Embosphere Microspheres continue to be the embolic of choice for predictable clinical results, ease of use and long-term symptom control. Of the microspheres tested, Embosphere is the only microsphere to consistently demonstrate high infarction rates of all fibroids, which provides long-term symptom control and a significantly lower rate of reintervention.1 With Embosphere, 92.3% of patients that underwent uterine fibroid embolization (UFE) experienced complete (100%) infarction of their entire fibroid burden.2 Competing microspheres don’t compare. In addition to Embosphere, the leading spherical embolic for UFE, Merit Medical offers interventional radiologists a wide array of tools to support their UFE procedures every step of the way, whether your access is radial or femoral.
