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)
Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination.
TemREN Peripheral Atherectomy System: Overview
Rotational atherectomy system for debulking heavily calcified peripheral arterial lesions that resist balloon dilatation; the high-speed burr removes hard plaque as vessel preparation before stenting or drug-coated balloon therapy.
How It Works and Where It Fits
INVAMED's PAD portfolio spans access, plaque modification, angioplasty, drug delivery, stenting, and embolic protection. Peripheral stents scaffold an artery open after angioplasty when the vessel recoils or dissects, maintaining the widened lumen. A drug-coated balloon delivers an antiproliferative drug — commonly paclitaxel — to the artery wall during inflation to reduce the risk of restenosis.
Key Considerations
- 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.
- Access sheath sizing should match the planned devices to limit access-site complications.
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.
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.
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
Femoropopliteal segments favor flexible self-expanding devices because of repeated flexion. INVAMED PAD devices are for use by trained vascular specialists per the IFU and local approvals. Use is guided by lesion morphology and clinician preference. Symptoms range from exertional leg pain (claudication) to, in severe cases, rest pain and non-healing wounds known as critical limb ischemia. Atherectomy is often paired with embolic protection to capture dislodged debris. Covered stent grafts can be used to exclude certain lesions or manage complications. INVAMED's TemREN atherectomy system is positioned for peripheral plaque modification. INVAMED's PTA balloon range is designed to cover common peripheral vessel sizes. Manufacturer figures reflect studied device performance, not guaranteed outcomes. Access sheath sizing should match the planned devices to limit 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. 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. Embolic protection is often paired with atherectomy to capture dislodged debris. INVAMED's Guardian protection device is designed for this distal-capture role. 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. Drug dose and balloon sizing follow the device specifications and lesion characteristics.
