Abstract

In certain variations, systems and/or methods for electromagnetic induction therapy are provided. One or more ergonomic or body contoured applicators may be included. The applicators include one or more conductive coils configured to generate an electromagnetic or magnetic field focused on a target nerve, muscle or other body tissues positioned in proximity to the coil. One or more sensors may be utilized to detect stimulation and to provide feedback about the efficacy of the applied electromagnetic induction therapy. A controller may be adjustable to vary a current through a coil to adjust the magnetic field focused upon the target nerve, muscle or other body tissues based on the feedback provide by a sensor or by a patient. In certain systems or methods, pulsed magnetic fields may be intermittently applied to a target nerve, muscle or tissue without causing habituation.

Claims

1. A method, comprising:

applying an electrode patch to skin in proximity to a stimulation site of a patient such that the electrode patch is disposed on an outer surface of the skin and the electrode patch is electrically coupled with a controller unit, the controller unit including a pulse generator;

electrically coupling a percutaneous electrode having an end for inserting in proximity to a tibial nerve of the patient to the controller unit;

inserting the end of the percutaneous electrode into the skin in proximity to the tibial nerve of the patient; and

activating the pulse generator such that current pulses flow along the tibial nerve by passing between the electrode patch and the percutaneous electrode, the current pulses configured to treat incontinence.

3. The method of claim 1, wherein the electrode patch is placed on an ankle of the patient.

4. The method of claim 1, wherein the controller unit communicates wirelessly with the electrode patch.

5. The method of claim 1, wherein the controller unit communicates wirelessly with the percutaneous electrode.

2. A method, comprising:

positioning a transcutaneous electrode on skin of a patient in proximity to a tibial nerve;

inserting an end of a percutaneous needle electrode through the skin in proximity to the tibial nerve, the percutaneous needle electrode including a wire disposed opposite the end;

securing a controller unit to the transcutaneous electrode such that the controller unit is electrically coupled to the transcutaneous electrode, the controller unit including a pulse generator;

connecting the wire of the percutaneous needle electrode to the controller unit for electrically coupling the percutaneous needle electrode to the controller; and

activating the pulse generator such that current pulses flow along the tibial nerve by passing between the transcutaneous electrode and the percutaneous needle electrode, the current pulses configured to treat incontinence.

6. The method of claim 2, wherein the transcutaneous electrode is placed on an ankle of the patient.

7. The method of claim 2, wherein the controller unit communicates wirelessly with the transcutaneous electrode.

8. The method of claim 2, wherein the controller unit communicates wirelessly with the percutaneous needle electrode.
