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. 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.
AngioTEN Vascular Closure System: Overview
Vascular closure device for arteriotomy closure after percutaneous catheterization procedures, providing hemostasis of the access site.
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. 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.
Key Considerations
- Guide extension catheters can provide the backup support needed to deliver devices in tortuous or distal anatomy.
- Thin-strut cobalt-chromium platforms are intended to balance deliverability with radial support in a range of vessel sizes.
- Dual antiplatelet therapy duration is individualized to the clinical presentation and the patient's bleeding risk.
Frequently Asked Questions
Are these coronary devices CE marked?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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 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.
Clinical and Technical Context
Thin-strut cobalt-chromium platforms are intended to balance deliverability with radial support in a range of vessel sizes. INVAMED's coronary portfolio includes guiding catheters, extension catheters, and microcatheters intended to support crossing and delivery in demanding anatomy. The need for extension support is judged case by case, since it depends on vessel geometry and the devices being delivered. Wire selection is a hands-on decision made by the operator according to lesion morphology and crossing strategy. INVAMED's Extender Drug Eluting PTCA Balloon Catheter carries a paclitaxel coating for this local drug-delivery role. Plaque modification is typically a preparatory step, and its use is decided by the operator based on the calcium burden seen on imaging. 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 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. INVAMED's ATLAS system elutes sirolimus at 1 microgram per square millimeter with a sustained controlled-release profile designed to cover the early healing window. INVAMED's Inwire PTCA Guidewire is offered for coronary wiring within the interventional line, alongside CTO and workhorse options.
