Embosphere Microsphere


Embosphere Microsphere is an embolic material used during UFE. Each tiny microsphere, or round particle, is about the size of a grain of sand and is made of tris-acryl gelatin, a material safe for use in the human body.

During the UFE procedure, the microspheres are delivered through a slim tube called a catheter into blood vessels that supply fibroids with blood. These particles reduce blood flow to the fibroids, causing them to shrink and symptoms to improve.


Embosphere has been trusted for more than 20 years for use in embolization procedures that treat a variety of medical conditions, including fibroids.

Today, it is the most widely used round embolic material, applied to over 350,000 procedures worldwide.


When treating fibroids with UFE, complete infarction (obstruction of fibroid blood supply) leads to better long-term clinical outcomes, including a higher rate of symptom control and a lower rate of additional fibroid treatment compared with incomplete infarction of fibroid tissue.2

While other microspheres are shown to get mixed results, 92.3% of patients treated with Embosphere experienced 100% infarction of their entire uterine fibroid tumor burden.3

Requesting Embosphere for UFE

Using Embosphere for UFE has been linked to high levels of durable symptom control, improved health-related quality of life, patient satisfaction, and is considered the gold standard for embolic material.4  Almost every interventional radiologist keeps Embosphere in stock and will use it to perform UFE upon request.
