Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
