Abstract

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.

Claims

1. A balloon electrode array device configured to apply stimulating current to a patient for treating insufficient uterine contractions, the balloon electrode array device comprising:

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; and

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.

2. The balloon electrode array device as recited in claim 1 further comprising a core extending into the inside portion of the balloon.

3. The balloon electrode array device as recited in claim 2 in which the core comprises a semi-rigid material.

4. The balloon electrode array device 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 balloon electrode array device 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 balloon electrode array device as recited in claim 1 in which the at least one balloon includes an outer balloon and an inner balloon.

7. The balloon electrode array device 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 balloon electrode array device as recited in claim 1 further comprising a drainage tube.

9. The balloon electrode array device as recited in claim 1 wherein the plurality of electrodes are coated with and used to administer a medication.

25. A method for treating insufficient uterine contractions after labor and delivery, the method comprising:

generating electrical stimulating current signals at a frequency between about 5.0 Hertz and about 100 Hertz; and

applying the electrical stimulating current signals to one of a cervix, a vagina, and a uterus using one of a balloon electrode array device, a mesh electrode array device, an electrode probe device, and a ring electrode array device to produce uterine tonic contractions.

26. 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;

a current source controlled by the control module to produce stimulating current at a frequency between about 5.0 Hertz and about 100 Hertz;

one of a balloon electrode array device, a mesh electrode array device, an electrode probe device, and a ring electrode array device 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 in order for the patient to produce tonic uterine contractions.
