Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate acute and long term clinical and economic outcomes of endovascular procedures to treat Peripheral Arterial Disease (PAD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, observational, multi-center, clinical study examining predictors of clinical outcomes for patients undergoing endovascular treatment of lesions within or extending into the target area (10 cm above the medial epicondyle to the digital arteries). This includes disease in a vessel located within or extending into the distal superficial femoral artery (SFA), popliteal (POP), tibial peroneal trunk (TPT), anterior tibial (AT), posterior tibial (PT), and peroneal tibial (PR) arteries.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Subject's age ≥ 18 years.
2. Subject presents with a Rutherford classification of 2 to 6.
3. Subject presents with clinical evidence of PAD requiring endovascular intervention on one or both limbs that includes a target lesion in a native vessel located within or extending into 10 cm above the medial epicondyle to the digital arteries.

* If subject presents with bilateral disease, the first limb treated with a lesion in the target area will be considered the target limb.
* For subjects with one or more wounds on the target limb, the target lesion(s) should be considered the lesion(s) in the vessel(s) that provide(s) blood flow to the wound(s).
4. Subject has at least one lesion in a native vessel located within or extending into the target area that is crossed and treated with an endovascular device.

Exclusion Criteria

1. Subject is unwilling or unable to sign the IRB-approved informed consent form (ICF).
2. Subject is unable to understand or comply with the study protocol requirements.
3. Subject is currently participating in an investigational drug or other device study that can clinically interfere with the endpoints of this study.
4. Subject requires a conversion from endovascular intervention to a surgical bypass graft for any lesion(s) in the target area, as determined by the Investigator.
5. Subject has an in-stent restenosis in the target area, and this lesion is the only one requiring treatment.
6. Subject is pregnant or planning to become pregnant within the study period.
7. Subject has an anticipated life span of less than one (1) year.
