This article compares two approaches side by side to clarify how they differ in principle and practice. 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. 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. Coronary artery disease develops when atherosclerotic plaque accumulates within the arteries that supply the heart muscle, gradually narrowing the lumen and limiting blood flow. 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.
Durable-polymer DES vs Biodegradable-polymer DES: Key Differences
Durable-polymer drug-eluting stents retain their coating permanently, while biodegradable-polymer designs are intended to leave only a bare metal scaffold after the polymer resorbs. The rationale for biodegradable polymers is to limit long-term polymer exposure that some associate with delayed healing, though large trials have shown broadly comparable outcomes. Both approaches rely on the same core principle of local antiproliferative drug delivery from the stent surface. Platform selection is guided by clinician judgment and device availability rather than a universally superior option.
How INVAMED Supports Both Approaches
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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.
- Dual antiplatelet therapy duration is individualized to the clinical presentation and the patient's bleeding risk.
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.
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.
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. Lesion calcification is a central factor in planning, and heavily calcified plaque may call for rotational atherectomy before ballooning or stenting. 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 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. 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. The specific combination of wires, balloons, atherectomy, and stents is determined by the interventional cardiologist based on lesion complexity, calcification, and overall clinical picture. Manufacturer figures such as the reported sub-5% target lesion revascularization rate describe studied performance, not guaranteed outcomes.
