Below is an educational, technical answer to a question many patients and clinicians ask. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. 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. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist.
What is atherectomy?
Atherectomy is a catheter-based technique that removes or modifies atherosclerotic plaque from within an artery. It is particularly useful in calcified lesions where balloons alone may not adequately open the vessel. INVAMED's TemREN system is positioned for peripheral atherectomy. Because plaque fragments can be released, embolic protection is often used alongside it.
What This Means in Practice
Access sheath sizing should match the planned devices to limit access-site complications. 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.
Key Considerations
- Access sheath sizing should match the planned devices to limit access-site complications.
- 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.
Frequently Asked Questions
Is a stent always needed in PAD?
No. Many lesions are treated with angioplasty or drug-coated balloons alone; a stent is added when the vessel recoils or dissects.
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
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. INVAMED's Invaducer introducer sheath sets support the access step of peripheral interventions. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. Drug dose and balloon sizing follow the device specifications and lesion characteristics. INVAMED's TemREN atherectomy system is positioned for peripheral plaque modification. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. Manufacturer figures reflect studied device performance, not guaranteed outcomes. Balloon diameter and length are matched to the vessel to avoid over- or under-dilation. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. Atherectomy is often paired with embolic protection to capture dislodged debris. Appropriate access selection helps reduce access-site complications. INVAMED's Guardian protection device is designed for this distal-capture role. Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. Embolic protection is often paired with atherectomy to capture dislodged debris. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals. INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. 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.
