCDs) for patients at risk of sudden cardiac arrest. Its flagship product, the Jewel Patch WCD, aims to replace traditional vest-based defibrillators with a more comfortable, discreet, and adhesive patch form factor. The device continuously monitors heart rhythms and delivers a life-saving shock if a dangerous arrhythmia is detected. Element Science has conducted clinical trials to demonstrate the safety and efficacy of the Jewel Patch, and the company is seeking FDA clearance to market the device in the United States. The potential market is substantial, as current WCDs are bulky and associated with poor patient compliance; an adhesive patch could significantly improve adherence and outcomes. The company has raised venture capital funding and is positioned to address an unmet need in cardiac care. If approved, the Jewel Patch could capture a significant share of the WCD market, which is estimated at several hundred million dollars annually.
