What Is the Atlas Peripheral Stent System Designed For?
The Atlas Peripheral Stent System is indicated for use in lesions at risk of sudden or threatened closure following percutaneous transluminal angioplasty (PTA), as well as lesions considered at elevated risk of restenosis after PTA, within the common iliac, external iliac, superficial femoral, proximal popliteal, or subclavian arteries. It is designed to improve luminal diameter across a range of lesion lengths, supporting stent placement in vessels with diameters generally between 5 mm and 8 mm.
What Are the Key Design Features?
The Atlas Peripheral Stent System is built around several design characteristics intended to support accurate deployment and vessel conformability:
- Material: The stent is composed of medical-grade nitinol (nickel-titanium alloy), a self-expanding material selected for its flexibility and shape-memory properties.
- Construction: The stent is laser-cut, a manufacturing method used to help achieve consistent strut geometry.
- Length coverage: The system is available to address luminal diameters across lesion lengths ranging from approximately 20 mm to 200 mm, supporting placement across both short focal lesions and longer diseased segments.
- Delivery profile: The stent is housed within a 6F (2.1 mm maximum outer diameter) delivery system.
How Is the Delivery System Constructed?
The Atlas delivery system uses a triaxial shaft design, consisting of:
- An outer shaft that stabilizes the overall delivery system
- A middle shaft that protects and holds the stent in position between two radiopaque markers
- An inner shaft that provides a guidewire lumen
This construction is intended to support controlled, precise stent placement during deployment. The delivery system is compatible with 0.035 in (0.89 mm) guidewires and is available in 80 cm and 120 cm catheter lengths, using a pull-back deployment mechanism.
Why Is Nitinol Used for This Stent Platform?
Nitinol is a nickel-titanium alloy widely used in self-expanding peripheral stents because of its combination of flexibility and shape-memory characteristics, which allow the stent to conform to vessel curvature and withstand repetitive mechanical stress — a relevant consideration in segments like the superficial femoral and popliteal arteries that cross the hip and knee joints. The self-expanding mechanism also allows the stent to gradually reach its intended diameter after deployment, rather than being expanded solely by balloon force.
How Does the Atlas Fit Into a Broader PAD Treatment Strategy?
The Atlas Peripheral Stent System is one component within INVAMED's broader peripheral arterial disease portfolio, which also includes PTA balloon catheters, drug-coated balloon technology, and atherectomy systems. Physicians may use the Atlas stent following angioplasty when additional structural support is indicated, based on individual lesion characteristics and procedural findings.
Frequently Asked Questions
What vessels is the Atlas Peripheral Stent System intended for?
The device is intended for use in the common iliac, external iliac, superficial femoral, proximal popliteal, or subclavian arteries, particularly in lesions at elevated risk of closure or restenosis following angioplasty. Suitability for a specific vessel and lesion is determined by the treating physician.
What is the delivery profile of the Atlas stent system?
The stent is housed within a 6F (2.1 mm maximum outer diameter) delivery system compatible with 0.035 in guidewires, and is available in 80 cm and 120 cm catheter lengths.
