Abstract: Systems, devices, and methods are provided that control, support, and/or elongate a cervix to treat pregnancy complications and/or delay an onset of labor so that a gestational period for a fetus may be extended, thereby preventing preterm labor and delivery of the fetus. The cervical control systems may include a main body configured for placement in a vagina. The main body has in internal passageway configured for acceptance of a cervix therein and an inflatable and/or expandable inner cuff extends from portion of the internal passageway. The inner cuff may be expandable inward toward the cervix, or downward away from the uterus, or both inward and downward so that the inner cuff may engage, or grip, the cervix thereby holding the cervical control system in place while compressing the cervix closed, elongating the cervix, and/or adjusting an angle of orientation of the cervix.
