I-Flow Corporation Announces That Results of ON-Q Colorectal Study Will Be Presented at Infectious Diseases Conference in September

LAKE FOREST, Calif.--(BUSINESS WIRE)--Aug 29, 2007 - I-Flow Corporation (NASDAQ:IFLO) announced today that results of its ON-Q prospective human study in colorectal surgery will be presented on Tuesday, September 18th at the world-renowned 47th Interscience Conference on Antimicrobial Agents & Chemotherapy (ICAAC) in Chicago, Illinois.

The study was designed to explore the potential of ON-Q to reduce surgical site infections and to therefore expand ON-Q's clinical benefits beyond pain relief into the area of surgical site care. Today ON-Q is used to treat post-surgical pain in place of narcotics - yesterday's standard of care.

Abstracts that are presented at ICAAC, including the ON-Q study findings, are peer-reviewed and selected by the Society's esteemed faculty that is comprised of internationally renowned scientists. The ON-Q presentation was submitted as a "Late-Breaker" entry, a highly selective category of which only one of four entries is deemed notable enough to be presented. ICAAC attracts more than 12,000 attendees -- physicians, researchers and other healthcare professionals from around the world - who come together to foster solutions to the problem of infectious diseases.

The inherent risks and exceptionally high costs of caring for patients with surgical site infections has created a significant interest recently in the medical and investment communities around finding solutions to the problem. According to the Centers for Disease Control and Prevention's (CDC's) National Nosocomial Infections Surveillance (NNIS) system, surgical site infections often increase patient length of stay in the hospital by an average of seven or more days and cost the healthcare system hundreds of millions of dollars each year.

About ON-Q

ON-Q is now labeled to significantly reduce pain better than narcotics and to significantly reduce narcotics intake after surgery. ON-Q therapy was recently upheld as a best practice for post-surgical pain relief and its widespread use was encouraged in an independent study published in the prestigious Journal of American College of Surgeons. The large-scale pain relief meta-analysis included 2,141 patients across a wide range of surgical procedures.

ON-Q is a simple yet elegant device that consists of a small balloon pump that holds a local anesthetic (a pain-numbing medicine) and delivers it automatically through a specially designed catheter to provide even distribution of local anesthetic over a wider area, as compared to other catheters, because of its patented wicking capabilities.

Currently, more than 55 studies on the use of ON-Q have been completed and published or presented and more are underway to demonstrate the benefits of ON-Q in additional areas such as reduced infection risk, combination therapies (e.g., local anesthetic and antibiotic mixtures, a combination of a local anesthetic and an anti-inflammatory), pediatrics and chronic pain. In addition, effective January 1, 2007, Medicare recognized the ON-Q therapy as a payable covered benefit and therefore medically necessary. To learn more about the benefits of ON-Q visit
