The Atlas Venous Stent is a self-expanding nitinol venous stent manufactured by INVAMED, engineered specifically for venous anatomy rather than adapted from arterial stent platforms. This overview summarizes its intended use, design characteristics, and clinical applications for interventional radiologists, vascular surgeons, and interventional cardiologists evaluating dedicated venous stent options.
What Is the Atlas Venous Stent?
The Atlas Venous Stent is a dedicated venous stent system designed for venous outflow restoration and management of chronic venous obstruction. It is built to address the distinct mechanical demands of the venous system, which differs substantially from the arterial circulation in pressure, flow dynamics, and susceptibility to extrinsic compression.
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
What Are the Design Features?
Atlas is built on a self-expanding nitinol platform with several design characteristics relevant to venous anatomy:
- Optimal radial force — engineered to resist external compression while accommodating the lower intraluminal pressure of the venous system compared to arteries
- Adaptive conformability — designed to flex with the venous anatomy through areas such as the iliofemoral segment, which is subject to hip flexion and pelvic movement
- Minimal recoil — intended to maintain the achieved luminal diameter after deployment
- Larger available diameters — sized to match the larger caliber of major venous structures compared to typical arterial vessels
These characteristics distinguish dedicated venous stents like Atlas from arterial stent platforms, which are generally engineered for higher-pressure, more rigid environments and are not designed for the flexibility and crush resistance venous anatomy requires.
What Are the Indications for Use?
The Atlas Venous Stent is indicated for use in cases of:
- Iliofemoral venous outflow obstruction
- May-Thurner syndrome (iliac vein compression)
- Post-thrombotic syndrome (PTS) with imaging-confirmed venous outflow obstruction
- Venous stenoses resulting from extrinsic compression or scar tissue formation
As with all endovascular devices, patient selection and procedural planning are determined by the treating physician based on imaging findings, clinical presentation, and individual anatomy.
How Is Atlas Positioned Within a Venous Intervention Workflow?
Atlas is typically used following diagnostic confirmation of venous outflow obstruction through duplex ultrasound, CT/MR venography, or intravascular ultrasound (IVUS). Physicians may perform balloon venoplasty to prepare the vessel prior to stent deployment, followed by careful sizing based on IVUS or venographic measurements to select the appropriate stent diameter and length.
Post-procedural anticoagulation protocols and follow-up imaging are typically determined by the treating institution's clinical pathway.
What Are the Considerations for Use?
All endovascular procedures carry inherent risks, including but not limited to stent thrombosis, migration, or restenosis. Suitability for venous stenting with any device, including Atlas, is determined by a physician based on a comprehensive evaluation. Clinicians should always refer to the official Instructions for Use (IFU) for complete indications, contraindications, warnings, and precautions.
Frequently Asked Questions
How does the Atlas Venous Stent differ from arterial stents?
Atlas is purpose-built for venous anatomy, with design priorities around flexibility, crush resistance, and accommodation of larger vessel diameters and lower intraluminal pressures — characteristics not typically optimized in arterial stent platforms.
What conditions is the Atlas Venous Stent intended to address?
It is intended for iliofemoral venous outflow obstruction, including cases arising from May-Thurner syndrome, post-thrombotic syndrome, and venous stenoses from extrinsic compression or scarring.
