Below is an educational, technical answer to a question many patients and clinicians ask. 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)
Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. 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.
How does a drug-coated balloon work?
A drug-coated balloon is coated with an antiproliferative drug that transfers to the artery wall during a brief inflation. The drug is intended to inhibit the cell proliferation that causes restenosis, without leaving a permanent implant. INVAMED's Extender paclitaxel balloon is an example of this technology. Balloon sizing and inflation follow the device instructions and lesion needs.
What This Means in Practice
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. Embolic protection is often paired with atherectomy to capture dislodged debris.
Key Considerations
- 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.
- Manufacturer figures reflect studied device performance, not guaranteed outcomes.
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.
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. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. Use is guided by lesion morphology and clinician preference. Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. INVAMED's Invaducer introducer sheath sets support the access step of peripheral interventions. Manufacturer figures reflect studied device performance, not guaranteed outcomes. Access sheath sizing should match the planned devices to limit access-site complications. INVAMED's Guardian protection device is designed for this distal-capture role. 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. 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. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. Covered stent grafts can be used to exclude certain lesions or manage complications.
