Claim:
1. A system for treating insufficient uterine contractions in a patient after labor and delivery, the system comprising: a control module which performs at least one of preprogrammed stimulation tasks and user-defined stimulation tasks including a combination of parameters configured to produce tonic uterine contractions, wherein pre-recorded uterine electrical traces obtained from normal contracting patients after labor and delivery are saved digitally within memory of the control module; a current source controlled by the control module to produce biphasic, sinusoidal, tonic uterine muscle contraction stimulating current at a frequency greater than 5.0 Hertz with patterns identical to the pre-recorded uterine electrical traces; one or more stimulation electrodes coupled to one of a uterus, a cervix, a vaginal wall, and an abdominal wall of the patient; and wherein the control module is configured to control the current source to deliver stimulating current to the one or more electrodes during uterine atony after labor and delivery to provide the stimulating current to the patient in order for the patient to produce tonic uterine contractions that are initiated by the stimulating current and are global uterine contractions sustained for a time period after the stimulating current has been stopped.
