St. Jude Medical, Inc. (NYSE:STJ) today announced U.S. Food and Drug Administration (FDA) approval of its new tachycardia software for the Merlin™ Patient Care System, a state-of-the-art computer used to program and interrogate cardiac rhythm management devices like pacemakers and implantable cardioverter defibrillators (ICDs).

This software upgrade, which will be launched over the coming weeks, extends the benefits of the previously released Merlin graphical user interface to both St. Jude Medical pacemaker and ICD products. The system, which supports current and previous generation devices, is one of more than 20 new cardiac rhythm management products being introduced by St. Jude Medical this year.

The Merlin Patient Care System, which received FDA approval in April 2006, is a programmer designed to help physicians more efficiently conduct tests and analyze therapeutic and diagnostic data. This powerful, portable computer helps physicians retrieve and analyze patient information during routine pacemaker and ICD follow-up visits, providing quality patient care. With the Merlin Patient Care System, physicians can quickly and easily make changes to device therapy using an LCD touch-screen.

The system’s streamlined workflow is designed to increase productivity for physicians and clinic staff. With the Merlin Patient Care System, patients can receive the same high standard of care during follow-up visits that take significantly less time.

“The Merlin system has truly raised the bar in helping me provide better care to my patients,” said Joseph Dell’Orfano, M.D., Saint Francis Hospital and Medical Center, Hartford, Conn. “This new ICD software allows me to increase the efficiency of my clinic by reducing patient follow-up time and simplifying training requirements for my staff.”

The Merlin Patient Care System was designed with the help of clinicians to better manage patients with pacemakers and ICDs. The system represents an evolution in programmer technology and includes easy-to-use graphical screens so clinicians can more efficiently assess device function and care for their patients. With the new software, this system provides physicians with a complete solution to St. Jude Medical pacemaker and ICD follow-up visits.

“Physicians have responded enthusiastically to the Merlin Patient Care System,” said Michael J. Coyle, president of St. Jude Medical’s Cardiac Rhythm Management Division. “With the new ICD interface, we are demonstrating our commitment to making follow-ups more efficient for both our bradycardia and tachycardia customers, while focusing on patients.”
