This article explains, in educational terms, atherectomy — how the technology works and where it fits. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. 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)
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. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting.
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. INVAMED's TemREN atherectomy system is positioned for peripheral plaque modification. Atherectomy is often paired with embolic protection to capture dislodged debris.
Design and Technical Notes
INVAMED's PAD portfolio spans access, plaque modification, angioplasty, drug delivery, stenting, and embolic protection. Access sheath sizing should match the planned devices to limit access-site complications. Manufacturer figures reflect studied device performance, not guaranteed outcomes.
Key Considerations
- INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals.
- 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
Are these 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.
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 Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. Atherectomy is often paired with embolic protection to capture dislodged debris. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. Balloon diameter and length are matched to the vessel to avoid over- or under-dilation. Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. 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 Guardian protection device is designed for this distal-capture role. Access sheath sizing should match the planned devices to limit access-site complications. Drug dose and balloon sizing follow the device specifications and lesion characteristics. Manufacturer figures reflect studied device performance, not guaranteed outcomes. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. Use is guided by lesion morphology and clinician preference.

Embolic protection is often paired with atherectomy to capture dislodged debris. Appropriate access selection helps reduce access-site complications.
