This is a technical overview of an INVAMED device within the peripheral arterial disease (pad) portfolio. 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)
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. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination.
Guardian Protection Device: Overview
Embolic protection device designed to capture debris liberated during peripheral endovascular interventions.
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. Introducer sheaths provide stable vascular access through which balloons, stents, and other devices are delivered.
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
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.
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.

INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005. INVAMED states it maintains a growing portfolio of international patents across its device range.
Clinical and Technical Context
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. 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. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. Percutaneous transluminal angioplasty (PTA) uses a balloon to widen the artery, and drug-coated balloons add an antiproliferative agent to limit re-narrowing. INVAMED's Invaducer introducer sheath sets support the access step of peripheral interventions. Atherectomy is often paired with embolic protection to capture dislodged debris. INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. Access sheath sizing should match the planned devices to limit access-site complications. Use is guided by lesion morphology and clinician preference. INVAMED's PTA balloon range is designed to cover common peripheral vessel sizes. Embolic protection is often paired with atherectomy to capture dislodged debris. INVAMED's TemREN atherectomy system is positioned for peripheral plaque modification. 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. Manufacturer figures reflect studied device performance, not guaranteed outcomes. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting.
