Информация

Сайтът Stena Aortic Multi-Layer Flow Modulator is an advanced, self-expandable endovascular device engineered to promote controlled blood flow and aortic remodeling in a variety of aortic pathologies. Designed with a multi-layer tubular mesh structure, this stent optimizes laminar flow while providing robust radial support, conformability, and enhanced safety for complex aortic anatomies.

Multi-Layer Tubular Mesh
  • Five-Layer Design: The stent is meticulously knitted from a superalloy biomedical wire, forming five distinct layers that distribute wall stress and maintain a stable configuration.
  • Flow-Mediated Healing: The mesh’s micro-porosity fosters effective laminar flow within the aorta, supporting progressive thrombosis of the aneurysm sac in aneurysmal disease and enhanced remodeling in dissection scenarios.
  • Biocompatibility and Durability: The wire alloy is carefully selected for its high corrosion resistance, fatigue strength, and excellent conformability.
  • Self-Expanding Mechanism: Once deployed, the stent exerts controlled radial force to ensure secure apposition against the aortic wall, minimizing the risk of device migration.
  • Precise Fluoroscopic Visualization: Tantalum markers at both ends facilitate accurate placement under imaging guidance, ensuring correct proximal and distal landing zones.
  • Enhanced Safety: Intraoperative and follow-up imaging are streamlined, enabling clinicians to verify device expansion and position over time.
  • Sheath Lock Mechanism: The integrated sheath lock prevents premature stent deployment, providing operators with predictable and controlled release.
  • Hemostasis Valve: A specialized valve setup ensures minimal blood loss and stable guidewire management throughout the procedure.
