What is it indicated for?
The BirthTrack System is an ultrasound device intended to be
used for monitoring the active phase of labor in women with
term pregnancies, vertex presentation, and ruptured membranes.
It is intended to be placed when cervical dilation is between 3
cm and 7 cm. The device continuously measures cervical
dilation and fetal head station with ultrasound transducers:
attached to the maternal abdomen and cervix and to the fetal
scalp. These measurements are displayed numerically and
graphically as a function of time to show the progress of labor.
Indications for use as stated in the FDA summary.
