This article compares two approaches side by side to clarify how they differ in principle and practice. 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. 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)
Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting.
Balloon angioplasty vs Stenting: Key Differences
Angioplasty alone may suffice for short, compliant lesions, whereas stenting is added when there is significant recoil or a flow-limiting dissection. A 'leave nothing behind' approach avoids a permanent implant, but a stent secures a durable lumen when needed. Drug-coated balloons have expanded the role of stent-free strategies. The decision is made during the procedure based on the artery's response.
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
- INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals.
- Access sheath sizing should match the planned devices to limit access-site complications.
- Embolic protection is often paired with atherectomy to capture dislodged debris.
Frequently Asked Questions
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.
Who decides which PAD device to use?
A vascular specialist selects devices based on lesion characteristics; this content is educational and not a treatment recommendation.
Clinical and Technical Context
INVAMED's TemREN atherectomy system is positioned for peripheral plaque modification. Access sheath sizing should match the planned devices to limit access-site complications. Use is guided by lesion morphology and clinician preference. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. INVAMED's Guardian protection device is designed for this distal-capture role. INVAMED's Invaducer introducer sheath sets support the access step of peripheral interventions. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. INVAMED's PTA balloon range is designed to cover common peripheral vessel sizes. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals. Embolic protection is often paired with atherectomy to capture dislodged debris. 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. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination.
