Further study details as provided by Occlutech International AB:

Primary Outcome Measures:
  • Successful closure of patent ductus arterious without evidence of any complication assessed by echocardiongram, ECG and X-ray 30 and 90 days after implant. [ Time Frame: 3 months ]

Secondary Outcome Measures:
  • Successful closure without evidence of residual shunt after 1 year confirmed by echocariodgram. Safety: freedom of major adverse events i.e periherial embolism or endocarditits. [ Time Frame: 30, 90, 180 and 360 days after implant ]
