“Electrical Inhibition of Human Preterm Contractions”
The purpose of this study is to explore a new method to stop preterm uterine contractions using an electrical device. The device, an "electrical pacemaker for the uterus," has been approved by the Food and Drug Administration (FDA) for clinical research in pregnant women. The purpose of this study is to evaluate the feasibility and safety of the device. The investigators hypothesize that human preterm uterine contractions can be safely and objectively inhibited with a weak electrical current provided by an electrical inhibition (EI)/uterine pacemaker device, and that this effect relates to the timing and length of EI exposure.
Device - Electrical Uterine Pacemaker
The catheter is placed under ultrasound guidance into the posterior vaginal fornix next to the external cervical os. The electrode connectors are attached to the EI device. Activating the EI device involves: 1) turning the current pulse duration rotary dial clockwise to the desired setting; this is an important setting and should be set at 20ms; 2) turning the current frequency rotary dial clockwise to the desired setting; 3) turn on the EI device on with the on/off toggle switch; 4) SLOWLY turn ...read more on ClinicalTrials.org
