"(《世界人权宣言》) Atlas™ Venous Stent, introduced by Invamed-a 全球医疗设备制造商—is meticulously crafted for venous outflow restoration and chronic venous insufficiency management. Leveraging a 自我膨胀 nitinol design, Atlas™ offers strong radial force, adaptive conformability, and minimal recoil, supporting 经久耐用 patency in challenging venous anatomies.
Self-Expanding Nitinol Framework
Delivers consistent radial force to maintain lumen patency, especially in large, compressible venous segments.
High Conformability
Adapts to tortuous or dynamic venous structures (e.g., iliac vein, femoral vein), minimizing stress at stent edges and promoting stable apposition.
Minimal Recoil & Migration
Engineered for durable scaffolding, preserving vessel diameter and reducing the risk of stent migration under variable venous pressures.
Optimized for Venous Hemodynamics
Large cell design fosters robust flow, reducing intraluminal pressure gradients and supporting potential reduction in venous hypertension symptoms.
Wide Clinical Utility
Indicated for iliofemoral venous outflow obstructions, post-thrombotic syndrome, or venous stenoses from extrinsic compression or scar tissue.
禁忌症
Severe vessel tortuosity or diameter mismatch preventing stent passage, active local infection in the venous target, or contraindications to endovascular procedures.
