Update On USA Business Venture

Medical Monitors Limited (ASX: MDM) is pleased to advise that the recently announced USA business expansion program has commenced.

Two prestigious USA based healthcare providers have officially selected MDM's BPfone® Blood Pressure monitoring technologies.

The Veterans Affairs Medical Center in Minneapolis, in conjunction with the University of Minnesota, is evaluating patients with renal disease and hypertension using the BPfone® monitors. Veterans Affairs Healthcare is one of the world's largest integrated health care systems, caring for some 9.5 million men and women. More than 4.2 million people received care in VA health care facilities in 2003.

The successful completion of this program will provide the other 163 VA hospitals, and more than 850 ambulatory care and community-based outpatient clinics, with a model to monitor high blood pressure in patients with renal disease.

Importantly, the University of Florida, Division of Cardiovascular Medicine is also evaluating the BPfone® to determine which drugs are best used in the management of high blood pressure.

In 2002, Americans spent $12 billion on prescription drugs for high blood pressure and yet of the 58 million Americans that suffer from high blood pressure, 42 million remain uncontrolled. The number of people taking the drugs accounted for a 17 percent increase due to physicians prescribing higher price drugs over cheaper alternatives.

MDM's technologies and business model are superior to the current market offerings, and the recently announced new Company will be well placed to take a substantial share of this lucrative market in the U.S.A., UK and EU. To achieve this, the new US-based business venture has assembled a highly experienced management and sales team that boasts a combined total of more than 70 years experience in bringing premium medical technologies to market, as well as an aggressive sales force that has grown similar companies to USD $55 million in annual sales.

The Directors have full confidence in the new business venture achieving similar revenues.

MDM's unique transtelephonic (telephone transfer) technologies, which allow doctors to remotely monitor the cardiovascular health of their patients, have already been granted United States Food and Drug Administration (FDA) notification to enable marketing and sales.
