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. Endovascular therapy aims to restore flow through the narrowed segment using balloons, stents, atherectomy, or a combination. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist.
Invaducer Intraducer (Introducer Sheath Sets): Overview
Introducer sheath sets representing the first step in vascular interventions, enabling secure and controlled entry into the arterial or venous system and designed to streamline angiographic procedures.
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
- 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.
- 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.
What is the regulatory status of these devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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.
Clinical and Technical Context
Use is guided by lesion morphology and clinician preference. 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. Atherectomy is often paired with embolic protection to capture dislodged debris. INVAMED's Extender paclitaxel drug-coated balloon is positioned for this drug-delivery role in peripheral vessels. Appropriate access selection helps reduce access-site complications. Drug dose and balloon sizing follow the device specifications and lesion characteristics. Covered stent grafts can be used to exclude certain lesions or manage complications. Device selection depends on lesion location, length, calcification, and clinical presentation, and is decided by the vascular specialist.

Lesion calcification is a major factor in choosing between plain angioplasty, atherectomy, drug delivery, and stenting. 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 TemREN atherectomy system is positioned for peripheral plaque modification. INVAMED's PTA balloon range is designed to cover common peripheral vessel sizes. Atherectomy removes or modifies plaque, which can be useful in heavily calcified lesions before ballooning or stenting. INVAMED's Atlas peripheral stent graft addresses covered-stent applications in the PAD portfolio. Balloon diameter and length are matched to the vessel to avoid over- or under-dilation.
