This is a technical overview of an INVAMED device within the coronary artery disease & cardiac interventions portfolio. When a narrowing becomes flow-limiting, patients may experience angina on exertion, and an abrupt plaque rupture with thrombosis can precipitate a myocardial infarction. 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. When a narrowing becomes flow-limiting, patients may experience angina on exertion, and an abrupt plaque rupture with thrombosis can precipitate a myocardial infarction. Contemporary practice relies heavily on drug-eluting stents, which release an antiproliferative agent to limit the tissue overgrowth that can cause restenosis.
Extender Drug Eluting PTCA Balloon Catheter (Paclitaxel): Overview
Paclitaxel drug-eluting PTCA balloon catheter that delivers antiproliferative drug to the coronary vessel wall during inflation without leaving a permanent implant; primary uses include in-stent restenosis treatment and small vessel disease where stent placement is undesirable.

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. The guidewire is the rail on which balloons and stents are advanced, and different tip loads and coatings suit workhorse versus chronic total occlusion (CTO) work. After the sheath is removed, the arterial access site must be closed, either with manual compression or with a vascular closure device.
Key Considerations
- Manufacturer figures such as the reported sub-5% target lesion revascularization rate describe studied performance, not guaranteed outcomes.
- All INVAMED coronary devices are intended for use by trained interventional cardiologists under fluoroscopic guidance and per the IFU.
- Dual antiplatelet therapy duration is individualized to the clinical presentation and the patient's bleeding risk.
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.
Does INVAMED make a drug-coated coronary balloon?
Yes. The Extender Drug Eluting PTCA Balloon Catheter carries a paclitaxel coating for local drug delivery, such as in-stent restenosis or small-vessel disease.
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
Thin-strut cobalt-chromium platforms are intended to balance deliverability with radial support in a range of vessel sizes. Manufacturer figures such as the reported sub-5% target lesion revascularization rate describe studied performance, not guaranteed outcomes. INVAMED's TemREN Rotablator uses diamond-coated burrs that ablate calcified plaque while preserving elastic tissue, according to the manufacturer. Dual antiplatelet therapy duration is individualized to the clinical presentation and the patient's bleeding risk. INVAMED's Atlas line spans a cobalt-chromium drug-eluting version, a bare cobalt-chromium version described as offering high radial strength with minimal recoil, and a stainless-steel version. The need for extension support is judged case by case, since it depends on vessel geometry and the devices being delivered. INVAMED's Extender Drug Eluting PTCA Balloon Catheter carries a paclitaxel coating for this local drug-delivery role. INVAMED's Inwire PTCA Guidewire is offered for coronary wiring within the interventional line, alongside CTO and workhorse options.
