FDA Clears BioSphere Medical's Next Generation EmboCath(R) Plus Infusion Microcatheter.

ROCKLAND, Mass. -- BioSphere Medical, Inc. (NASDAQ: BSMD), a medical device company that pioneered the use of bioengineered microspheres to treat uterine fibroids, hypervascularized tumors and vascular malformations by a procedure called embolization, today announced that the U.S. Food and Drug Administration has cleared for marketing in the United States BioSphere Medical's EmboCath(R) Plus Infusion Microcatheter. EmboCath Plus is expected to begin shipping in the United States in September 2006.

Richard Faleschini, BioSphere Medical's president and chief executive officer, said, "The approval of EmboCath Plus further expands BioSphere Medical's portfolio of proprietary embolization system solutions. It is designed to provide exceptional performance in the delivery of embolic, diagnostic, and therapeutic agents into the peripheral vascular system for interventional procedures such as uterine fibroid embolization and the embolization of hypervascularized tumors. EmboCath Plus was designed for use with BioSphere Medical's existing and planned new products, including: our Sequitor(TM) Steerable Guidewire, which received FDA approval in June 2006 and which will begin shipping this month, our currently marketed Embosphere(R) Microspheres, EmboGold(R) Microspheres, and our QuadraSphere(TM) Microspheres product candidate, for which we have submitted a 510(k) premarket notification to the FDA."

EmboCath Plus is designed to possess performance characteristics that include:

--Controlled delivery, featuring the largest internal lumen diameter in its class - 0.028"- which provides a 10% greater flow rate than competitive products

--A flexible, kink-resistant, durable design that offers optimal balance for agile tracking

--A clear, chemo-compatible hub designed for smooth, fluent injection of microspheres

--Enhanced fluoroscopic ability via an extra-bright tip

Gary Saxton, BioSphere Medical's executive vice president and chief operating officer, commented, "EmboCath Plus is the second FDA approval received by BioSphere Medical this year. I believe that this approval demonstrates our ability to effectively advance new product candidates rapidly through development and engineering, and regulatory approval. EmboCath Plus and our recently approved Sequitor Steerable Guidewire build upon the advantages of our first generation embolic delivery system by providing a new fully integrated system for optimal embolic performance."
