This article compares two approaches side by side to clarify how they differ in principle and practice. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Peripheral Arterial Disease (PAD)
Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist.
Atherectomy vs Stenting: Key Differences
Atherectomy modifies or removes plaque, while stenting scaffolds the vessel open; they address different aspects of a lesion. Debulking with atherectomy can reduce the need for a stent in some calcified lesions, or improve stent expansion when one is used. Each carries distinct risks — embolization for atherectomy, in-stent restenosis for stents. Operators often sequence these tools based on lesion character.
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
- Manufacturer figures reflect studied device performance, not guaranteed outcomes.
- Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion.
- Access sheath sizing should match the planned devices to limit access-site complications.
Frequently Asked Questions
Does INVAMED make a drug-coated balloon?
Yes. The Extender paclitaxel drug-coated balloon is INVAMED's peripheral drug-delivery balloon.
Why use embolic protection?
It captures plaque or clot fragments dislodged during treatment so they do not travel downstream; it is often paired with atherectomy.
What atherectomy device does INVAMED make?
INVAMED's TemREN system is positioned for peripheral atherectomy and plaque modification, often used with the Guardian embolic protection device.
Clinical and Technical Context
Atherectomy is often paired with embolic protection to capture dislodged debris. Embolic protection is often paired with atherectomy to capture dislodged debris. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. Access sheath sizing should match the planned devices to limit access-site complications. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. INVAMED's PTA balloon range is designed to cover common peripheral vessel sizes. Covered stent grafts can be used to exclude certain lesions or manage complications. INVAMED's Invaducer introducer sheath sets support the access step of peripheral interventions. INVAMED's Guardian protection device is designed for this distal-capture role. INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting. Use is guided by lesion morphology and clinician preference. Peripheral arterial disease is the narrowing of arteries outside the heart — most often in the legs — due to atherosclerotic plaque, reducing blood flow to the limbs. Balloon diameter and length are matched to the vessel to avoid over- or under-dilation.
