Merit Medical's Embosphere® Microspheres, EmboGold® Microspheres, QuadraSphere® Microspheres, and HepaSphere™ Microspheres are calibrated, spherical, hydrophilic spheres. These proprietary designs allow more complete and targeted occlusion of the blood vessels feeding a hypervascular tumor or arteriovenous malformation. The hydrophilic surface and spherical shape of the spheres prevent aggregation within microcatheter lumens* and in the vasculature, promoting ease and accuracy of delivery.
