Non-invasive nerve stimulation with mobile device
Devices, systems and methods are disclosed that allow a patient to self-treat a medical condition, such as headache, by noninvasive stimulation of a nerve. A system comprises a stimulator having an interface configured to contact an outer skin surface of a patient and an energy source coupled to the interface. The energy source transmits an electrical impulse through the interface transcutaneously through the outer skin surface of the patient to a nerve of the patient such that the nerve is modulated. The system further comprises a mobile device coupled to the stimulator to transmit data to the stimulator. The data includes a therapy regimen to reduce one or more symptoms of a headache in the patient.
1. A system comprising:
a stimulator having an interface configured to contact an outer skin surface of a patient;
an energy source coupled to the interface, wherein the energy source transmits an electrical signal comprising a plurality of electrical impulses through the interface transcutaneously through the outer skin surface of the patient to a nerve of the patient such that the nerve is modulated, wherein the electrical impulses have a frequency of 1 kHz to 20 kHZ; and
a downloadable software application downloadable onto a mobile phone configured for wirelessly coupling to the stimulator to transmit data to the stimulator, wherein the data includes a therapy regimen to reduce one or more symptoms of a headache in the patient, wherein the downloadable software application controls a duration of time in which the stimulator generates the electrical signal, wherein the duration of time is 5 minutes to 30 minutes.
2. The system of claim 1 , wherein the mobile phone comprises a user interface that permits the patient to modulate an amplitude of the electrical impulses.
3. The system of claim 1 , wherein the stimulator comprises a housing, wherein the energy source is disposed within the housing.
4. The system of claim 1 , wherein the interface comprises an electrode.
5. The system of claim 1 , wherein the energy source includes a rechargeable battery.
6. The system of claim 1 , wherein the electrical impulses includes bursts of 2 to 20 pulses with each burst having a frequency of about 1 burst per second to about 100 bursts per second, wherein each of the pulses has a duration of about 50 microseconds to about 1000 microseconds.
7. The system of claim 1 , wherein the mobile phone is coupled to a computer comprising a database including at least one of medical records for the patient or billing account information for the patient.
8. The system of claim 7 , wherein the medical records include data representing at least one of an amount of energy to transfer from the mobile device to a handheld device, a number of pulses per burst, a duration of a pulse, the duration of time, an amplitude of an electric field, a wait-time between stimulation sessions, a movement distance, a left-side versus right-side indicator, or a headache level.
9. The system of claim 1 , wherein the nerve is a vagus nerve, and the outer skin surface is on a neck of the patient.
10. A method for treating a headache in a patient comprising:
downloading a software application onto a mobile phone;
communicating data from the software application for an electrical stimulation therapy wirelessly to a stimulator;
positioning an interface of the stimulator against an outer skin surface of a patient;
generating an electrical signal comprising a plurality of electrical impulses within the stimulator, wherein the electrical impulses have a frequency of 1 kHz to 20 kHz;
transmitting the electrical impulses through the interface and transcutaneously through the outer skin surface to a nerve at a target region within the patient such that the nerve is modulated, and one or more symptoms of the headache are reduced; and
transmitting dosing information wirelessly to the stimulator, wherein the dosing information includes a duration of time of 5 minutes to 30 minutes in which the stimulator generates the electrical signal; and
controlling the stimulator with the software application such that the stimulator transmits the electrical impulse for the duration of time.
11. The method of claim 10 , further comprising communicating data from a remote source over to software application and wirelessly coupling the mobile phone to the stimulator in order to transmit the data to the stimulator.
12. The method of claim 11 further comprising transferring energy from the mobile phone to the stimulator.
13. The method of claim 10 , further comprising communicating authorization to the stimulator in order to enable the stimulator to operate.
14. The method of claim 10 , further comprising wirelessly transmitting information regarding the electrical impulses to the stimulator.
15. The method of claim 14 , wherein the information includes an amplitude of the electrical impulses.
16. The method of claim 10 , wherein the nerve is a vagus nerve, and the outer skin surface is on a neck of the patient.
