Who this trial is looking for
This trial is looking for adults with symptoms of lower limb artery disease. Participants will undergo a procedure using the Golazo® Peripheral Atherectomy System to improve blood flow in the legs.

8. Informed consent granted
Angiographic inclusion criteria:
9. Target lesion(s) defined as stenosis ≥70% by angiographic visual estimation
10. Total treated lesion length ≤20 cm by angiographic visual estimation
11. Target reference vessel diameter (RVD) ≥2.0 mm and ≤4.5 mm by angiographic visual estimation
12. Target limb will have a minimum of one patent (less than 50% stenosis) below the knee (BTK) vessel crossing the ankle, distal to any target lesion, providing perfusion to the foot at baseline
General exclusion criteria:
1. Active infection in the target limb
2. History of an endovascular procedure or open vascular surgery on the target limb within the last 30 days
3. Planned surgical or interventional procedure within 30 days after the index procedure
4. Lesion in the contralateral limb requiring intervention during the index procedure or within next 30 days
5. Critical limb ischemia (CLI) with Rutherford clinical classification category 6
6. Significant acute or chronic kidney disease with a GFR \<30 and/or requiring dialysis
7. Acute myocardial infarction (non-ST-elevation myocardial infarction or ST-segment elevation myocardial infarction) or other uncontrolled comorbidity in the opinion of the investigator
8. Myocardial infarction (MI) or stroke within two months of baseline evaluation
9. Pregnant or lactating
10. Subject is participating in another clinical investigation of a device, drug, or procedure that has not completed the study treatment or that clinically interferes with the endpoints of this study (post-approval registries are allowed as long as the investigator determines there is no clinical interference with study endpoints)
11. Contraindication to antiplatelet, anticoagulant, or thrombolytic therapy
12. Uncorrectable bleeding diathesis, platelet dysfunction, thrombocytopenia with platelet count \<125,000/microliter, known coagulopathy, or international normalized ratio (INR) \>1.5
13. Known allergy to contrast agents or medications used to perform endovascular intervention that cannot be adequately medicated
14. History of heparin-induced thrombocytopenia (HIT)
15. Any thrombolytic therapy within two weeks of enrollment
16. Target lesion(s) within a native vessel graft or synthetic graft
17. Significant stenosis or occlusion of inflow not successfully treated before the index procedure
18. Any evidence or history of intracranial or gastrointestinal bleeding or intracranial aneurysm
19. Vulnerable subject populations (e.g., incarcerated or cognitively challenged adults)
20. One or more of the following complications of the foot:
1. Osteomyelitis that extends to the metatarsal bones.
2. Gangrene involving the plantar skin of the forefoot, midfoot or heel
3. Deep ulcer or large shallow ulcer (\>3cm) involving the plantar skin of the forefoot, midfoot, or heel
4. Any heel ulcer with/without calcaneal involvement
5. Any wound with calcaneal bone involvement
6. Wounds that are deemed to be neuropathic or non-ischemic in nature
7. Wounds that require flap coverage or complete wound management for large soft tissue defect

Angiographic exclusion criteria:
22. More than 2 lesions to be treated with the investigational device; lesions located within 3 mm may be considered a single tandem lesion
