Described herein are methods, devices and system for selecting an optimum position of a stimulation electrode, and particularly methods, devices and systems for optimizing the position of a stimulation electrode for stimulating the inflammatory reflex and thereby inhibiting inflammation. The methods
Described herein are methods, devices and system for selecting an optimum position of a stimulation electrode, and particularly methods, devices and systems for optimizing the position of a stimulation electrode for stimulating the inflammatory reflex and thereby inhibiting inflammation. The methods, devices and systems described herein may generally include the analysis of one or more artifact modalities arising after the application of a stimulation pulse. One or more of these artifact modalities (e.g., EMG, ECG, etc.) may be detected and used to generate a comparable indicator of the fitness of the position of the electrode relative to a target, such as a portion of the inflammatory reflex like the vagus nerve.

1. A method of optimizing the position of an electrode relative to a subject's inflammatory reflex, the method comprising: implanting an electrode in electrical communication with either the vagus nerve, the splenic nerve, the hepatic nerve or the trigeminal nerve so the electrode can be stimulated
1. A method of optimizing the position of an electrode relative to a subject's inflammatory reflex, the method comprising: implanting an electrode in electrical communication with either the vagus nerve, the splenic nerve, the hepatic nerve or the trigeminal nerve so the electrode can be stimulated to inhibit inflammation:applying an electrical stimulus to electrode;detecting a stimulation artifact;determining an indicator of the power of the stimulation artifact, wherein the step of determining an indicator of the power of the stimulation artifact includes calculating the power of the stimulation artifact and a second stimulation artifact; andadjusting the position of the stimulation electrode based on the indicator of the power of the stimulation artifact. 2. The method of claim 1, wherein the step of detecting the stimulation artifact comprises detecting the stimulation artifact between the applied stimulation. 3. The method of claim 1, wherein the stimulation artifact is selected from the group consisting of: EMG, EKG, and evoked potentials. 4. The method of claim 1, further comprising detecting a second stimulation artifact. 5. The method of claim 1, further comprising displaying an indicator of the power of the stimulation artifact. 6. The method of claim 1, wherein the step of implanting the electrode comprises implanting a probe having a plurality of electrodes thereon. 7. The method of claim 1, further comprising applying an electrical stimulus to a second electrode and detecting a second stimulation artifact associated with the stimulus from the second electrode; further comprising determining an indicator of the power of the second stimulation artifact. 8. The method of claim 1, further comprising measuring one or more indicators of inflammation. 9. The method of claim 8, further comprising determining a level of inhibition of inflammation based on the measurement of one or more indicators of inflammation. 10. The method of claim 8, further comprising adjusting the position of the stimulation electrode based on the measurement of one or more indicators of inflammation. 11. The method of claim 8, wherein the one or more indicators of inflammation is the level of a biomarker. 12. The method of claim 11, wherein the biomarker is CD11. 13. The method of claim 8, wherein the one or more indicators of inflammation is the level of a neurotransmitter. 14. The method of claim 13, wherein the neurotransmitter is acetylcholine. 15. The method of claim 8, wherein the one or more indicators of inflammation is body temperature. 16. The method of claim 8, wherein the one or more indicators of inflammation is the distribution of cell types. 17. The method of claim 16, wherein the distribution of cell types include granulocyte distribution. 18. A method of optimizing the position of an electrode relative to a subject's inflammatory reflex, the method comprising: implanting an electrode in electrical communication with either the vagus nerve, the splenic nerve, the hepatic nerve or the trigeminal nerve so the electrode can be stimulated to inhibit inflammation:applying an electrical stimulus to electrode;detecting a stimulation artifact;determining an indicator of the power of the stimulation artifact;adjusting the position of the stimulation electrode based on the indicator of the power of the stimulation artifact; andrepeating the steps of applying an electrical stimulus to the electrode and detecting the stimulation artifact; further wherein the step of determining the indicator of the power of the stimulation artifact comprises averaging the detected stimulation artifacts to determine the indicator of the power of the stimulation artifact.
