A method for stimulating a portion of a vagus nerve of a patient to treat a pulmonary disorder is provided. At least one electrode is coupled to at least one portion of a left vagus nerve and/or a right vagus nerve of the patient. An electrical signal is applied to the portion of the vagus nerve using the electrode to treat the pulmonary disorder. The electrical signal may perform a blocking of an intrinsic neural activity on said at least one portion of the left vagus nerve and said right vagus nerve.

Stimulating cranial nerve to treat pulmonary disorder

A method and an apparatus for projecting an end of service (EOS) and/or an elective replacement indication (ERI) of a component in an implantable device and for determining an impedance experienced by a lead associated with the implantable device. An active charge depletion of an implantable device is determined. An inactive charge depletion of the implantable device is determined. A time period until an end of service (EOS) and/or elective replacement indication (ERI) of a power supply associated with the IMD based upon the active charge depletion, the inactive charge depletion, and the initial and final (EOS) battery charges, is determined. Furthermore, to determine the impedance described above, a substantially constant current signal is provided through a first terminal and a second terminal of the lead. A voltage across the first and second terminals is measured. An impedance across the first and second terminals is determined based upon the constant current signal and the measured voltage.

Power supply monitoring for an implantable device

A method and apparatus for stimulating a portion of a vagus nerve of a patient to treat a gastrointestinal disorder is provided. At least one electrode is coupled to at least one portion of a vagus nerve of the patient. The portion of the a vagus nerve may include an esophageal plexus, a myenteric plexus of aurbach, a submucous plexus of the meissner, a principal nerve of the lesser curvature of the stomach, and a gastric branch of said vagus nerve. An electrical signal is applied to the portion of the vagus nerve using the electrode to treat the gastrointestinal disorder.

Autonomic nerve stimulation to treat a gastrointestinal disorder

Disclosed is a method of treating a patient having a vocal cord disorder, comprising coupling at least one electrode to at least one cranial nerve of the patient, wherein the cranial nerve is selected from the group consisting of a vagus nerve, a trigeminal nerve, and a glossopharyngeal nerve, and applying an electrical signal to the cranial nerve using the electrode to treat the vocal cord disorder. The electrode may be coupled to a branch of the vagus nerve selected from the group consisting of a recurrent laryngeal nerve, the external branch of a superior laryngeal nerve, the internal branch of a superior laryngeal nerve, and a pharyngeal plexus. Also disclosed is a computer readable program storage device encoded with instructions that, when executed by a computer, perform the method, and a medical device and a vocal cord disorder treatment system that may be used in performance of the method.

Cranial nerve stimulation to treat a vocal cord disorder

A method, system, and an apparatus for stimulating a cranial nerve of a patient to treat a disorder, such as a metabolic or an endocrine disorder associated with the thyroid gland with an implantable medical device are provided. The method comprises coupling an electrode to the cranial nerve selected from the group consisting of a vagus nerve, a trigeminal nerve, and a glossopharyngeal nerve. The method further includes generating an electrical signal to treat a disorder associated with the thyroid gland. The electrical signal may be applied to the cranial nerve using the electrode to provide electrical nerve stimulation therapy to the patient. For treating a patient with a metabolic or an endocrine disorder associated with the thyroid gland, a neurostimulator may be adapted to apply an electrical stimulus to the vagus nerve and/or a branch of the vagus nerve associated with the thyroid gland. By balancing hormonal imbalance, the neurostimulator may provide electrical nerve stimulation therapy to the patient, thereby treating a target metabolic or an endocrine disorder associated with the thyroid gland.
