Brief Summary
The ADO II AS Study is a single arm, prospective, multicenter, nonrandomized clinical investigation to characterize the safety and effectiveness of the ADO II AS device in patients with a patent ductus arteriosus (PDA). Subjects will be implanted with the ADO II AS device using a transcatheter femoral vessel approach under fluoroscopic and echocardiographic guidance. To account for subject dropout, up to 50 subjects will be enrolled in this clinical investigation. Up to an additional 150 subjects may be enrolled under continued access. The clinical investigation will be conducted at up to 10 centers in the United States. Subjects participating in this clinical investigation will be followed for 3 years. The expected duration of enrollment is 18 months. The total duration of the clinical investigation is expected to be 4.5 years.

Outcome Measures
Primary Outcomes (2)
Safety Endpoint: The Rate of Major Complications After an Attempted ADO II AS Device Implant
Major complications are defined as device (ADO II AS) or procedure-related adverse events resulting in any of the following: * death, * life-threatening adverse event, * persistent or significant disability/incapacity, and/or * a major open surgical intervention which is performed by a surgeon under general anesthesia
Through 180 days
Effectiveness Endpoint: The Rate of Effective Closure of the Ductus Arteriosus Among Subjects With a Successful ADO II AS Implant
The primary effectiveness endpoint is the rate of effective closure of the ductus arteriosus among subjects with a successful ADO II AS implant as assessed by the presence of either a Grade 0 (none) or Grade 1 (trivial) shunt at the 6-month follow-up by transthoracic echocardiography (TTE).
At the 6-month follow-up
Secondary Outcomes (1)
The Rate of Significant Obstruction of the Pulmonary Artery or Aorta
Through 6 month follow-up visit
Study Arms (1)
PDA closure
EXPERIMENTALInterventions
Closure of PDA using Amplatzer Duct Occluder II Additional Sizes (ADO II AS).
Eligibility Criteria
You may qualify if:
- Diagnosis of a PDA
- PDA ≤ 4mm in diameter
- PDA ≥ 3mm in length
- Subject (or legally authorized representative) is willing to comply with all pre-procedure, post-procedure, and follow-up testing requirements and provides consent to participate in the clinical study
- NOTE: This study is enrolling children and all local laws and governing IRB requirements will be followed for obtaining informed consent
You may not qualify if:
- Weight \< 700 grams at time of the procedure
- Age \< 3 days at time of procedure
- Coarctation of the aorta
- Left pulmonary artery stenosis
- Cardiac output that is dependent on right to left shunt through the patent ductus arteriosus due to pulmonary hypertension
- Intracardiac thrombus
- Active infection requiring treatment at the time of implant
- Female subjects of child bearing potential are either pregnant or desire to become pregnant within six months post implant
- Other disease process likely to limit survival to less than six (6) months
- Participating in another study for an investigational drug and/or device that may clinically interfere with this study's endpoints
