Primary Outcome Measures:
  • The Primary Safety Endpoint is the Rate of Device and Procedure Related Serious Adverse Events (SAE) 180 Days Post Procedure. [ Time Frame: 180 days ]

    The primary safety endpoint is the rate of device and/or procedure related SAEs reported in subjects whom device placement is attempted from the procedure through 180 days post procedure

    SAEs are defined as: Adverse events resulting in the following; death, life-threatening adverse event, inpatient hospitalization or prolongation of existing hospital stay, persistent or significant disability/incapacity or medically significant event.

  • The Primary Effectiveness Endpoint is the Rate of Complete Closure of the Ductus Arteriosus at the Six-month Follow-up. [ Time Frame: 180 days ]
    The primary efficacy endpoint is the rate of complete closure of the ductus arteriosus as assessed by the absence of residual flow and continuous murmur at the six-month follow-up by transthoracic echocardiography and physical exam respectively.

Enrollment: 192
