First Claim
Patent Images
1. An implantable medical device (IMD), comprising:
- a cardiac cycle determination module, the cardiac cycle determination module is configured to determine;
a cardiac cycle duration;
a delay duration, where the delay duration is determined based on being a predefined fraction of the determined cardiac cycle duration; and
a signal application duration, where the signal application duration is determined based on being a predetermined fraction of the determined cardiac cycle duration;
a lead assembly; and
a signal generator.

Abstract
A method of providing an electrical signal to a cranial nerve of a patient for treating a medical condition, including providing an electrical signal generator, coupling at least a first electrode to a cranial nerve of the patient and to the electrical signal generator, generating an electrical signal with the electrical signal generator, and applying the electrical signal to the cranial nerve, using the at least a first electrode, for a duration less than a cardiac period of the patient and during the cardiac period of the patient. In addition, an implantable medical device capable of implementing the method is disclosed.
