Uterine electrical stimulation system and method
Systems and methods for applying stimulating current to a patient for treating insufficient uterine contractions are provided. The system includes stimulation electrodes of a balloon electrode array device, a ring electrode array device, an electrode probe device, or a mesh electrode array device. Some aspects of the invention also provide a connector and cable device for coupling the stimulation electrodes to electronics for generating and providing the stimulating current to the stimulation electrodes.
1. A system configured to apply stimulating current to a patient for treating insufficient uterine contractions, the system comprising:
a balloon electrode array device configured to be coupled to one of a uterus, a cervix, a vaginal wall, and an abdominal wall of the patient to provide the stimulating current to the patient, the balloon electrode array device including
at least one balloon;
an access tube extending into the at least one balloon;
a plurality of lead wires routed through the access tube and into an inside portion of the balloon;
a plurality of electrodes, each one of the plurality of electrodes coupled to one of the plurality of lead wires, the plurality of electrodes extending from the inside portion of the balloon to an outer surface of the balloon; and
a current source coupled to the plurality of lead wires and configured to control the operation of the electrodes to apply the stimulating current to the patient for treating insufficient uterine contractions.
2. The system as recited in claim 1 further comprising a core extending into the inside portion of the balloon.
3. The system as recited in claim 2 in which the core comprises a semi-rigid material.
4. The system as recited in claim 1 in which the at least one balloon is constructed of at least one of latex, rubber, silicone, and a biocompatible stretchable polymer.
5. The system as recited in claim 1 in which the at least one balloon is inflatable via an inflating material introduced through the access tube.
6. The system as recited in claim 1 in which the at least one balloon includes an outer balloon and an inner balloon.
7. The system as recited in claim 1 in which a conductive portion of each of the plurality of electrodes extends from the inside portion of the balloon to the outer surface of the balloon.
8. The system as recited in claim 1 further comprising a drainage tube.
9. The system as recited in claim 1 wherein the plurality of electrodes are coated with and used to administer a medication.
