Embolotherapy Solutions

Experience Embolotherapy

Merit Medical’s Embolotherapy Portfolio reflects a commitment to delivering clinically proven and data-backed embolization results.

Our proprietary embolic products are the most studied on the market and allow for efficient and safe delivery and predictable outcomes. To complement our offerings, we provide excellent ongoing customer service to ensure you have the tools you need for your procedures.


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.

HepaSphere™ Microspheres (Outside US Only)

HepaSphere Microspheres are calibrated, spherical, hydrophilic microspheres made with a proprietary copolymer design that allows them to expand approximately 4x their dry-state matter, providing you a completer and more targeted occlusion of the blood vessels.

Learn More

QuadraSphere® Microspheres (US Only)

QuadraSphere Microspheres are soft and easily conform to the vessel lumen for complete occlusion that offers several benefits, including decreasing the risk of vessel recanalization,2 enabling greater tumor necrosis,3,4 and enhancing the embolic effect.2

EmboCube® Embolization Gelatin

Merit Medical’s EmboCube Embolization Gelatin brings speed, precision, and consistency to gelatin foam. EmboCube is uniformly cut gelatin foam pre-loaded into a Medallion® Syringe, allowing for faster preparation and accurate delivery. Also available in a simple kit for your convenience.

Learn More

Torpedo™ Gelatin Foam

Torpedo Gelatin Foam provides you with a preshaped gelatin foam loaded into a cartridge with an optional blunt stylet, removing the need for manual foam shaping, offering fast and easy attachment to the catheter for delivery. Easy to prepare and use, Torpedo Gelatin foam requires only hydration with a 50:50 saline-to-contrast mixture.

Bearing nsPVA® Embolization Particles

Bearing nsPVA Embolization Particles are irregularly shaped, biocompatible, hydrophilic, nonresorbable particles produced from polyvinyl alcohol. These embolization 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.

Learn More

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.

Tenor® Steerable Guidewires

Exceptional pushability and torqueability are combined in the Tenor Steerable Guidewire to facilitate precise navigation in challenging anatomy during your embolic procedures. Market evaluation showed that more than 80% of users rated the Tenor 0.018″ as superior or equivalent to their current wire across all key product attributes.5
