The only spherical embolic agent comprised of PVA hydrogel cross-linked with acrylic polymerHow does Bead Block ® compare?What does this mean?2Bead Block ®PVA hydrogel cross-linked with acrylic polymerEmbosphere ®Acrylic polymer structure (Trisacryl ® )Contour SE Macroporous PVA 1Embozene Polyphosphazene-coated polymethylmethacrylateRigidity and fragmentation• Bead Block ® is significantly less rigid than Embosphere ® . 3• An in-vivo animal study by Bilbao et al, 2 published in JVIR in 2008, demonstratedthat:– Bead Block remained round or slightly oval and showed no fragmentationat 48 hours after embolization. 2– Embosphere had a large number of particles that showed a fragmentedappearance at 48 hours after embolization. 2• Trisacryl ® gelatin microspheres (Embosphere) have a high rigidity and deformslightly under a sustained compression since they have a high elasticity. 4• Polyphosphazene-coated polymethylmethacrylate microspheres (Embozene )are soft and deform considerably under sustained compression and are more viscousthan Bead Block and Embosphere. 4
