BioSphere Medical Announces ACOG Practice Bulletin Recommendation of Uterine Artery Embolization As Alternative to Hysterectomy

BioSphere Medical, Inc. (NASDAQ:BSMD)("BioSphere") - a medical device company that has pioneered the use of bioengineered microspheres to treat uterine fibroids, hypervascularized tumors and vascular malformations by a minimally invasive, image-guided medical procedure called embolotherapy - today announced that in its August Practice Bulletin, the American College of Obstetricians and Gynecologists (ACOG) recommended uterine artery embolization (UAE) (also known as UFE) as an alternative to hysterectomy in the management of leiomyomas (fibroids). The bulletin cites the availability of Level A research, which is based on "good and consistent scientific evidence" that shows that UAE "is a safe and effective option for appropriately selected women who wish to retain their uteri." The recommendation is also based on both long- and short-term treatment outcomes.

"We are pleased UFE has obtained this important recognition, and believe it is a significant step in the ongoing development of the market for this minimally invasive, uterus-sparing alternative to hysterectomy," commented Richard J. Faleschini, president and CEO of BioSphere Medical. Mr. Faleschini continued, "Gynecologists are one of the key providers in women's health. We believe the new guidelines in this Practice Bulletin should result in more gynecologists discussing UFE as a mainstream treatment option with their patients and forging collaborative relationships with interventional radiologists to optimize the quality of care offered to women with fibroids."
