Uterine Fibroid Embolization

Prostatic Artery Embolization


Embosphere® Microspheres

Embosphere Microspheres are the most clinically studied and clinically proven round embolic, providing you consistent and predictable results for effective embolization. Elastic properties allow temporary compression of up to 33%,1 facilitating smooth microcatheter passage. Microspheres return to stated diameter after delivery, contributing to durable and targeted results.

EmboGold® Microspheres

EmboGold Microspheres are colored to enhance visualization during handling while still offering you the controlled, targeted embolization characteristics of Embosphere Microspheres. EmboGold Microspheres are biocompatible, hydrophilic, non-resorbable, and precisely calibrated. The product is provided in a pre-filled syringe for easy handling, superior procedural efficiency, and enhanced safety for your procedures.

Bearing nsPVA® Embolization Particles

Bearing nsPVA Embolization Particles are irregularly shaped, biocompatible, hydrophilic, nonresorbable particles produced from polyvinyl alcohol. To support your procedures, these particles are intended to provide vascular occlusion or reduction of blood flow within target vessels upon selective placement through a variety of catheters. Size distribution of Bearing nsPVA is more tightly calibrated than the leading competitor.5

Merit Pursue™ Microcatheters

Merit Pursue Microcatheters are small distal French-size microcatheters designed for pushability and trackability through small and tortuous vessels. The small outer diameter allows you to get deeper into the vasculature and still deliver the same spherical and non-spherical embolics of larger diameter microcatheters.

Merit Maestro® Microcatheters

Merit Maestro Microcatheters are designed to deploy coils up to 0.018″ and embolics up to and including 900 µm. Its swan neck design helps you seat the catheter in the vessel, reducing the recoiling effect of the embolic agent as it is introduced. Other features include a flexible distal region designed for atraumatic vessel entry and hydrophilic coating for smooth traction through tortuous anatomy.

True Form™ Reshapable Guide Wires

The True Form Reshapable Guide Wire is a 0.014″ guide wire designed with the ability to be shaped multiple times and keep its shape during procedures. The hydrophilic coating and flexible shaft help you navigate tortuous anatomy while the stainless steel core gives you excellent support for devices.
