The ATLAS stainless steel coronary stent system is INVAMED's bare-metal stent platform, designed to deliver structural radial strength and dependable deliverability for percutaneous coronary intervention. As a bare-metal alternative to the cobalt-chromium drug-eluting ATLAS platform, this stainless-steel system is intended for interventional cardiology teams who determine that a non-drug-eluting stent is appropriate for a given clinical scenario. This overview reflects design information described on invamed.com; individual device selection is a physician-directed clinical decision.
What Is the ATLAS Stainless Steel Stent Platform?
Stainless steel remains a well-established material in coronary stent manufacturing, with a long history of clinical use in interventional cardiology. The ATLAS stainless steel system is built to provide:
- Durable radial strength intended to maintain vessel patency after deployment
- Reliable trackability for navigation through the coronary vasculature during placement
- Structural performance suited for a range of coronary lesion types, including certain complex or calcified presentations
- A bare-metal design without a drug-eluting coating, distinguishing it from the ATLAS cobalt-chromium DES platform
How Does It Compare Structurally to the Cobalt-Chromium ATLAS Platform?
Because stainless steel has different mechanical properties than cobalt-chromium alloys, stent platforms built from stainless steel generally use comparatively thicker struts to achieve equivalent radial strength. This is a well-documented material trade-off in stent engineering rather than a limitation specific to any one manufacturer. The ATLAS stainless steel system is positioned as a dependable, cost-conscious option for cases where a bare-metal platform is clinically appropriate, while the cobalt-chromium ATLAS DES platform targets thinner-strut, drug-eluting applications.
When Might a Bare-Metal Platform Be Considered?
The decision to use a bare-metal stent such as the ATLAS stainless steel system, rather than a drug-eluting platform, depends on individualized clinical factors that the treating interventional cardiologist evaluates, which may include:
- Patient bleeding risk profile and anticipated ability to complete a prescribed antiplatelet therapy regimen
- Upcoming non-cardiac surgery that may require a shorter interruption of antiplatelet medication
- Specific lesion or vessel characteristics
- Overall procedural and institutional considerations
This determination is made on a case-by-case basis and is not standardized across all patients.

Frequently Asked Questions
What is the main difference between the ATLAS stainless steel and cobalt-chromium platforms?
The primary difference is the absence of a drug-eluting coating and the underlying alloy: the stainless steel system is a bare-metal platform, while the cobalt-chromium ATLAS platform is available as a sirolimus-coated drug-eluting stent with generally thinner struts.
Is a bare-metal stent less effective than a drug-eluting stent?
Bare-metal and drug-eluting stents serve overlapping but distinct clinical roles. Drug-eluting stents are generally designed to reduce restenosis risk through localized drug delivery, while bare-metal stents may be preferred in specific scenarios such as shorter anticipated antiplatelet therapy duration. Neither is universally superior; appropriateness depends on the individual case.
