Ernest WhitonChief Financial OfficerZOLL Medical Corporation+1 (978) 421-9655 MEDIA CONTACT: Diane EganZOLL Medical Corporation+1 (978) firstname.lastname@example.org FOR IMMEDIATE RELEASE ZOLL Medical Receives International Regulatory Approvals for Two Resuscitation Products Wednesday, June 15, 2005 – CHELMSFORD, MASS.—ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and software solutions, announced today that it has received international regulatory approvals for two products: the Power Infuser® from ZOLL’s Infusion Dynamics division, and the ZOLL AutoPulse™ Non-invasive Cardiac Support Pump.The Power Infuser has been granted approval by the Canadian Regulatory Agency, Health Canada Therapeutic Products Directorate (HCTPD), to begin marketing in Canada. In addition, the Power Infuser is now labeled with the CE Mark, allowing for the sale of the miniature fluid resuscitation pump in the European Union. To qualify for the CE Mark, the Power Infuser was tested to international standards for electrical safety and electromagnetic compatibility. This testing is in addition to rigorous electromagnetic, climatic, altitude, vibration, and human-factor tests previously conducted by the U.S. Army and U.S. Air Force, which qualified the device for use in military aircraft.Additionally, the AutoPulse has received approval from Australia’s Therapeutic Goods Administration (TGA), allowing for the sale and marketing of the AutoPulse to help treat sudden cardiac arrest in that country. The AutoPulse already has the CE Mark for Europe, as well as regulatory approvals in Canada and New Zealand.“These additional approvals expand the markets where ZOLL can sell its advanced resuscitation products, and should help to continue the progress made in international sales last quarter,” said Richard A. Packer, President and Chief Executive Officer. “ZOLL remains focused on advancing the practice of resuscitation worldwide by offering a range of products that work together and help healthcare professionals save lives.” About the ZOLL AutoPulse The AutoPulse™ Non-invasive Cardiac Support Pump is revolutionary in its design and potential to offer better outcomes. As an adjunct to CPR efforts, the AutoPulse can do chest compressions that humans can’t possibly do, while moving much more blood, more effectively,1-5 to the heart and brain. The device is comprised of a backboard and a simple LifeBand™ that fastens across a victim’s chest. The AutoPulse compresses the entire chest in a unique, consistent “hands-free” manner, moving more blood than can be moved during manual CPR.2-4 About the Power Infuser ZOLL’s Infusion Dynamics division manufactures and markets the Power Infuser®, a small, lightweight, easy-to-use device, which provides highly controlled, rapid delivery of intravenous (IV) fluids to trauma victims. Using a patented mechanism, the pump delivers controlled fluid boluses at rates up to 100 ml per minute—several times that of conventional infusion pumps. Yet, it is small enough to strap to a patient’s arm.Primarily sold to the military today, this product has applications in aeromedical transport, EMS, and emergency room settings. Infusion Dynamics and the Walter Reed Army Institute of Research in Silver Spring, Md., jointly conceived the Power Infuser to treat wounded soldiers on the battlefield and in transport.
