ZOLL Medical Corporation and LIFECOR, Inc. Announce

Distribution Agreement of the LIFECOR LifeVest™ System

BURLINGTON, MA and PITTSBURGH, PA, December 30, 2002 – ZOLL Medical Corporation (Nasdaq:ZOLL) and LIFECOR, Inc., jointly reported today they have reached an exclusive distribution agreement for sales of the LIFECOR LifeVest System to hospitals for inpatient use in the United States and Canada through ZOLL’s direct sales force.  The LifeVest is the world’s first and only wearable cardioverter defibrillator, and has been approved by the FDA for patients at risk of sudden cardiac death who are not candidates for an implanted defibrillator.  As part of the arrangement, ZOLL has also agreed to make an additional investment in LIFECOR.  Prior to this investment, ZOLL owned 3.4% of LIFECOR.

The LifeVest is the first personal defibrillator that can be worn outside the body rather than implanted in the chest.  The non-invasive device continuously monitors the patient’s heart to detect life-threatening abnormal heart rhythms.  If a life-threatening rhythm is detected and the patient is unconscious, the device delivers an electrical shock to restore normal rhythm.  It can be worn by patients during an entire hospital stay, without confining them to bed.


Typically, when a potential cardiac arrest occurs in a hospital, it must be observed and reported to trigger a code team response.  The code team assembles at the patient, applies a defibrillator and, if necessary, delivers one or more shocks in an effort to restore normal rhythm.  Time elapsed prior to the first shock is the most important factor in surviving sudden cardiac arrest.  For every one minute of delay, survival chance decreases about ten percent.  More than 85% of patients shocked within a minute of the onset of cardiac arrest survive, however the time to first shock in the hospital can be significantly longer than optimal.  The advantage of the LifeVest is that the shock is delivered in less than a minute without need of a witness or code team response, greatly increasing the chance of survival.

Richard A. Packer, President and Chief Executive Officer of ZOLL stated, “The LIFECOR LifeVest contains leading edge resuscitation technology that hospitals can use as part of a comprehensive strategy to improve patient care and resuscitation.  The device will help hospitals meet the American Heart Association (AHA) recommended guidelines of three minutes to first shock.  Hospitals today are strengthening resuscitation services by adding AED’s, choosing new low energy biphasic defibrillators and expanding their capabilities.  The LifeVest can help improve survival in the 350,000 sudden cardiac arrests that occur in hospitals each year.  It perfectly complements our leading technology position in the hospital.”

Dr. M. Stephen Heilman, founder of LIFECOR, Inc., said, “This agreement will allow us to accelerate the adoption of the LifeVest system for hospitalized patients in the United States, and is an important element of our worldwide sales and marketing efforts.”
