AngioDynamics Announces Availability of AngioFlow™ Thermal Dilution Catheter and AngioFlow™ Meter in the U.S.Queensbury, NY, April 20, 2004 – ANGIODYNAMICS, INC., a wholly owned subsidiary of E-Z-EM, Inc., (AMEX: EZM) today announced the introduction of the AngioFlow™ Thermal Dilution Catheter and AngioFlow Meter in the United States, collectively known as the AngioFlow System. The AngioFlow System is a catheter-based flow meter the Company believes will be the first device to measure blood flow in hemodialysis access sites during an access site clearing procedure.

Maintaining the patency of a vascular access graft or fistula is critical to the survival of patients with chronic renal failure. Several studies have determined that a blood flow less than 600ml/min is predictive of a developing stenosis within a graft or fistula. If left untreated, the graft or fistula will occlude, and the patient will be unable to undergo hemodialysis treatment. Multiple endovascular and surgical interventions are frequently required to maintain patency of a vascular access. The AngioFlow System provides accurate and immediate blood flow measurements during these interventions.

Dr. Tom Vesely, an Associate Professor of Radiology, Surgery, and Medicine at the Washington University School of Medicine in Saint Louis, has extensive clinical experience with the AngioFlow system. Commenting on this technology, Dr. Vesely stated, “The AngioFlow system provides valuable and immediate information that is useful for the detection of inconspicuous lesions, optimizing our reparative procedures, and helping to restore full function to the patient's vascular access.”

Commenting for AngioDynamics, Don Geer, Director of Marketing for Vascular Access Products, said, “Due to the aging of the population and other factors, the long-term care of patients with chronic renal failure is a growing medical problem. The AngioFlow System helps physicians treat these patients by providing important data on blood flow through the vascular access graft site, and as such represents an important addition to AngioDynamics' dialysis product line. We are pleased to able to bring this important product to physicians and their patients.”
