Medtronic introduces cardiopulmonary bypass system

21 April 2006

Minneapolis, USA. Medtronic, Inc. (NYSE:MDT) has received U.S. Food and Drug Administration clearance for its Medtronic Performer Cardiopulmonary Bypass System (CPB), an integrated, compact console capable of providing total support of the circulatory system during a variety of cardiac surgical procedures.

"The Performer integrates all of the components that Medtronic has to offer with an innovative pumping system in a small footprint and features that are controlled on a touch-screen," said Brian McCloskey, chief of clinical perfusion, Foothills General Hospital Calgary, Alberta. "Together with the Medtronic Resting Heart System (RHS), it is an excellent package providing an effective way to run an advanced mini-circuit on a small pump base. It takes up significantly less OR space and helps with coordination of all of the monitoring devices I work with."

Michael Harostock, M.D., chief of cardiothoracic surgery at Wilkes-Barre General Hospital in Wilkes-Barre, Pa., reports 250 patients at the institution have undergone heart surgery using the Medtronic Resting Heart System.

"Compared with a similar group, the blood utilization decreased 27% and indicated a decrease in the overall transfusion rate by 37% in people who came to the operating room with a hematocrit of less than 35%," said Harostock. "Now, thanks to this new machine, our patients have access to the best heart and lung technology available. The major benefit to our bypass patient is that it results in a safer and more healthful surgery."

"Medtronic is committed to developing medical advances that meet the needs of the patient and his or her surgical team," said Oern Stuge, president, Medtronic Cardiac Surgery. "This industry-leading extracorporeal support system facilitates those procedures and is upgradeable to accommodate new procedures into the future."

The new system, which has evolved from proven extracorporeal support technologies, incorporates the Medtronic Bio-Pump Plus in the arterial position — which plays the role of the heart when the blood must be routed outside the body — as well as four peristaltic-type roller pumps for non-arterial fluid delivery and retrieval functions. System controls support individual pump function and a central information display with colour touch-screen incorporates graphic menus and buttons for user-selectable options. The system monitors all functions pertinent to patient physiology during use and its servo safety technologies provide visual and audible signals and alarms as needed. Height is electrically adjustable, allowing the instrument to be placed closer to the patient.

The Performer CPB also incorporates data management functions to capture, display, store and transmit all key instrument-related perfusion parameters throughout an entire operation. Data can be transmitted from the system to an external Microsoft Office Excel-based macro program for report and graph generation and case records.
