Abstract

An energy emitting apparatus for providing a medical therapy includes one or more energy generators, a logic controller electrically connected to the one or more energy generators, and one or more sensors for detecting electric conduction in a target nerve that are connected to the logic controller. The one or more energy generators produce energy focused on the target nerve upon receiving a signal from the logic controller, and the energy is varied by the logic controller according to an input provided by the one or more sensors. In one embodiment, the energy emitting apparatus is an apparatus for magnetic induction therapy that includes one or more conductive coils disposed in an ergonomic housing that produce a magnetic field focused on the target nerve upon receiving an electric current from the logic controller based on an input provided by the one or more sensors.

Claims

1. A method of controlling magnetic induction therapy in the treatment of overactive bladder, comprising:

positioning a first portion of a patient'"'"'s body relative to a housing such that a posterior tibial nerve within the first portion of the body is in proximity to at least one conductive coil disposed within or along the housing wherein the housing is positioned external to the patient;

increasing a current through the at least one coil to generate a magnetic field and to deliver the magnetic field to the posterior tibial nerve until conduction through the nerve is detected wherein the magnetic field stimulates the posterior tibial nerve; and

adjusting the current via a controller in communication with the at least one conductive coil based on the detected conduction to control the therapy for treating overactive bladder.

2. The method of claim 1 wherein positioning a first portion of a patient'"'"'s body comprises placing an ankle leg relative to the housing.

3. The method of claim 1 wherein increasing a current comprises passing the current through a plurality of coils to generate the magnetic field.

4. The method of claim 1 wherein increasing a current further comprises detecting the conduction through the nerve along a second portion of the body in proximity to the nerve.

5. The method of claim 1 wherein the conduction is detected through the nerve by the patient.

6. The method of claim 1 wherein adjusting the current via the controller comprises actuating a patient-operated control to adjust the current through the at least one coil.

7. The method of claim 1, wherein current is increased through the at least one coil to generate a magnetic field focused on the nerve until a signal indicating that an afferent nerve of the nerve has been stimulated is detected.

8. A method of controlling magnetic induction therapy in the treatment of overactive bladder, comprising:

positioning a first portion of a patient'"'"'s body relative to a housing such that a posterior tibial nerve within the first portion of the body is in proximity to at least one conductive coil disposed within or along the housing wherein the housing is positioned external to the patient;

increasing a current through the at least one coil to generate a magnetic field and to deliver the magnetic field to the posterior tibial nerve until conduction through the nerve is detected by the patient wherein the magnetic field stimulates the posterior tibial nerve; and

actuating a patient-operated controller in communication with the at least one conductive coil to adjust the current based on the detected conduction to control the therapy for treating overactive bladder.

9. The method of claim 8 wherein positioning a first portion of a patient'"'"'s body comprises placing an ankle relative to the housing.

10. The method of claim 8 wherein increasing a current comprises passing the current through a plurality of coils to generate the magnetic field.

11. The method of claim 8 wherein increasing a current comprises further detecting conduction through the nerve via at least one sensor in proximity to the nerve and which is in communication with the controller.

12. The method of claim 8 wherein increasing a current comprises increasing the current until paresthesia is detected by the patient.

13. The method of claim 12 wherein actuating a patient-operated controller comprises having the patient reduce the current until the paresthesia is undetectable by the patient.

14. The method of claim 13 further comprising maintaining the current for a predetermined period of time.

15. The method of claim 8, wherein current is increased through the at least one coil to generate a magnetic field focused on the nerve until a signal indicating that an afferent nerve of the nerve has been stimulated is detected.
