I-Flow Launches Gertie Marx(R) Tray and EpiStar(R) System at 25th

Anniversary American Society of Regional Anesthesia Annual Meeting

I-Flow Corp. (Nasdaq:IFLO) announced the availability of two leading products in pain management -- the Gertie Marx(R) Spinal Tray and the EpiStar(R) Combined Spinal and Epidural System.

The announcement was made at the 25th Anniversary American Society of Regional Anesthesia (ASRA) Annual Meeting held in Orlando from March 30 through April 2, 2000.

"Both the Gertie Marx Spinal Tray and the EpiStar System are examples of the types of leading products we are bringing to the fields of regional anesthesia and pain management," said Donald M. Earhart, president and chief executive officer of I-Flow. "Thanks to products like these, spinal blocks are becoming safer and easier to perform than ever before."

The Gertie Marx Spinal Tray -- designed to "hit the mark every time with pin-point accuracy" for spinal block procedures -- is uniquely designed to allow precision drug delivery with increased safety and reduced incidents of spinal headaches for patients.

The atraumatic Gertie Marx spinal needle's pencil-point design has a patented eyelet placement that is closer to the point, increasing safety. The needle can be specified in any custom spinal tray through Spinal Specialities, an I-Flow company.

The EpiStar Combined Spinal and Epidural System is designed to allow catheter introduction and verification before the spinal injection. This allows for a safer procedure because the catheter position can be verified -- through a test dose -- before the spinal injection is made.

"This is a vast improvement over other methods that require the spinal injection to be made first," said Roger Massengale, I-Flow's vice president of marketing and business development. "If the spinal injection is made first, it becomes very difficult to verify the catheter position because the effects of the spinal drug are almost immediate. The EpiStar eliminates this problem by combining an introducer needle, catheter and spinal needle into a single system."

I-Flow is a Lake Forest, Calif.-based medical device company with a comprehensive line of pain management products including the PainBuster(R), ON-Q(TM), C-Bloc(TM) Continuous Nerve Block System and Paragon(R) products.

I-Flow is redefining the standard of care by providing life enhancing, cost effective solutions for pain management and infusion therapy. The company develops, manufactures and markets ambulatory infusion systems that are cost effective and easy for patients to use.
