Possis Receives FDA Clearance for GuardDOG(R) Occlusion System

New Device Allows Physicians to Quickly and Effectively Manage Blood Flow During Peripheral Interventions

MINNEAPOLIS--(HSMN NewsFeed)--Aug. 22, 2006--Possis Medical, Inc. (NASDAQ:POSS ), today announced that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for its GuardDOG® Occlusion System for use during the treatment of peripheral vascular disease. The GuardDOG System enables physicians to quickly and effectively manage local blood flow while employing interventional techniques and devices to treat vascular disease.

"We are excited about the potential of the GuardDOG System," said Robert G. Dutcher, CEO of Possis Medical. "Peripheral vascular disease is a potentially limb and life threatening condition, and the GuardDOG Occlusion System provides a new option for controlling local blood flow and facilitating infusion of therapeutic or diagnostic fluids, as well as delivery of interventional devices."

The GuardDOG Occlusion System is the first guidewire-based occlusion device designed and marketed with the specific challenges of the peripheral vasculature in mind. It features a 0.035" diameter guidewire, preferred for peripheral interventions, and a soft, compliant, CO2-filled balloon providing quick inflation and deflation. Designed to facilitate delivery of over-the-wire interventional tools, the GuardDOG System can be delivered through 0.038" diagnostic catheters to the treatment site. The GuardDOG System can be inflated, deflated and positioned up to three times during a single procedure, improving efficiencies in both routine and complicated procedures. These GuardDOG System features enable physicians to manage blood flow and achieve desired occlusion in peripheral vessels 3-6mm in size.

Said Dutcher, "Effective blood flow management is important in minimizing interventional treatment risks. Based on physician feedback, we believe the GuardDOG device will also enhance the effectiveness of our AngioJet® Rheolytic(TM) Thrombectomy System and PowerPulse(TM) lytic drug delivery therapy in the removal of tough peripheral thrombus."

Possis is currently completing necessary production requirements in preparation for market evaluations at select medical sites to support full U.S. market release of the GuardDOG System by the end of the calendar year. Anticipated revenue from the GuardDOG System is reflected in the Company's current guidance for fiscal 2007.

In addition to the 0.0035" GuardDOG device, Possis is also developing a 0.014" version of the device. The Company expects 510(k) clearance for the 0.014" version later in fiscal 2007.
