Evaluation of the MAGNITUDE® Bioresorbable Drug-Eluting Scaffold in the Treatment of Patients With Below the Knee Disease in Australia

7.1.1 General Inclusion Criteria 1. Subject (or their legally authorized representative) has provided written informed consent prior to any study-related procedure, using the form approved by the Human Research Ethics Committee. 2. Subject agrees not to participate in any other investigational device or drug study for a period of at least 12 months following the index procedure. Note: Questionnaire-based studies, or other studies that are non-invasive and do not require investigational devices or medications are allowed. 3. Subject has symptomatic chronic limb-threatening ischemia, determined as Rutherford categories 4 or 5. 4. Subject is ≥ 18 years and ≤ 90 years of age. 5. Subject agrees to complete all protocol-required follow-up visits, including angiograms. 7.1.2 Angiographic Inclusion Criteria 6. Target lesion(s) in the infrapopliteal vessel(s) of the same limb located in any of the following vessels: tibioperoneal trunk (TPT), anterior tibial artery (ATA), posterior tibial artery (PTA), or peroneal artery. 7. Target lesion(s) must be located in the proximal 2/3 of the native infrapopliteal vessels and at least 10 cm above the tibio-talar joint. 8. Up to two (2) target lesions and two different arteries can be treated, where all target lesions must be successfully crossed with a guidewire prior to randomization. Note: For CTO, retrograde crossing of the lesion is allowed but treatment must be via antegrade. Note: The most distal lesion should be treated before treating more proximal lesions. 9. Distal tibial and pedal runoff for each target lesion must be patent (free of lesions with \< 50% stenosis). If the index vessel is either anterior or posterior tibial artery, outflow must be contiguous with a patent dorsalis pedis or common plantar artery. 10. Inflow above-the-knee lesions must be treated successfully (\< 30% diameter residual stenosis by angiography without evidence of distal embolization, thrombus formation, or vessel rupture). Presence of hemodynamically significant lesions (\>50% stenosis) in the P3 segment of the popliteal artery (infrageniculate) is an exclusion criterion. Note: Inflow lesions may be treated during the index procedure prior to target lesion(s) using the standard of care (including drug-eluting devices), without wiring the target lesion, if possible. Treatment of inflow lesions in the target limb within prior 30 days is also allowed provided the treatment was successful. Note: Atherectomy of non-target lesions is not allowed. 11. Target lesion must have reference vessel diameter is between 3.0 - 3.5 mm by angiography. Vessel size measured by IVUS is highly recommended to verify RVD. 12. Target lesion(s) is de novo or restenosed ≥ 70% stenosed by angiography. Note: In-stent restenosis is an exclusion criterion. 13. The total target lesion length among all target lesions must not exceed 11 cm. 14. Minimum target lesion length must be \>14 mm. 15. Total scaffold length must not exceed 12 cm, and include at least 2 mm of normal vessel from each pre-dilatation border. 16. The target vessel must not have any other angiographic significant non-target lesions (≥ 50%). 17. Tandem non-contiguous target lesions are allowed if there is a plaque-free zone of ≥ 2 cm between the lesions. Total lesion lengths must not exceed 11 cm. 18. Target lesion(s) stenting does not block access to patent main named branches (tibioperoneal trunk (TPT), anterior tibial artery (ATA), posterior tibial artery (PTA), or peroneal artery). 19. Non-target below-the-knee lesions in non-target vessels must be successfully treated per standard of care prior to randomization without evidence of thrombosis, distal embolization, or vessel rupture. Note: Drug-eluting and atherectomy devices for treatment of non-target lesions is not allowed. 20. Subject has suitable common femoral (contralateral or antegrade ipsilateral) vascular access. Note: Retrograde pedal approach is allowed for crossing but not for treatment of target lesion(s). 21. At least one fully patent below-the-ankle artery (i.e., dorsalis pedis; common with either, lateral, or medial plantar arteries) without hemodynamically significant lesions (≥ 50% diameter stenosis by angiography) must be present in the target limb. 7.2 Exclusion Criteria 7.2.1 General Exclusion Criteria Subjects must not meet any of the following general and angiographic exclusion criteria: 1. Subject with Body Mass Index (BMI) \< 18. 2. Subject is pregnant or nursing. Subjects who plan pregnancy during the clinical investigation follow-up period may not be enrolled. Note: Subjects of child-bearing potential must have a negative pregnancy test ≤ 28 days prior to the index procedure and agree to use contraception for 6 months. 3. Estimated life expectancy \<1 year, in the opinion of the Investigator at the time of enrollment. 4. Subject is permanently bedridden. 5. Subject has known hypersensitivity or contraindication to device materials and their degradants (sirolimus, poly (L-lactide), poly (D, L-lactide), lactic acid, or platinum-iridium) or to study medications (including antiplatelet medications) or to contrast media and who cannot be adequately premedicated. 6. Subject has planned surgery or procedure necessitating discontinuation of antiplatelet medications within 6 months after the index procedure. 7. Subject has had revascularization procedure within the target vessel in the previous 3 months 8. Subject has prior major amputation involving the target limb. Note: Major amputation of the contralateral limb is allowed. 9. Subject has planned surgical or endovascular procedure within 6 months following the index procedure. Note: A planned minor amputation (toe and/or transmetatarsal amputation in either limb) is allowed. Treatment of inflow lesions in the target limb within prior 30 days is also allowed provided the treatment was successful (\< 30% residual stenosis, no thrombi, distal emboli or vessel ruptu
