This guide offers an educational, technical overview of peripheral arterial disease (pad) and the device technologies used in this field. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. 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)
Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. 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.
Core Technologies and Options
Balloon Angioplasty (PTA). Percutaneous transluminal angioplasty inflates a balloon within the narrowed artery to compress plaque and widen the lumen, restoring flow. It is a foundational PAD technique, often used alone or as preparation before stenting. Drug-Coated Balloons (DCB). A drug-coated balloon delivers an antiproliferative drug — commonly paclitaxel — to the artery wall during inflation to reduce the risk of restenosis. It leaves no permanent implant behind, which can be advantageous in certain anatomies. Atherectomy. Atherectomy removes or modifies atherosclerotic plaque, which is especially useful in calcified lesions that resist balloon dilation. Debulking plaque can improve vessel compliance and the effect of subsequent balloon or drug therapy. Peripheral Stenting. Peripheral stents scaffold an artery open after angioplasty when the vessel recoils or dissects, maintaining the widened lumen. Self-expanding nitinol stents are common in mobile segments like the femoropopliteal artery. Embolic Protection. Embolic protection devices capture plaque or clot fragments dislodged during an intervention so they do not travel downstream. They are frequently used alongside atherectomy or in lesions with a high embolic risk. Vascular Access Sheaths. Introducer sheaths provide stable vascular access through which balloons, stents, and other devices are delivered. Sheath French size and length must match the intended devices and access site.
Comparing the Approaches
Atherectomy vs Balloon angioplasty. Balloon angioplasty widens an artery by compressing and stretching plaque, while atherectomy removes or modifies plaque tissue. Atherectomy adds procedural steps and often embolic protection; angioplasty is simpler but may struggle with hard calcium. Drug-coated balloon vs Drug-eluting stent. A drug-coated balloon delivers an antiproliferative drug without leaving an implant, while a drug-eluting stent both scaffolds and elutes drug. Both strategies target restenosis reduction through local drug delivery. Balloon angioplasty vs Stenting. Angioplasty alone may suffice for short, compliant lesions, whereas stenting is added when there is significant recoil or a flow-limiting dissection. Drug-coated balloons have expanded the role of stent-free strategies.

Key Considerations
- Manufacturer figures reflect studied device performance, not guaranteed outcomes.
- Embolic protection is often paired with atherectomy to capture dislodged debris.
- INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals.
Frequently Asked Questions
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.
Does INVAMED make a drug-coated balloon?
Yes. The Extender paclitaxel drug-coated balloon is INVAMED's peripheral drug-delivery balloon.
