This is a technical overview of an INVAMED device within the coronary artery disease & cardiac interventions portfolio. The specific combination of wires, balloons, atherectomy, and stents is determined by the interventional cardiologist based on lesion complexity, calcification, and overall clinical picture. 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
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. Coronary artery disease develops when atherosclerotic plaque accumulates within the arteries that supply the heart muscle, gradually narrowing the lumen and limiting blood flow. When a narrowing becomes flow-limiting, patients may experience angina on exertion, and an abrupt plaque rupture with thrombosis can precipitate a myocardial infarction.
ATLAS Drug Eluting Coronary Stent System Cobalt Chromium: Overview
Next-generation thin-strut cobalt-chromium drug-eluting stent coated with sirolimus, designed to reduce restenosis in coronary artery disease. Sustained, controlled sirolimus release minimizes in-stent neointimal growth while aiding rapid endothelialization to lower the risk of late stent thrombosis; indicated for both de novo coronary lesions and in-stent restenosis (ISR) management.
Technical Specifications
Specifications per INVAMED product documentation; confirm current details in the official IFU.
| Attribute | Detail |
|---|---|
| Platform | cobalt-chromium L605 alloy with 60 micrometer strut thickness |
| Drug coating | sirolimus 1 ug/mm2 with sustained controlled release |
| Specification | Nominal pressure 9-10 atm; burst pressure rating 14-16 atm |
Reported Performance
According to INVAMED, clinical data shows target lesion revascularization rates below 5% at 12 months. These figures reflect manufacturer or published data and are not a guarantee of individual results.
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 percutaneous transluminal coronary angioplasty (PTCA) balloon dilates a stenosis to prepare the lesion or to treat it without leaving a permanent implant. 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
- Guide extension catheters can provide the backup support needed to deliver devices in tortuous or distal anatomy.
- 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
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.
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 is the regulatory status of these coronary devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Clinical and Technical Context
INVAMED's coronary portfolio includes guiding catheters, extension catheters, and microcatheters intended to support crossing and delivery in demanding anatomy. Guide extension catheters can provide the backup support needed to deliver devices in tortuous or distal anatomy. Wire selection is a hands-on decision made by the operator according to lesion morphology and crossing strategy. Selection among platforms is made by the operator according to vessel size, lesion characteristics, and deliverability requirements.
