Boston Scientific Corp. sent warning notices of the potential for embolisms arising from use of its Spaceoar and Spaceoar Vue systems because of “inadvertent placement of Spaceoar gel into a blood vessel and subsequent migration of the hydrogel outside of the pelvis.”

Boston Scientific Corp. reported that it has initiated the nationwide U.S. launch of Spaceoar Vue Hydrogel, a radiopaque version of Spaceoar Hydrogel that enables the use of computerized tomography scans instead of requiring magnetic resonance imaging (MRI) for patients undergoing radiation for prostate cancer.
