Below is an educational, technical answer to a question many patients and clinicians ask. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. 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. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist.
What is in-stent restenosis and how is it treated?
In-stent restenosis is re-narrowing inside a previously placed stent, caused mainly by tissue overgrowth. It can be treated with repeat angioplasty, drug-coated balloons, atherectomy, or additional stenting depending on the pattern. Local drug delivery is a common strategy to limit recurrence. The approach is tailored by the treating physician.
What This Means in Practice
Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. 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
- Embolic protection is often paired with atherectomy to capture dislodged debris.
- 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.
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.
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.
Does INVAMED make a drug-coated balloon?
Yes. The Extender paclitaxel drug-coated balloon is INVAMED's peripheral drug-delivery balloon.

Clinical and Technical Context
Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. 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 PAD devices are for use by trained vascular specialists per the IFU and local approvals. Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting. Atherectomy is often paired with embolic protection to capture dislodged debris. Embolic protection is often paired with atherectomy to capture dislodged debris. 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. 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. Covered stent grafts can be used to exclude certain lesions or manage complications. Drug dose and balloon sizing follow the device specifications and lesion characteristics. Appropriate access selection helps reduce access-site complications. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. Access sheath sizing should match the planned devices to limit access-site complications. Balloon diameter and length are matched to the vessel to avoid over- or under-dilation.
