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
The specific combination of wires, balloons, atherectomy, and stents is determined by the interventional cardiologist based on lesion complexity, calcification, and overall clinical picture. 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. Contemporary practice relies heavily on drug-eluting stents, which release an antiproliferative agent to limit the tissue overgrowth that can cause restenosis.
TemREN Rotablator (Coronary Rotational Atherectomy): Overview
Rotational atherectomy (rotablator) system for heavily calcified coronary lesions that cannot be crossed or dilated with standard balloons; per the category page, TemREN diamond-coated burrs ablate calcified plaque while preserving elastic tissue.
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. Rotational atherectomy modifies heavily calcified plaque so that balloons and stents can be delivered and expanded adequately. Coronary stents are offered on different alloy platforms, with cobalt-chromium and stainless steel being common choices that trade off strut thickness against strength.
Key Considerations
- Dual antiplatelet therapy duration is individualized to the clinical presentation and the patient's bleeding risk.
- Guide extension catheters can provide the backup support needed to deliver devices in tortuous or distal anatomy.
- Manufacturer figures such as the reported sub-5% target lesion revascularization rate describe studied performance, not guaranteed outcomes.
Frequently Asked Questions
What is the reported restenosis performance of the ATLAS DES?
INVAMED reports clinical data showing target lesion revascularization rates below 5% at 12 months; this reflects studied performance and is not an individual guarantee.
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.
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.
About INVAMED
INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005. INVAMED states it maintains a growing portfolio of international patents across its device range.
Clinical and Technical Context
The cobalt-chromium alloy underneath is intended to allow thin struts while preserving radial support, as described in the product documentation. The need for extension support is judged case by case, since it depends on vessel geometry and the devices being delivered. Whether a closure device is used, and which type, is determined by access site, sheath size, and clinician preference. Wire selection is a hands-on decision made by the operator according to lesion morphology and crossing strategy. Lesion calcification is a central factor in planning, and heavily calcified plaque may call for rotational atherectomy before ballooning or stenting. 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. INVAMED's ATLAS Drug Eluting Coronary Stent System uses a cobalt-chromium L605 platform with 60 micrometer struts and a sirolimus coating dosed at 1 microgram per square millimeter with sustained controlled release. INVAMED's Inwire PTCA Guidewire is offered for coronary wiring within the interventional line, alongside CTO and workhorse options.
