Below is an educational, technical answer to a question many patients and clinicians ask. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. 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. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting.
How long does a leg stent last?
Peripheral stents are permanent implants intended to keep the artery open long term. Durability varies with lesion location, length, calcification, and whether restenosis develops within the stent. Antiplatelet therapy and risk-factor control support long-term patency. Individual outlook is best discussed with the vascular specialist.
What This Means in Practice
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.
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.
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
Appropriate access selection helps reduce access-site complications. 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. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. INVAMED's PTA balloon range is designed to cover common peripheral vessel sizes. Embolic protection is often paired with atherectomy to capture dislodged debris. 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. INVAMED's TemREN atherectomy system is positioned for peripheral plaque modification. INVAMED's Guardian protection device is designed for this distal-capture role. Manufacturer figures reflect studied device performance, not guaranteed outcomes. 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. Drug dose and balloon sizing follow the device specifications and lesion characteristics. Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting. 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. Access sheath sizing should match the planned devices to limit access-site complications. Covered stent grafts can be used to exclude certain lesions or manage complications. INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels.
