This unique blend ensures a stable and cohesive embolus formation upon contact with blood, while maintaining non-adhesive properties to preserve the integrity of the vessel walls. Libro’s EVOH component guarantees durability and biocompatibility, ensuring long-term patient safety.
The solubility in DMSO allows for delivery through microcatheters, enhancing the precision of application and minimizing the risk of non-target embolization. Additionally, the inclusion of Tantalum powder ensures superior radiopacity, providing clinicians with real-time monitoring capabilities and ensuring precise placement during procedures.
Choose Libro for a reliable, non-adhesive, and precisely controllable embolization agent, setting new standards in patient care and procedural success.
Libro is a non-adhesive liquid embolic agent comprised of EVOH (ethylene vinyl alcohol) copolymer dissolved in DMSO (dimethyl sulfoxide), and suspended micronized tantalum powder to provide contrast for visualization under fluoroscopy.

EVOH Base (Ethylene Vinyl Alcohol Copolymer)
- Stable Embolic Matrix: Once injected, the EVOH solution solidifies upon contact with blood or aqueous medium, forming an occlusive cast within the targeted vasculature.
- Non-Adhesive: Minimizes risk of catheter entrapment, enabling smoother microcatheter withdrawal post-embolization.
- Non-Adhesive: Minimizes risk of catheter entrapment, enabling smoother microcatheter withdrawal post-embolization.
DMSO Solvent
- Uniform Dispersion: Maintains the EVOH in a liquid state until injection, allowing for precise and controlled delivery.
- Gradual Precipitation: The polymer solidifies from the outer surface inward, helping operators monitor and fine-tune deposition patterns.
- Gradual Precipitation: The polymer solidifies from the outer surface inward, helping operators monitor and fine-tune deposition patterns.
辐射能力
- Integrated Tantalum Powder (or similar radiopaque agent) ensures fluoroscopic visibility, enabling real-time feedback on embolic material positioning.
