• Age 18-85 years old, male or female;

• The target lesion is located in the superficial femoral artery or the proximal popliteal artery;

• Peripheral arterial stenosis or occlusive disease with symptoms consistent with the Rutherford classification 2 to 5;

• Estimated life expectancy \>1 year;

• Subject has been informed of and understands the nature of the study and provides signed informed consent to participate in the study.

⁃ Angiographic Inclusion Criteria:

• Stenosis rate ≥70% under DSA by visual estimate, or 100% occluded lesion with a total lesion length less than 150mm (by visual estimate);

• Reference vessel diameter is between 3 mm and 7.5 mm, 50mm≤Total cumulative length of target lesions≤250mm; (In the case of bilimb lesions, a single target lesion with one limb meeting the protocol criteria is selected by the investigator; More than 2cm between lesions are considered as 2 lesions);

• After PTA treatment by DCB, there exists residual lesions, such as the target lesion has over 30% residual DS and/or presence of at least one post-PTA dissection (Type A-F) (by visual estimate);

• Patients with unobstructed inflow tract or successfully treated, visual residual stenosis ≤50%;

• Angiography showed at least one outflow tract was unobstructed at the distal end (Stenosis degree ≤70% before intervention).
