The hypothesis is that the new vacuum assisted delivery device iCup is more effective than the reference cup, in terms of maternal and newborn morbidities and functioning
Currently, instrumental extractions are used in about 10% to 15% of the 860 000 annual deliveries in France and the use of vacuum extractors increases from year to year. In addition to sterilizable vacuum extractors several different types of vacuum extractor have been developed, in particular the single use Kiwi cup or the so-called 'soft' cup extractors. However, studies evaluating these new cups have not shown their superiority in comparison to the conventional metallic vacuum extractor. Accordingly, it is legitimate to assess the new vacuum extractor iCup, an innovative "mix" of metallic cup and 'soft' cups that should combine the advantages of both; and to compare the iCup vacuum extractor with the sterilizable metallic cup extractor, the most effective vacuum extractors available to date.

maternal lesions: cervix lesions, postpartum haemorrhage
Time frame: 28 days maximum
neonatal lesions: minor scalp injuries, Apgar score < 7, pH < 7.20, anaemia, jaundice, transfer
Time frame: 28 days maximum
medico-economic criteria: cost-effectiveness analysis of the studied medical devices
Time frame: 28 days maximum
