Medtronic Receives FDA Approval for Guardian® Real-Time Continuous Glucose Monitoring System


System Provides Patients Superior Protection than Fingersticks Alone

MINNEAPOLIS — July 17, 2006 — Medtronic, Inc. (NYSE: MDT) today announced that the U.S. Food and Drug Administration (FDA) has approved the Guardian® REAL-Time System, a doctor-prescribed continuous glucose monitoring (CGM) system for improved diabetes management. Especially well suited for diabetes patients who frequently monitor their glucose levels, the Guardian REAL-Time System is intended to help protect patients by alerting users to high and low glucose levels. The REAL-Time information and retrospective glucose trend data provided by the Guardian REAL-Time System are designed to help patients more tightly control glucose levels. Improved glucose control has been shown to significantly reduce the likelihood of certain long-term complications, including blindness, kidney failure, amputation, impotence, and heart disease. The system will be available nationwide by the end of this year.

“The Guardian REAL-Time System is the culmination of more than seven years of research into continuous glucose monitoring technology,” said Robert Guezuraga, president of the Diabetes business at Medtronic. “With more than 2,400 patient years of glucose monitoring, and more than 470,000 glucose sensors shipped, Medtronic is leading the way with the newest generation in continuous glucose monitoring technology.”

Unique features only available with the Guardian REAL-Time System include predictive and rate-of-change alarms and expanded trend graphs. In addition to high and low glucose alerts, these new predictive alarms are designed to warn patients of significant glucose changes well before they become dangerous. Comprehensive trend graphs show the effect of diet, exercise, medication, and lifestyle on glucose values in three, six, 12, and 24 hour increments. All glucose data can be downloaded using the Medtronic CareLink® Therapy Management Software.

The Guardian REAL-Time System glucose sensor is a tiny electrode inserted under the skin that measures glucose levels in the interstitial fluid found between the body’s cells. The sensor is connected to a transmitter that sends glucose readings every five minutes to a monitor, which displays up to 288 readings a day – nearly 100 times more information than conventional monitoring.* This additional information provides better protection against frequent glycemic highs and lows, and empowers patients to be more proactive about their diabetes management. CGM technology identifies four-times more glucose excursions requiring therapy adjustment than just fingerstick monitoring alone. REAL-Time alarms help reduce the duration of hypoglycemic (low blood sugar) episodes by 48 percent.

The Guardian REAL-Time System is indicated for continuous or periodic monitoring of glucose levels of adults (ages 18 and older) with diabetes mellitus for the purposes of improving diabetes management. The glucose sensor is typically discarded and replaced after three days of use. All therapy adjustments should be based on measurements obtained using a blood glucose meter (fingerstick measurement). The device requires one calibration point every 12 hours.

Current standards for assessing glucose control include A1C tests and fingerstick measurements, yet both have limitations. An A1C test, which measures glucose control during a three-month period, is important for long-term management, but it is only an average and does not reveal day-to-day glucose fluctuations that can harm the body. In turn, fingerstick measurements only reveal a glucose value at a single moment in time. As a result, patients are unable to detect approximately 60 percent of hypoglycemic events, and have difficulty assessing glucose fluctuations while they sleep.

Medtronic Diabetes currently markets the CGMS® System Gold and the recently FDA approved MiniMed Paradigm® REAL-Time Insulin Pump and Continuous Glucose Monitoring System – the world’s first insulin pump with REAL-Time continuous glucose monitoring. The MiniMed Paradigm REAL-Time System has all of the benefits of CGM plus the added value of precise insulin delivery through the use of insulin pump therapy. Medtronic Diabetes continues to lead the industry in developing new medical device technologies to improve overall diabetes management.

Diabetes Statistics
According to the American Diabetes Association, almost 21 million Americans (seven percent of the population) have the disease. Diabetes affects children and adults, costing the United States more than $132 billion in direct and indirect costs.
