This is a technical overview of an INVAMED device within the coronary artery disease & cardiac interventions portfolio. During PCI a lesion is usually crossed with a guidewire, prepared with a balloon, and in most cases scaffolded with a stent that holds the vessel open. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Coronary Artery Disease and Percutaneous Coronary Intervention
When a narrowing becomes flow-limiting, patients may experience angina on exertion, and an abrupt plaque rupture with thrombosis can precipitate a myocardial infarction. Percutaneous coronary intervention (PCI) is a catheter-based approach that reaches the coronary arteries through a small arterial access point, typically the radial or femoral artery. Coronary artery disease develops when atherosclerotic plaque accumulates within the arteries that supply the heart muscle, gradually narrowing the lumen and limiting blood flow.
Atlas Coronary Stent System Cobalt Chromium: Overview
A cobalt-chromium coronary stent delivering durable radial strength and excellent trackability, suited for complex or calcified coronary lesions with minimal recoil; offered as a BMS or DES platform.
Technical Specifications

How It Works and Where It Fits
INVAMED groups its coronary portfolio around the sequence of a PCI case, offering access, lesion preparation, drug delivery, scaffolding, and closure devices. A drug-eluting stent combines a thin metallic scaffold with a polymer coating that releases an antiproliferative drug into the vessel wall over time. Sirolimus is a widely used antiproliferative agent that interrupts the cell-cycle signaling responsible for excessive tissue growth inside a stent.
Key Considerations
- Lesion calcification is a central factor in planning, and heavily calcified plaque may call for rotational atherectomy before ballooning or stenting.
- All INVAMED coronary devices are intended for use by trained interventional cardiologists under fluoroscopic guidance and per the IFU.
- Thin-strut cobalt-chromium platforms are intended to balance deliverability with radial support in a range of vessel sizes.
Frequently Asked Questions
What is the INVAMED drug-eluting stent called?
INVAMED's drug-eluting coronary stent is the ATLAS Drug Eluting Coronary Stent System, built on a cobalt-chromium L605 platform with a sirolimus coating.
Who decides between PCI and bypass surgery?
That decision is made by a clinical heart team based on coronary anatomy and individual factors; this article is educational and not medical advice.
What drug does the ATLAS stent release?
According to INVAMED, the ATLAS DES elutes sirolimus at 1 microgram per square millimeter with a sustained controlled-release profile.

Clinical and Technical Context
Whether a closure device is used, and which type, is determined by access site, sheath size, and clinician preference. INVAMED's coronary portfolio includes guiding catheters, extension catheters, and microcatheters intended to support crossing and delivery in demanding anatomy. During PCI a lesion is usually crossed with a guidewire, prepared with a balloon, and in most cases scaffolded with a stent that holds the vessel open. INVAMED's TemREN Rotablator uses diamond-coated burrs that ablate calcified plaque while preserving elastic tissue, according to the manufacturer. Percutaneous coronary intervention (PCI) is a catheter-based approach that reaches the coronary arteries through a small arterial access point, typically the radial or femoral artery. Dual antiplatelet therapy duration is individualized to the clinical presentation and the patient's bleeding risk. The cobalt-chromium alloy underneath is intended to allow thin struts while preserving radial support, as described in the product documentation. Wire selection is a hands-on decision made by the operator according to lesion morphology and crossing strategy.
