About BioSphere Medical, Inc.

BioSphere Medical, Inc., based in Rockland, Massachusetts, is a medical device company focused on applying its proprietary microsphere technology to medical applications using embolotherapy techniques. The company’s core technologies, patented bio-engineered polymers and manufacturing methods, are used to produce miniature spherical beads with uniquely beneficial properties for a variety of medical applications. The company’s principal focus is the treatment of symptomatic uterine fibroids using a procedure called uterine fibroid embolization, or UFE. The company’s products have already begun to gain wide acceptance in this rapidly emerging procedure as well as in a number of other new and established medical treatments. The company’s strategy is two fold. First, it is seeking to grow the embolotherapy business worldwide, specifically the UFE procedure, by increasing awareness of availability of this procedure. Second, it is seeking to maintain its current technology leadership by introducing new products and product improvements, both through internally developed and externally acquired technologies, that improve and broaden the use of embolotherapy techniques.

BioSphere Medical has received clearance in many countries, including the United States, Canada, Australia and the European Community, which allow the company to sell its products for use in general embolization procedures, including uterine fibroid embolization.
