- Product Details
Indications for Use
Embolic Microspheres are intended to be used for the embolization of arteriovenous malformations (AVMs) and hypervascular tumors, including uterine fibroids.
Device Description
Embolic Microspheres are compressible hydrogel microspheres with a regular shape, smooth surface, and calibrated size, which are formed as a result of chemical modification on polyvinyl alcohol (PVA) materials.
Embolic Microspheres consist of a macromer derived from polyvinyl alcohol (PVA), and are hydrophilic, non-resorbable, and are available in a range of sizes.
The preservation solution is 0.9% sodium chloride solution. The water content of fully polymerized microsphere is 91% ~ 94%. Microspheres can tolerate compression of 30%. Embolic Microspheres are supplied sterile and packaged in sealed glass vials.
By blocking the blood supply to the target area, the tumor or malformation is starved of nutrients and shrinks in size.
Embolic Microspheres can be delivered through typical microcatheters in the 1.7 - 4 Fr range. At the time of use, Embolic Microspheres are mixed with a nonionic contrast agent to form a suspension solution. Embolic Microspheres are intended for single use and are supplied sterile and non-pyrogenic.
Among the various size ranges of Embolic Microspheres, the size ranges that can be used for uterine fibroid embolization are 500-700μm, 700-900μm and 900-1200μm.
