Outcome results
The Primary Effectiveness Endpoint is the Rate of Complete Closure of the Ductus Arteriosus at the Six-month Follow-up.
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.
Time frame: 180 days
Population: Of the 192 enrolled, 178 subjects experienced successful device placement.Of the 178 subjects with the device implanted,166 had a 6-month TTE and physical examination before 200 days post procedure or had an explant before the 6-month follow-up interval ended.
| Arm | Measure | Value (NUMBER) |

| Device | The Primary Effectiveness Endpoint is the Rate of Complete Closure of the Ductus Arteriosus at the Six-month Follow-up. | 98.19 percentage of participants |
The Primary Safety Endpoint is the Rate of Device and Procedure Related Serious Adverse Events (SAE) 180 Days Post Procedure.
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.
Time frame: 180 days
Population: Of the 192 enrolled subjects, 188 completed follow-up through 180 days post procedure;3 subjects were lost to follow-up (LTFU) before the 180-day interval and 1 subject was discontinued at the end of the 6-month visit without follow-up.
