Feature & Benefits


Embosphere® Microspheres temporarily compress to facilitate smooth microcatheter passage (A).Once through the microcatheter, Embosphere® Microspheres return to their original spherical shape and stated diameter (B) for predictable, targeted delivery.2






Embosphere® Microspheres show a direct correlation between the level of arterial occlusion and the size of the microspheres used, allowing for consistent, targeted occlusion.3,4







Merit Medical’s new Embosphere PRO™ Prostatic Artery Embolization Kit combines the power and predictability of Embosphere® Microspheres with basic preparation and delivery tools for added convenience.

Each Kit Includes

(1) prefilled syringe of Embosphere® Microspheres, 300-500μm or 100-300μm
(1) 10 mL Medallion® Syringe
(1) 3 mL Medallion® Syringe
(2) 1 mL Medallion® Syringes
(1) 3-way Medallion® Stopcock, 1050 psi


Embosphere® Microspheres are the most clinically studied and clinically utilized spherical embolic, having been proven:

During more than 20 years of clinical use
In more than 200 clinical articles, with more than 35 PAE-related1

PAE Clinical Summary with Embosphere® Microspheres1

A composite database of 286 patients who underwent PAE using Embosphere® Microspheres for treatment of symptomatic benign prostatic hyperplasia (BPH) was analyzed to evaluate clinical outcomes. All patients were suffering from lower urinary tract symptoms (LUTS) due to BPH with International Prostate Symptom Scores (IPSS) of moderate to severe.

Post embolization, 97% of patients reported a decrease in their IPSS by at least 3 points, and 90% of patients dropped at least 1 symptom category, from severe to moderate or moderate to mild.

Most patients also experienced improvement in their Quality of Life score and a substantial decrease in prostate volume.
