TASER to introduce the much-anticipated XREP wireless 12-gauge Neuro Muscular Incapacitation (NMI) projectile at the annual TASER® Tactical Conference on July 9, 2007 in Chicago. The Conference, normally restricted to active duty law enforcement and military officers, will include an open session for media to attend the keynote address by Tom and Rick Smith, Chairman and CEO respectively, at the conference’s opening from 9:00 to 10:30 a.m. “The Wireless eXtended Range Electronic Projectile (XREP) is truly a revolutionary technology breakthrough, culminating five years of intensive research and development and a dream that began 14 years ago with the founding of TASER International,” said Rick Smith, CEO. “The XREP introduces not only amazingly miniaturized TASER technology, but groundbreaking flight stabilization and microprocessor-controlled intelligent electrode selection technologies – in a package that weighs only 14 grams, or half an ounce. The XREP projectile is, by an order of magnitude, the most sophisticated weapon system ever launched from a 12-gauge shotgun platform. XREP product images, video demonstrations, and public specifications will not be released until the keynote presentation. Limited previews of advanced features will be posted on TASER International’s website at www.TASER.com/XREP - with the keynote address and full product features being released on July 9. The Company plans to release the XREP into a field test for 6 to 12 months starting in the fall of 2007, with full release of production in 2008 upon completion of the field trial phase. Law enforcement, military, and press can sign up to attend the TASER Tactical Conference (Media may attend the keynote XREP demonstration only) at www.TASER.com/XREP.

A study by the Cleveland Clinic reported that a standard electrical discharge from a TASER® X26 electronic control device (ECD) does not induce ventricular fibrillation. The study used 13 anesthetized adult pigs according to Dhanunjaya Lakkireddy, M.D., an electrophysiology (EP) fellow at the Cleveland Clinic during the study and now clinical assistant professor of medicine at the University of Kansas Hospital and a practicing Cardiac Electrophysiologist with the Bloch Heart Rhythm Center. It assessed the vulnerability for ventricular fibrillation (VF) induction by a standard five-second TASER X26 discharge at varying locations on the body surface in a pig model. VF was never induced with the standard one-time TASER X26 application at any of the five positions. The study concluded that even with the worst-case locations, with probes plunged fully towards the heart, the researchers were never able to induce VF in 34 kg (76 lb) pigs at standard strength and duration of application. “A standard five-second TASER ECD application is unlikely to cause life-threatening arrhythmias, at least in the normal heart, irrespective of the position of application,” said Dr. Lakkireddy.

According to the peer reviewed Cleveland Clinic study as published in Europace, by the European Society of Cardiology®, a standard electrical discharge from a TASER® X26 electronic control device (ECD) does not affect the integrity of implantable pacemakers and defibrillators and did not trigger an implantable cardioverter defibrillator (ICD) shock in devices programmed to the standard non-committed shock delivery mode. As is well known, implantable cardiac devices are sometimes susceptible to malfunction as a result of electromagnetic interference (EMI). EMI can result in many undesirable consequences, including damage to internal circuitry, oversensing, undersensing, failure to pace, failure to capture, power on reset, triggering of elective replacement indicators or inappropriate defibrillation shocks. This study evaluated the immediate effects of TASER X26 discharges on the function of various models of pacemakers and ICDs from the three major manufacturers. A small 50 lb (28 kg.) anesthetized adult pig served as an animal model. It concluded that the TASER X26 discharges do not affect the short-term functional integrity of implantable pacemakers and defibrillators even when the darts are placed in a manner to surround the implanted device. Also, the standard ECD application duration of five seconds should not trigger an ICD shock in devices programmed to the standard non-committed shock delivery mode. “A standard five-second TASER X26 application does not affect the functional integrity of pacemakers and defibrillators,” said Dr. Lakkireddy, who was the primary investigator for this study. Dr. Lakkireddy was an electrophysiology fellow at the Cleveland Clinic at the time of the study and is now a clinical assistant professor of medicine at the University of Kansas Hospital and a practicing cardiac electrophysiologist at the Bloch Heart Rhythm Center in Kansas City, KS.
