This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating peripheral arterial disease (pad) devices. 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)
Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. 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.
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
- Access sheath sizing should match the planned devices to limit access-site complications.
- Embolic protection is often paired with atherectomy to capture dislodged debris.
- 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.
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
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 PTA balloon range is designed to cover common peripheral vessel sizes. 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. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. INVAMED's TemREN atherectomy system is positioned for peripheral plaque modification. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist. Embolic protection is often paired with atherectomy to capture dislodged debris. INVAMED's Guardian protection device is designed for this distal-capture role. Manufacturer figures reflect studied device performance, not guaranteed outcomes. 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. Use is guided by lesion morphology and clinician preference. INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. Access sheath sizing should match the planned devices to limit access-site complications. Drug dose and balloon sizing follow the device specifications and lesion characteristics.
