This article compares two approaches side by side to clarify how they differ in principle and practice. 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)
Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. 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.
Drug-coated balloon vs Drug-eluting stent: Key Differences
A drug-coated balloon delivers an antiproliferative drug without leaving an implant, while a drug-eluting stent both scaffolds and elutes drug. Leaving no metal behind can be attractive in flexion segments, but a stent may be needed when the vessel recoils or dissects. Both strategies target restenosis reduction through local drug delivery. Selection depends on lesion behavior after dilation and clinician judgment.
How INVAMED Supports Both Approaches
INVAMED's PAD portfolio spans access, plaque modification, angioplasty, drug delivery, stenting, and embolic protection. Balloon and stent size ranges are provided in product documentation to cover common peripheral anatomy. INVAMED offers a broad PAD portfolio: Invaducer sheaths, TemREN atherectomy, PTA and Extender drug-coated balloons, Atlas peripheral stent graft, and the Guardian protection device.
Key Considerations
- Manufacturer figures reflect studied device performance, not guaranteed outcomes.
- 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
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.
What is the regulatory status of these devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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.
About INVAMED
INVAMED states it holds more than 100 international patents across its device portfolio. INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development.
Clinical and Technical Context
INVAMED's TemREN atherectomy system is positioned for peripheral plaque modification. INVAMED's Invaducer introducer sheath sets support the access step of peripheral interventions. 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. Use is guided by lesion morphology and clinician preference. 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. Covered stent grafts can be used to exclude certain lesions or manage complications. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. 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. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. Manufacturer figures reflect studied device performance, not guaranteed outcomes. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. Appropriate access selection helps reduce access-site complications. Atherectomy is often paired with embolic protection to capture dislodged debris.
