Headquartered in Chelmsford, MA, ZOLL Medical Corporation designs, manufactures, and markets non-invasive cardiac resuscitation solutions. These solutions include defibrillation devices with/without the pacing option, such as ZOLL's M Series, E Series, R Series, AED Plus, AED Pro, and LIFECOR, Inc.'s LifeVest Wearable Defibrillator. In addition, these solutions include a circulatory assist device called AutoPulse. The product pipeline also includes a unique fluid resuscitation product, called the Power Infuser, manufactured by Infusion Dynamics, a division of ZOLL. These devices help healthcare professionals, emergency medical service providers, and first responders to diagnose and treat cardiac arrest, wherever it occurs. Through its subsidiary, ZOLL Data Systems, ZOLL also designs and markets software that automates the collection, and the management of both clinical and non-clinical data. ZOLL has operations in the United States, Canada, the United Kingdom, Germany, France, the Netherlands, and Australia, with business partners in all of the world's major markets.
The company divides its market for non-invasive cardiac resuscitation equipment into three principal customer/geographic categories: North American hospital, North American pre-hospital (which consists of EMS or emergency medical services and public access segments), and international. The pre-hospital EMS segment consists of care providers, such as paramedics, ambulance operators, emergency medical technicians, firefighters, police, and other first-response personnel with responsibilities for public safety. The pre-hospital public access segment includes non-traditional responders to medical emergencies, who have the capability to use simplified or automated external defibrillators (AEDs). This would include security personnel, staffs in occupational settings, school personnel, and office staff. The international segment includes both hospital and pre-hospital customers outside of North America. Based on fiscal year 2007 results, the North American hospital, North American pre-hospital, other revenue (consisting of components, including electrodes) to North America, and international markets contributed 28%, 42%, 7%, and 23%, respectively, to total revenue.
