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 system configured to apply stimulating current to a patient for treating insufficient uterine contractions, the e system comprising:

a mesh electrode array device configured to be coupled to a uterus of the patient to provide stimulating current to the patient, the mesh electrode array device including;

a non-conductive mesh material including a plurality of segments and a plurality of nodes formed at locations where one or more of the plurality of segments intersect;

a plurality of electrodes, wherein each one of the plurality of electrodes are coupled to a corresponding one of the plurality of nodes;

a plurality of lead wires, wherein each one of the plurality of lead wires are insulated and are coupled to one of the plurality of electrodes; and

a current source coupled to the plurality of lead wires and configured to control operation of the plurality of electrodes to apply the simulating current to the patient for treating insufficient uterine contractions.

2. The system as recited in claim 1 wherein the non-conductive mesh material is constructed of one of silicone, latex, rubber, plastic, and nylon.

3. The system as recited in claim 1 wherein the non-conductive mesh material is expandable in order to one of cover, envelope, and encircle the uterus of the patient when deployed in the uterus to apply the stimulating current to the patient.

4. The system as recited in claim 1 wherein the plurality of electrodes each include a conductive tip and a non-conductive housing, and wherein the plurality of electrodes are positioned along one of the plurality of nodes so that the conductive tips contact uterine tissue when the mesh electrode array device is deployed in the uterus of the patient to apply the stimulating current to the patient.

5. The system as recited in claim 4 wherein each of the plurality of lead wires pass through one of passages, gaps, grooves, and ridges of the housings to electrically connect to the tips.

6. The system as recited in claim 1 wherein the plurality of electrodes are coated with and used to administer a medication.
