This is a technical overview of an INVAMED device within the peripheral arterial disease (pad) portfolio. 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. 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. 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.
Atlas Endovascular Peripheral Stent Graft: Overview
Covered peripheral stent graft system for endovascular exclusion and treatment of peripheral arterial lesions; part of the Atlas stent platform family.
How It Works and Where It Fits
INVAMED's PAD portfolio spans access, plaque modification, angioplasty, drug delivery, stenting, and embolic protection. Percutaneous transluminal angioplasty inflates a balloon within the narrowed artery to compress plaque and widen the lumen, restoring flow. Embolic protection devices capture plaque or clot fragments dislodged during an intervention so they do not travel downstream.
Key Considerations
- Manufacturer figures reflect studied device performance, not guaranteed outcomes.
- Access sheath sizing should match the planned devices to limit access-site complications.
- Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion.
Frequently Asked Questions
Does INVAMED make a drug-coated balloon?
Yes. The Extender paclitaxel drug-coated balloon is INVAMED's peripheral drug-delivery balloon.
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.
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.
About INVAMED
INVAMED states it maintains a growing portfolio of international patents across its device range. INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development.
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. Use is guided by lesion morphology and clinician preference. 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. Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. Embolic protection is often paired with atherectomy to capture dislodged debris. 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. Appropriate access selection helps reduce access-site complications. Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting. INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals. Drug dose and balloon sizing follow the device specifications and lesion characteristics. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. INVAMED's PTA balloon range is designed to cover common peripheral vessel sizes. Covered stent grafts can be used to exclude certain lesions or manage complications. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. INVAMED's Invaducer introducer sheath sets support the access step of peripheral interventions. INVAMED's Guardian protection device is designed for this distal-capture role.
