Embolics

Controlled, Targeted Embolization

BioSphere Medical's microspheres are precisely calibrated, spherical, hydrophilic, micro-porous beads made of an acrylic co-polymer (trisacryl) which is then cross-linked with gelatin. This proprietary and patented design allows a more complete and targeted occlusion of the blood vessels feeding a hypervascularized tumor or arteriovenous malformation. Furthermore, the hydrophilic surface and spherical shape prevent aggregation within the catheter lumen and in the vasculature, promoting ease and accuracy of delivery. Finally, the elastic properties of the microspheres also allow the temporary deformation of the sphere, which facilitates the passage through small delivery systems.
