Abstract

A method for stimulating a portion of a vagus nerve of a patient to treat a pancreatic disorder is provided. At least one electrode is coupled to at least one portion of an autonomic nerve of the patient. The portion may include a celiac plexus, a superior mesenteric plexus, and a thoracic splanchnic. An electrical signal is applied to the portion of the vagus nerve using the electrode to treat the pancreatic disorder.

Claims

1. A method of treating a patient having a pancreatic disorder, comprising:

coupling at least one electrode to at least one portion of a celiac plexus; and

applying an electrical signal to said at least one portion of said celiac plexus using said electrode to treat said pancreatic disorder.

2. The method of claim 1, wherein said pancreatic disorder comprises at least one of an low blood-glucose level, high blood-glucose level, abnormal level of digestion enzymes, heart-rate fluctuations due to hormonal imbalance, hypoglycemia, hyperglycemia, Type 1 diabetes, Type 2 diabetes, ketoacidosis, celiac disease, and a kidney disorder.

3. The method of claim 1, wherein applying an electrical signal to said at least one portion of said celiac plexus using said electrode to treat said pancreatic disorder comprises adjusting at least one of a insulin level, a hormones level, a digestive enzymes level, and a glycogen level produced by a pancreas.

4. The method of claim 1, further comprising coupling said at least one electrode to a at least one portion of said nerve selected from a group consisting of a thoracic splanchnic nerve, said celiac plexus of said vagus nerve, and a superior mesenteric plexus.

5. The method of claim 1, further comprising generating a physiological response to said electrical signal that is selected from the group consisting of an afferent action potential, an efferent action potential, an afferent hyperpolarization, a sub-threshold depolarization, and an efferent hyperpolarization.

6. The method of claim 5, wherein applying the electrical signal comprises generating an efferent action potential in combination with an afferent action potential.

7. The method of claim 1, further comprising the steps of:

providing a programmable electrical signal generator;

coupling said signal generator said at least one electrode;

generating an electrical signal with the electrical signal generator;

and applying the electrical signal to the electrode.

8. The method of claim 7, further comprising programming the electrical signal generator to define the electrical signal by at least one parameter selected from the group consisting of a current magnitude, a pulse frequency, a pulse width, an on-time and an off-time, wherein said at least one parameter is selected to treat the pancreatic disorder.

9. The method of claim 1, further comprising detecting a symptom of the pancreatic disorder, and wherein applying the electrical signal is initiated in response to detecting said symptom.

10. The method of claim 9, wherein the detecting the symptom comprises using at least one of a blood-glucose level, a high blood-glucose level, a hormonal imbalance factor, a factors relating to a digestive enzyme, a ketone level, and a urine-glucose level.

11. The method of claim 1, wherein applying the electrical signal comprises applying said signal during a first treatment period, and said method further comprises applying a second electrical signal to the autonomic nerve using said at least one electrode during a second treatment period to treat the pancreatic disorder.

12. The method of claim 11, further comprising detecting a symptom of said pancreatic disorder, wherein detecting the symptom comprises using at least one of a blood-glucose level factor, high blood-glucose level sensor, a hormonal imbalance sensor, a sensor relating to a factor relating to a digestive enzyme, ketone sensor, a urine-glucose level sensor;

and wherein the second treatment period is initiated in response to said step of detecting a symptom of the pancreatic disorder.

13. A method of treating a patient having a pancreatic disorder, comprising:

coupling at least one electrode to at least a portion of a celiac plexus;

providing an electrical signal generator;

coupling said signal generator to said at least one electrode;

generating an electrical signal with the electrical signal generator; and

applying the electrical signal to the electrode to treat said pancreatic disorder.

14. The method of claim 13, further comprising:

detecting a symptom of the pancreatic disorder, wherein the step of applying the electrical signal to the electrode is initiated in response to detecting said symptom.

15. The method of claim 13, further comprising coupling said at least one electrode to at least a thoracic splanchnic nerve, a superior mesenteric plexus, and said celiac plexus of said vagus nerve.

16. A method of treating a patient having a pancreatic disorder, comprising:

coupling at least one electrode to at least a portion of an autonomic nerve of the patient selected from a group consisting of a celiac plexus of said vagus nerve, a superior mesenteric plexus, and a thoracic splanchnic; and

applying an electrical signal to said at least one portion of said autonomic nerve using said electrode to treat said pancreatic disorder.

17. The method of claim 16, further comprising:

providing a programmable electrical signal generator;

coupling said signal generator to said at least one electrode;

generating an electrical signal with said electrical signal generator; and

wherein applying an electrical signal to said at least portion of said autonomic nerve comprises applying the electrical signal to said at least one electrode.

18. The method of claim 17, further comprising:

programming the electrical signal generator to define said electrical signal by a plurality of parameters selected from the group consisting of a current magnitude, a pulse width, a pulse frequency, an on-time and an off-time.

19. The method of claim 16, wherein applying an electrical signal to said portion of said autonomic nerve comprises applying said signal during a first treatment period, said method further comprising applying a second electrical signal to the at least one branch of a vagus nerve during a second treatment period.

20. The method of claim 19, wherein said first treatment period comprises a period ranging from one hour to six months, and wherein said second treatment period comprises a period ranging from one month to 10 years.

21. The method of claim 16, wherein the at least one electrode is selected from the group consisting of a spiral electrode and a paddle electrode.

22. The method of claim 16, wherein applying an electrical signal to said at least one branch of said vagus nerve using said electrode comprises performing an electrical stimulation, the method further comprising performing said electrical stimulation in combination with at least one of a magnetic stimulation, a chemical stimulation, and a biological stimulation.
