Features & Benefits
PREDICTABLE
Embosphere Microspheres temporarily compress up to 33% for smooth microcatheter passage. Once through the microcatheter, they return to their original spherical shape and stated diameter for predictable, reliable delivery.1
TARGETED
Embosphere Microspheres show a direct correlation between the level of arterial occlusion and the size of the particles used, allowing for consistent and reliable targeted occlusion.2,3
ESTABLISHED
Embosphere Microspheres have been proven:
• In more than 130 pivotal clinical articles3
• In over 8,000 procedures reported in clinical studies
• In over 25 years of clinical experience
• In more than 800,000 patients worldwide
NON-AGGREGATING PROPERTIES
The hydrophilic surface and spherical shape of Embosphere Microspheres prevent aggregation in the catheter lumen and vasculature.1
PREDICTABLE & TARGETED DELIVERY
Embosphere Microspheres’ rebound capabilities help maintain a spherical shape for predictable distribution & occlusion. In contrast, Embozene® Microspheres show a higher in vivo deformation, resulting in unpredictable occlusion.4
REBOUND CAPABILITY
Embosphere Microspheres’ elastic properties allow temporary compression of up to 33% to facilitate smooth microcatheter passage (left image).1 Once through the microcatheter, Embosphere Microspheres return to their original spherical shape and stated diameter (right image) for predictable, targeted delivery.1
DURABLE OCCLUSION
Embosphere Microspheres are biocompatible and nonresorbable with cell adhesion properties that enable complete and durable mechanical occlusion.1
PERCENTAGE OF PATIENTS WITH COMPLETE INFARCTION RATES OF OVERALL UTERINE FIBROID TUMOR BURDEN
Embosphere Microspheres offer high total fibroid infarction rates of up to 92.3%, compared to infarction rates for competitive devices of up to 70.0%.5,6
UFE rates are defined differently, results are from different studies and may vary in head-to-head comparison. Graphics are for illustration purposes only.
