Auto adjusting system for brain tissue stimulator
First Claim
1. A device for delivering therapy to a patient and soliciting information about the therapy from the patient comprising:
- a therapy module configured to provide a therapy characterized by at least one parameter to the patient;
a detection module configured to automatically detect a physiological event in the patient;
a controller configured to automatically determine the at least one parameter of the therapy based on the detected physiological event;
a prompting module configured to prompt the patient to express the patient'"'"'s opinion about the therapy; and
an input module configured to receive an input corresponding to the patient'"'"'s expressed opinion;
wherein the controller is further configured to automatically determine whether to change the at least one parameter of the therapy based on the detected physiological event and the expression of the patient'"'"'s opinion about the therapy.

Abstract
An implantable neurostimulator for treating disorders such as epilepsy, pain, movement disorders and depression includes a detection subsystem capable of detecting a physiological condition and a therapy subsystem capable of providing a course of therapy in response to the condition. The therapy subsystem includes an auto-adjust module for automatically adjusting one or more parameters of the therapy so that the therapy subsystem can provide an adjusted parameter to the patient and solicit the patient'"'"'s feedback concerning the adjustment without requiring the presence of, or immediate involvement with, a clinician or physician. The patient feedback can be analyzed by computer, clinician or a combination of both to determine an optimal range of parameters for subsequent courses of therapy. In this manner, information useful in tuning the neurostimulator therapy parameters to optimize them for individual patient can be acquired automatically outside of the traditional clinical setting, saving time and minimizing patient fatigue that otherwise would be experience in marathon, in-clinic tuning sessions. The auto-adjust module also can be configured to prompt the patient to provide feedback even when parameters are not being adjusted, so as to acquire information for a baseline or about any placebo effect when the patient is otherwise expecting changes to the therapy to be made.

13. A method of delivering electrical stimulation therapy provided to a patient with an implantable neurostimulator and soliciting information about the therapy from the patient comprising:
-
delivering a first course of electrical stimulation therapy with the implantable neurostimulator with a first value of at least one parameter of the electrical stimulation; automatically detecting with the implantable neurostimulator a physiological event in the patient; automatically changing the first value to a second value of the least one parameter based on the detected physiological event; delivering a second course of electrical stimulation therapy with the implantable neurostimulator to the patient with the second value; prompting the patient to provide input reflecting the patient'"'"'s opinion about the therapy; receiving an input corresponding to the patient'"'"'s expressed opinion about the therapy; automatically determining whether to change the at least one parameter of the therapy prior to delivering a third course of electrical stimulation therapy based on the detected physiological event and the input reflecting the patient'"'"'s opinion about the changed therapy; and if, it is determined to change the at least one parameter of the therapy prior to delivering a third course of electrical stimulation therapy, changing the at least one parameter of the therapy based on the detected physiological event and the input reflecting the patient'"'"'s opinion about the therapy. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A device for delivering therapy to a patient comprising:
-
means for stimulating the patient according to a first treatment of stimulation, the stimulating means being implantable in the patient; means for automatically detecting a physiological event in the patient; means for automatically varying at least one parameter of the first treatment of stimulation based on the detected physiological event; and means for prompting the patient to provide input about the therapy; means for receiving an input corresponding to the patient'"'"'s expressed opinion; wherein the varying means further automatically determines whether to vary the at least one parameter of the first treatment of stimulation based on the detected physiological event and the input about the therapy provided by the patient. - View Dependent Claims (23, 24, 25, 26, 27, 28)
