St. Jude Medical Announces FDA Approval, FDA Clearance and European CE Mark of New Electrophysiology Products; Heart Rhythm Society Meeting to Showcase Strength and Breadth of Product Offering.

ST. PAUL, Minn. -- St. Jude Medical, Inc. (NYSE:STJ) today announced U.S. Food and Drug Administration (FDA) approval of its Safire(TM) Ablation Catheter, and FDA clearance and European CE Mark for its Inquiry(TM) Optima(TM) PLUS Steerable Diagnostic Catheter.

St. Jude Medical made the announcement at the Heart Rhythm Society's 27th Annual Scientific Sessions in Boston, where these products will be featured for the first time.

The Safire catheter, featuring the new ComfortGrip(TM) handle, can be easily integrated into any existing radiofrequency (RF) generators, and gives physicians improved comfort and control during electrophysiology (EP) procedures. "The catheter exceeded the performance expectation I had," said Robert Schweikert, M.D., of the Cleveland Clinic. "The catheter did a great job reaching its position and then remaining stable once it was there. We used the Safire ablation catheter on a somewhat difficult case and at a challenging position, but the catheter performed quite well and we achieved an excellent outcome."

The Optima PLUS helps physicians map the heart's atria with a 24-electrode catheter that allows physicians to collect more diagnostic data, more quickly when used with St. Jude Medical's newly approved EnSite(R) System Version 6 software. Using this 3-D imaging technology, the physician will "see" the catheter's position inside the heart. Four electrodes on the 180-degree deflectable shaft display the loop and shaft planes of motion simultaneously in this advanced mapping system.

In addition to Safire and Optima PLUS, St. Jude Medical will showcase a portfolio of catheter-based and surgical ablation products at Heart Rhythm 2006. These new technologies include:

A[micro]   --  The EnSite System Version 6 software, which received FDA
        clearance earlier in May. The EnSite System is designed to
        provide highly detailed, three-dimensional (3-D) cardiac
        models at the time of an EP procedure. Physicians create the
        3-D model in small sections that join together automatically,
        resulting in a cardiac model that shows the openings, ridges
        and curves in the heart. The models are then used by
        physicians to collect information about the heart's electrical
        activity and assist them in diagnosing and treating many
        arrhythmias, including atrial fibrillation.

A[micro]       EnSite System users at hospitals worldwide will also now have
        the option to connect to a technical support team that can
        resolve issues in real time via a secure, broadband Internet
        connection with EnSite Connect(TM) Remote Support. This is the
        industry's first remote technical support for a cardiac
        mapping system.

A[micro]   --  The Agilis(TM) NxT Steerable Introducer, which is available in
        Europe, reduces the puncture size required when physicians
        access the left side of the heart, yet maintains a larger
        inside diameter to help physicians deliver a wide variety of
        catheters.

"The Heart Rhythm Society meeting is an important opportunity for us to collaborate with clinicians from around the world on the latest techniques for treatment of complex arrhythmias such as atrial fibrillation," said Jane J. Song, president of St. Jude Medical's Atrial Fibrillation Division. "St. Jude Medical is dedicated to leading initiatives to help bring about a cure for an increasing number of patients with Atrial Fibrillation, including developing new technologies, procedures and clinical studies."

At Heart Rhythm 2006, St. Jude Medical will feature in-booth presentations by physicians who will relate their experiences with the EnSite System, Agilis Steerable Introducer and building a successful AF treatment program. St. Jude Medical also will sponsor two symposia:

A[micro]   --  "Raising the Bar by Hybrid Substrate Modification," moderated
        by electrophysiologists Andrea Natale, M.D., and David J.
        Wilber, M.D., on Wednesday, May 17.

A[micro]   --  "Frontiers in the Treatment of Atrial Fibrillation," hosted by
        Douglas L. Packer, M.D., and Shih-Ann Chen, M.D., on Thursday,
        May 18.
