Abstract
Disclosed are methods and systems for treating epilepsy by stimulating a main trunk of a vagus nerve, or a left vagus nerve, when the patient has had no seizure or a seizure that is not characterized by cardiac changes such as an increase in heart rate, and stimulating a cardiac branch of a vagus nerve, or a right vagus nerve, when the patient has had a seizure characterized by cardiac changes such as a heart rate increase.
Claims14
A method of treating a medical condition in a patient using an implantable medical device, the implantable medical device including a first electrode coupled to a first cranial nerve structure and a second electrode coupled to a second cranial nerve structure, the method comprising:
- obtaining data relating to at least a portion of a heart beat complex from a patient;
- comparing the at least the portion of the heart beat complex to stored data relating to the patient;
- indicating an occurrence of a state change based upon a determination of the comparison;
- providing a first electrical signal to the first cranial nerve structure of the patient;
- and
- providing a second electrical signal to the second cranial nerve structure.
A method for indicating an occurrence of an epileptic seizure, comprising:
- obtaining via one or more processors of a medical device a kinetic data from a patient;
- indicating via the one or more processors of the medical device a possible occurrence of the epileptic seizure based on the kinetic data;
- obtaining via the one or more processors of the medical device a time series of heart beat complex data from the patient;
- determining via the one or more processors of the medical device at least one heart beat complex shape parameter for each of a plurality of heart beat complexes in the time series of heart beat complex data;
- comparing via the one or more processors of the medical device the at least one heart beat complex shape parameter for each of the plurality of heart beat complexes to a stored data relating to the patient;
- confirming via the one or more processors of the medical device the possible occurrence of the epileptic seizure as the occurrence of the epileptic seizure based upon the comparison;
- and
- providing an electrical signal to the first cranial nerve structure of the patient.
