The pressure sensor of a Corometrics 259CX Series Maternal/Fetal Monitor was connected to a Koala IPC 5000 Intrauterine Pressure System to document intraluminal pressure. The cut tip of the catheter was inserted into the first port of a four-way stopcock. The second port of the stopcock was attached via a Luer lock to the syringes that were used to infuse water into the balloons. The third Luer lock of the stopcock was attached to the infusion port of the balloons.
