Please describe the particles used to block the arteries in a Uterine Fibroid Embolization (UFE)

The particles that we use for the embolization are what I like to describe as little small gelatin balls. They were actually first used in chromatography and they actually are like gelatin, it’s a material that’s really very uniform and we go in the range of sizes, 500-700 microns is the ones I use most commonly.

They float in the liquid, the contrast or the saline that we put in, and we can put as many as we want or as little as we want. They are inert so they don’t do anything, they’re not radioactive. They’re just like tapioca pudding, they’re just little gelatin balls, they go there and they just block the artery.
