This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating peripheral arterial disease (pad) devices. 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)
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.
Regulatory Status and Manufacturing
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Portfolio and Sizing
Within this category, INVAMED lists devices such as TemREN Peripheral Atherectomy System, Extender PTA Drug Released Peripheral Balloon, Atlas Endovascular Peripheral Stent Graft, Guardian Protection Device, Invaducer Intraducer. Size ranges, materials, and configurations are detailed in product documentation and the applicable IFU.
Key Considerations
- Embolic protection is often paired with atherectomy to capture dislodged debris.
- Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting.
- INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals.
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.
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.
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.
Clinical and Technical Context
Covered stent grafts can be used to exclude certain lesions or manage complications. Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals. Balloon diameter and length are matched to the vessel to avoid over- or under-dilation. Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting. 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. INVAMED's Invaducer introducer sheath sets support the access step of peripheral interventions. Appropriate access selection helps reduce access-site complications. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. 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. INVAMED's Guardian protection device is designed for this distal-capture role. Access sheath sizing should match the planned devices to limit access-site complications. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist.
