What It Is
FDA-Cleared Indications
- Atherectomy in peripheral arteries affected by atherosclerotic disease.
- Removal of plaque from peripheral vascular lesions to improve blood flow.
- Use in peripheral vessels within the device's labeled size and anatomical ranges.
Clinical Applications
- Directional atherectomy of femoropopliteal artery lesions.
- Plaque removal during endovascular treatment of peripheral artery disease.
- Lesion preparation before or during balloon angioplasty or other peripheral interventions.
- Treatment of symptomatic peripheral arterial stenosis when plaque removal is clinically appropriate.

Practical Considerations
- The system is available in catheter configurations and sizes intended for specific peripheral vessel diameters; the operator must select the size specified in the current instructions for use.
- It is delivered through a vascular access sheath or guide catheter under fluoroscopic imaging, usually through femoral or other peripheral arterial access.
- The device is intended to remove excised plaque into its collection system; repeated passes may be required, and excessive manipulation can increase the risk of dissection, perforation or distal embolization.
- MRI safety depends on the specific system components and whether the device remains in the patient. The current manufacturer labeling should be checked before MRI; an atherectomy catheter is generally removed after the procedure.
- Important risks include bleeding at the access site, arterial dissection or perforation, thrombosis, distal embolization, infection, contrast reaction and kidney injury. Antiplatelet or anticoagulant treatment may be used according to the overall procedure and patient factors.
