The primary objective of this research is to assess the agreement between INVU™ and IUPC (the gold standard) during prenatal monitoring of uterine contractions and to assess the safety of INVU™. Additional information comparing INVU™ to TOCO (the standard of care) was also collected.
This multi-center, prospective, comparative, open-label study will be performed in two steps: A training step where up to 40 subjects will be enrolled to confirm uterine contraction performance level. In the second, validation step, the performance of the uterine contraction detection algorithm will be validated. The validation phase will involve up to 80 subjects. Sub-study will be implemented in the sites that will monitor the uterine activity of the subjects with TOCO, in addition to INVU™ and IUPC. Following the screening process, participants subject will undergo continuous recording of the uterine contraction and the fetal heart rate (FHR) for 30 to 60 min using INVU™, Cardiotocograph ((TOCO / CTG), and Intrauterine Pressure Catheters (IUPC). The collected data will be downloaded and comprehensive analysis of the values will be performed offline. Each participant will undergo continuous monitoring by the medical team to identify any safety issue, including but not limited to irritation, sensitization, and potential harmful misuse.

The subject will undergo continuous recording of the uterine contractions and the fetal heart rate (FHR) for 30 to 60 min using INVU™.
The study participants will undergo continuous recording of the uterine contractions by IUPC.
Some of the study participants will undergo continuous recording of the uterine contractions and the fetal heart rate (FHR) by TOCO as well.

Assessment of the agreement between INVU™ and IUPC (the gold standard) during monitoring of uterine contractions as well as the agreement between Cardiotocography (TOCO) and IUPC, where applicable.
Three blinded assessors will review the uterine contractions output data (the recordings) from the monitoring devices and determine for each time point whether a contraction occurred. The assessors will not have visibility to the source of the recorded data. Each assessor will review the sessions in a randomized order, while the evaluation will include: a contraction start point, peak, and endpoint. The actual presence of a contraction will be determined by the IUPC.
Time frame: 30-60 minutes per participant
