Peripheral Artery Disease

Brief summary

All-comers, prospective, multi-center, single-arm, non-interventional post market clinical follow-up (PMCF) Cohort 1 - Claudicants: Rutherford Clinical Category (RCC) 2-3 Cohort 2 - Critical Limb Ischemia: Rutherford Clinical Category (RCC) 4-6

Detailed description

To prospectively collect and assess safety and efficacy data on the AcoArt drug-coated PTA balloon catheters carrying the CE Mark per current Instructions for Use in a real-world cohort of patients with symptomatic arterial disease undergoing endovascular lower limb revascularization per the institution's standard practice.

Interventions

DEVICEAcoArt Orchid (0.035), AcoArt Tulip (0.018) and AcoArt Litos (0.014) percutaneous transluminal angioplasty (PTA) paclitaxel drug coated balloon catheter manufactured by Acotec Scientific Co., Ltd.

Inclusion criteria

* 1\. Patient is ≥ 18 years old at the time of consent. * 2\. Significant stenosis (≥70%) or occlusions of de-novo or restenotic lesion(s) located in iliac, superficial femoral, popliteal and/or infra-popliteal arteries suitable for angioplasty per operator visual assessment. * 3\. Lesion(s) can be treated with available AcoArt Orchid (0.035), AcoArt Tulip (0.018) and AcoArt Litos (0.014) DCB device per current IFU. * 4\. Subject has provided written informed consent prior to participation in the PMCF, understands the purpose of this PMCF and agrees to comply with all protocol-specified examinations and follow-up appointments. * 5\. Rutherford Classification Category 2-6 Subjects with Rutherford Category 2 have gone through a conservative therapy without success. * 6\. Inflow lesion treated prior to target lesion treatment

Exclusion criteria

* 1\. Rutherford Classification Category 0, 1 * 2\. Patient already enrolled in other investigational (interventional) studies that would interfere with study endpoints * 3\. Inability to tolerate required antithrombotic or antiplatelet therapies. * 4\. Non-dilatable severely calcified lesion. * 5\. Known hypersensitivity/allergy to components of the investigational device * 6\. Un-treated acute or subacute thrombus in the target lesion. * 7\. Life expectancy \< 1 year. * 8\. Pregnancy or female patient with child bearing potential not taking adequate contraceptives or currently lactating. * 9\. Other comorbidities, which in the opinion of the investigator limit longevity or likelihood of compliance with protocol follow up. * 10\. Myocardial infarction or stroke within 30 days prior to index procedure.

Design outcomes

Primary

MeasureTime frameDescription
Primary safety endpoint- CLI group12 MonthsA composite of freedom from device- and procedure-related mortality, freedom from major target limb amputation and TLR within 12 months post-index procedure
Primary safety endpoint- non-CLI group30 daysA composite of freedom from major adverse limb events and perioperative death (MALE-POD) through 30 days after index procedure. A major adverse limb event is defined as above-ankle amputation or major reintervention (ie, new bypass graft, major surgical graft revision such as a jump graft or an interposition graft, or thrombectomy/thrombolysis) of the treated limb.
Primary efficacy endpoint - non-CLI group12 MonthsFreedom from clinically-driven target lesion revascularization (CD-TLR) within 12 months after index procedure, which is defined as any re-intervention within the target lesion(s) due to recurrent clinical symptoms of PAD (increase of one Rutherford class or more) and/or drop of ankle-brachial index (≥20% or \>0.15 when compared with maximum early post-procedural level).
Primary efficacy endpoint -CLI group6 MonthsFreedom from clinically-driven TLR within 6 months after index procedure, which is defined as any re-intervention within the target lesion(s) due to delayed or worsening wound healing, new or recurrent wound, or worsening Rutherford class.
