This is a technical overview of an INVAMED device within the peripheral arterial disease (pad) portfolio. 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)
Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia.
Extender PTA Drug Released Peripheral Balloon (Paclitaxel DCB): Overview
Paclitaxel drug-coated balloon for peripheral transluminal angioplasty (PTA) that releases antiproliferative agent rapidly into the vessel wall upon balloon inflation to inhibit neointimal hyperplasia and mitigate restenosis in femoral or popliteal arteries.
Technical Specifications

How It Works and Where It Fits
INVAMED's PAD portfolio spans access, plaque modification, angioplasty, drug delivery, stenting, and embolic protection. Embolic protection devices capture plaque or clot fragments dislodged during an intervention so they do not travel downstream. Atherectomy removes or modifies atherosclerotic plaque, which is especially useful in calcified lesions that resist balloon dilation.
Key Considerations
- INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals.
- Manufacturer figures reflect studied device performance, not guaranteed outcomes.
- Embolic protection is often paired with atherectomy to capture dislodged debris.
Frequently Asked Questions
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.
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.
What is the regulatory status of these devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Clinical and Technical Context
INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. Manufacturer figures reflect studied device performance, not guaranteed outcomes. Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting. Access sheath sizing should match the planned devices to limit access-site complications. INVAMED's PTA balloon range is designed to cover common peripheral vessel sizes. Appropriate access selection helps reduce access-site complications. Covered stent grafts can be used to exclude certain lesions or manage complications. INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals. Atherectomy is often paired with embolic protection to capture dislodged debris. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. 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. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. Balloon diameter and length are matched to the vessel to avoid over- or under-dilation. 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.
