Methods and Systems of Treating Strabismus

1 . A method of treating a patient with strabismus, comprising:

providing a stimulator;

configuring one or more stimulation parameters to treat strabismus;

programming said stimulator with said one or more stimulation parameters;

generating a stimulus configured to treat said strabismus with said stimulator in accordance with said one or more stimulation parameters; and

applying said stimulus with said stimulator to a stimulation site within said patient;

wherein said stimulation site comprises at least one or more of an extraocular muscle and a cranial nerve innervating said extraocular muscle.

2 . The method claim 1 , wherein said extraocular muscle comprises at least one or more of a medial rectus muscle, a lateral rectus muscle, a superior rectus muscle, an inferior rectus muscle, a superior oblique muscle, and an inferior oblique muscle.

3 . The method of claim 1 , wherein said cranial nerve comprises at least one or more of an oculomotor nerve, a trochlear nerve, and an abducens nerve.

4 . The method of claim 1 , wherein said stimulator is coupled to one or more electrodes, and wherein said stimulus comprises a stimulation current delivered via said electrodes.

5 . The method of claim 1 , wherein said stimulus comprises an infusion of one or more drugs at said stimulation site.

6 . The method of claim 1 , further comprising evaluating an effectiveness of said stimulus and adjusting said stimulation parameters in accordance with said evaluation.

7 . The method of claim 1 , further comprising at least partially implanting said stimulator within said patient.

8 . The method of claim 1 , further comprising configuring said one or more stimulation parameters such that said stimulus is configured to induce contraction of one or more of said extraocular muscles.

9 . The method of claim 1 , further comprising configuring said one or more stimulation parameters such that said stimulus is configured to induce relaxation of one or more of said extraocular muscles.

10 . The method of claim 1 , further comprising sensing at least one indicator related to said strabismus and using said at least one sensed indicator to adjust one or more of said stimulation parameters.

11 . A method of treating strabismus, said method comprising:

implanting a stimulator at least partially within a patient;

configuring one or more stimulation parameters to treat strabismus;

programming said stimulator with said one or more stimulation parameters;

generating a stimulation current configured to treat said strabismus with said stimulator in accordance with said one or more stimulation parameters; and

applying said stimulation current with said implanted stimulator to a stimulation site within said patient;

wherein said stimulation site comprises at least one or more of an extraocular muscle and a cranial nerve innervating said extraocular muscle.

12 . The method claim 11 , wherein said extraocular muscle comprises at least one or more of a medial rectus muscle, a lateral rectus muscle, a superior rectus muscle, an inferior rectus muscle, a superior oblique muscle, and an inferior oblique muscle.

13 . The method of claim 11 , wherein said cranial nerve comprises at least one or more of an oculomotor nerve, a trochlear nerve, and an abducens nerve.

14 . The method of claim 11 , further comprising configuring said one or more stimulation parameters such that said stimulus is configured to induce contraction of one or more of said extraocular muscles.

15 . The method of claim 11 , further comprising configuring said one or more stimulation parameters such that said stimulus is configured to induce relaxation of one or more of said extraocular muscles.

16 . The method of claim 11 , further comprising sensing at least one indicator related to said strabismus and using said at least one sensed indicator to adjust one or more of said stimulation parameters.

17 . A system for treating a patient with strabismus, said system comprising:

a stimulator configured to generate at least one stimulus in accordance with one or more stimulation parameters adjusted to treat strabismus;

a programmable memory unit in communication with said stimulator and programmed to store said one or more stimulation parameters to at least partially define said stimulus such that said stimulus is configured to treat said strabismus; and

means, operably connected to said stimulator, for applying said stimulus to a stimulation site within said patient;

wherein said stimulation site comprises at least one or more of an extraocular muscle and a cranial nerve innervating said extraocular muscle.

18 . The system claim 17 , wherein said extraocular muscle comprises at least one or more of a medial rectus muscle, a lateral rectus muscle, a superior rectus muscle, an inferior rectus muscle, a superior oblique muscle, and an inferior oblique muscle.

19 . The system of claim 17 , wherein said cranial nerve comprises at least one or more of an oculomotor nerve, a trochlear nerve, and an abducens nerve.

20 . The system of claim 17 , wherein said means for applying said at least one stimulus comprises one or more electrodes, and wherein said stimulus comprises a stimulation current delivered via said electrodes.
