Embodiment Construction

[0028]Illustrative embodiments of the invention are described herein. In the interest of clarity, not all features of an actual implementation are described in this specification. In the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the design-specific goals, which will vary from one implementation to another. It will be appreciated that such a development effort, while possibly complex and time-consuming, would nevertheless be a routine undertaking for persons of ordinary skill in the art having the benefit of this disclosure.

[0029]This document does not intend to distinguish between components that differ in name but not function. In the following discussion and in the claims, the terms “including” and “includes” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to.” Also, the term “couple” or “couples” is intended to mean either a direct or an indirect electrical co...

Abstract

Disclosed herein are methods, systems, and apparatus for treating a medical condition in a patient using an implantable medical device (IMD). The IMD is capable of generating a first electrical signal for treating a medical condition, for example epilepsy. The first electrical signal relates to a long term therapy during a first time period in which there is no indication that the patient's brain is in an stable state, the first electrical signal being a microburst stimulation signal. The implantable device is also capable of generating a second electrical signal for treating the medical condition. The second electrical signal relates to a short term therapy during a second time period, in response to an indication that the patient's brain is in an unstable state. The second electrical signal in one example, may be a conventional stimulation signal.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to medical device systems and, more particularly, to medical device systems for applying electrical signals to a cranial nerve for the treatment of various medical conditions, and for providing a chronic condition therapy and an acute condition therapy using a microburst electrical signal and a non-microburst electrical signal.DESCRIPTION OF THE RELATED ART[0002]Many advancements have been made in treating diseases such as depression and epilepsy. Therapies using electrical signals for treating these diseases have been found to effective. Implantable medical devices have been effectively used to deliver therapeutic stimulation to various portions of the human body (e.g., the vagus nerve) for treating these diseases. As used herein, “stimulation” or “stimulation signal” refers to the application of an electrical, mechanical, magnetic, electromagnetic, photonic, audio and / or chemical signal to a neural structure in the patie...
