Great progress has been made in every facet of our business, with contributions coming from each business function and each major geographic sector. We have at present nearly all the product approvals we've sought, and with the other elements of our marketing mix now in place, we believe that we are well positioned for continued growth in 2007."

Significant highlights, activities and developments in the fourth quarter of 2006 and subsequent weeks include:

* Full-year 2006 worldwide sales of embolics used for uterine fibroid embolization were $16.19 million, an increase of 28% compared to full-year 2005 worldwide uterine fibroid embolic sales, with full-year 2006 United States uterine fibroid embolic sales of $13.67 million, an increase of 32% compared to full-year 2005 United States uterine fibroid embolic sales.

* Full-year 2006 worldwide sales of embolics primarily used in the treatment of liver tumors were $3.32 million, an increase of 23% compared to full-year 2005 worldwide sales of liver-related embolic sales, with full-year 2006 United States liver-related embolic sales of $2.27 million, an increase of 26% compared to full-year 2005 United States liver-related embolic sales.

* Fourth quarter 2006 worldwide sales of embolics used for uterine fibroid embolization were $4.39 million, an increase of 20% compared to the same period last year, with United States uterine fibroid embolic sales of $3.71 million, an increase of 22% compared to the fourth quarter of 2005.

* Worldwide sales in the fourth quarter of 2006 were $0.96 million for embolics used in the treatment of liver tumors, an increase of 32% compared to the same period last year.

* The Company received U.S. Food and Drug Administration marketing clearance for QuadraSphere(TM) Microspheres, the Company's third FDA approval in 2006.

* In the November 7, 2006 Wall Street Journal, a feature highlighted the results of a survey conducted by BioSphere in partnership with the not-for-profit The National Women's Health Resource Center, or NWHRC. One finding from the research was that more than 40% of the women surveyed reported they discussed UFE with their medical professional, and of those, approximately 35% went on to have UFE as the treatment for their symptomatic fibroid condition. We believe the results of this survey are encouraging because they suggest that women and gynecologists are better informed today about UFE than they were two years ago, and that their decisions are influenced by credible information.

* A live-case and scientific presentation featuring BioSphere Medical's QuadraSphere Microspheres are scheduled at the 2007 International Symposium on Endovascular Therapy.

* The January 2007 issue of the New England Journal of Medicine includes the results of the following study: Uterine-Artery Embolization versus Surgery for Symptomatic Uterine Fibroids. This randomized study included 157 women and was conducted at 27 hospitals in the United Kingdom. Patients were randomly assigned to undergo either uterine artery embolization or surgery, with 106 patients undergoing embolization and 51 undergoing surgery (43 hysterectomies and 8 myomectomies). This study showed that uterine fibroid embolization had an equivalent quality-of-life benefit when compared to traditional surgical options, and highlighted the advantages of embolization, including a significant reduction in the length of hospital stay and 24-hour pain level, and a more rapid return to usual activities.

About BioSphere Medical, Inc.

BioSphere Medical, Inc., a medical device company based in Rockland, Massachusetts, has pioneered and is commercializing minimally invasive diagnostic and therapeutic products based on its proprietary bioengineered microsphere technology. The Company's core technologies, patented bioengineered polymers and manufacturing methods, are used to produce microscopic spherical materials with unique beneficial properties, which the Company believes have the potential for use in a variety of medical applications. BioSphere's principal focus is the application of its Embosphere[R] Microspheres product for the treatment of symptomatic uterine fibroids using a procedure called uterine fibroid embolization, or UFE. The Company's products have continued to gain acceptance in this emerging procedure as well as in a number of other new and established medical treatments.

BioSphere Medical has received clearance in many countries, including the United States, Canada, Australia, the European Community, and Latin America, which allows the Company to sell its products for use in general embolization procedures, including uterine fibroid embolization. The terms uterine fibroid embolization (UFE) and uterine artery embolization (UAE) are generally used interchangeably in the literature. The most common side effect of UFE is "post-embolization syndrome," a collection of symptoms including abdominal pain, discomfort, low-grade fever and nausea. UFE is currently contraindicated for women who are, or who intend to become, pregnant, because the effects of UFE on the ability of a woman to conceive, and to carry a fetus to term, have not been determined.
