FDA Clears BioSphere Medical, Inc.'s Next Generation Sequitor(TM) Steerable Guidewire

ROCKLAND, Mass.--(BUSINESS WIRE)--June 9, 2006--BioSphere Medical, Inc. (NASDAQ: BSMD - News), 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 (“FDA”) has cleared the BioSphere Medical Sequitor(TM) Steerable Guidewire (“Sequitor”) Premarket Notification (510K) that allows Sequitor to be marketed in the United States. Sequitor is expected to begin shipping in the United States in July 2006.

BioSphere’s internally developed Sequitor guidewire is the newest addition to the company’s line of embolic delivery products. Designed specifically to address the needs of interventionalists, Sequitor facilitates the placement of catheters within the peripheral vasculature for various interventional procedures, including both uterine fibroid embolization and embolization of hypervascularized tumors, such as liver tumors.

Following the completion of certain documentation requirements to conform to European regulations, BioSphere also expects to complete the CE marking of Sequitor and to launch it in Europe in July 2006. CE marking denotes conformity with European Medical Device Directive (EC Council Directives 93/42/EEC) and allows for marketing in European Union countries.

Richard Faleschini, BioSphere Medical’s president and chief executive officer, said, “The introduction of Sequitor is a next step toward our goal to optimize BioSphere delivery systems products for peripheral embolization procedures. With Sequitor’s trackability, torque response, distal steerability, visibility under fluoroscopy, and innovative hydrophilic coating, we believe we have developed a best-in-class guidewire that will clearly establish BioSphere’s technical leadership in delivery system technology. In addition, while Sequitor can be used with our existing products, including our EmboCath® infusion catheter, it has also been designed to be used with our new EmboCath® Plus infusion catheter, which is under development, and whose 510K we expect to submit to the FDA during the third quarter of 2006.”

Mr. Faleschini noted that Sequitor possesses:

A durable atraumatic polymer tip that reduces the risk of vascular spasm but retains its shape for selective vessel access; A highly visible distal segment, comprised of a radiopaque coil and polymer jacket, which provides visibility under live imaging; A specially tempered wire core designed to transmit one-to-one torque response without kinking; and PASSTHRU(TM) lubricious, hydrophilic coating that facilitates wire trackability.
