Stimulation of a hypoglossal nerve for controlling the position of a patient's tongue
A method for controlling a position of a patient's tongue includes attaching at least one electrode to the patient's hypoglossal nerve, applying an electric signal through the electrode to the hypoglossal nerve to stimulate at least one muscle of the tongue at least until the number of obstructive sleep apnea occurrences are reduced from an initial level to a treatment level, and reducing the application of the electric signal while the number of obstructive sleep apnea occurrences remain generally at or below the treatment level.
1. A method for controlling a position of a patient's tongue, the method comprising:
attaching at least one electrode to the patient's hypoglossal nerve;
applying an electric signal through the at least one electrode to the hypoglossal nerve to stimulate at least one muscle of the tongue at least until a number of obstructive sleep apnea occurrences are reduced from an initial level to a treatment level; and
reducing at least one parameter of the electric signal while the number of obstructive sleep apnea occurrences remain generally at or below the treatment level.
2. The method of claim 1 , wherein reducing the at least one parameter of the electric signal includes applying the electric signal having an Intra-Session Periodicity.
3. The method of claim 1 , wherein reducing the at least one parameter of the electric signal includes applying the electric signal having an Inter-Session Periodicity.
4. The method of claim 1 , wherein reducing the at least one parameter of the electric signal includes reducing a duration that the electric signal is applied.
5. The method of claim 1 , wherein reducing the at least one parameter of the electric signal includes ceasing application of the electric signal.
6. The method of claim 1 , wherein reducing the at least one parameter of the electric signal includes reducing a frequency at which the electrical signal is applied.
7. The method of claim 1 , wherein reducing the at least one parameter of the electric signal includes reducing an amplitude at which the electric signal is applied.
8. The method of claim 1 further comprises:
applying an initial electric signal that gradually increases over time and then levels off.
9. The method of claim 1 , wherein the electric signal is applied to at least one targeted motor efferent of the hypoglossal nerve.
10. The method of claim 1 , wherein the electric signal is applied when the patient is asleep.
11. The method of claim 1 , wherein the electric signal is applied when the patient is awake.
12. A method for controlling a position of a patient's tongue, the method comprising:
attaching at least one electrode to the patient's hypoglossal nerve;
applying an electric signal through the at least one electrode to the hypoglossal nerve at an Inter-Session Periodicity to stimulate at least one muscle of the tongue to reduce the number of obstructive sleep apnea occurrences.
13. A method for controlling a position of a patient's tongue, the method comprising:
attaching at least one electrode to the patient's hypoglossal nerve;
applying an electric signal through the at least one electrode to the hypoglossal nerve at an Intra-Session Periodicity to stimulate at least one muscle of the tongue to reduce the number of obstructive sleep apnea occurrences.
14. A system for controlling a position of a patient's tongue, the system comprising:
at least one electrode configured to attach to the patient's hypoglossal nerve; and
an implantable pulse generator programmed to perform a method according to claim 1 .
15. A non-transitory computer readable storage medium having stored thereon computer-executable instructions which, when executed by a processor, perform a method according to claim 1 .
