Apparatus and methods for applying neural stimulation to a patient
View Patent ↗Systems and methods for neural stimulation may include a stimulus unit; a first electrode assembly having a first set of contacts; and a second set of contacts. The stimulus unit can be an implantable pulse generator including a first terminal that can be biased at a first signal polarity and a second terminal that can be biased at a second signal polarity. The first electrode assembly includes a support member configured to be placed at the stimulation site, the first set of contacts carried by the support member, and a first lead configured to be attached to the first terminal of the implantable pulse generator for biasing the surface contacts at the first polarity. The second set of contacts is detached from the surface electrode assembly. The second set of contacts can be one or more conductive elements fixed to or forming portions of the implantable pulse generator, or a separate electrode array.
1. A method for treating a patient, comprising:
implanting at least one electrode beneath the patient's skull and on the dura over a target cortical auditory neural population of the patient's brain; and
affecting a functioning of the target auditory neural population by engaging the patient in a treatment regimen that includes:
directing an electrical signal from the at least one electrode to the target neural population; and
engaging the patient in an adjunctive therapy.
2. The method of claim 1 wherein engaging the patient in an adjunctive therapy includes engaging the patient in an auditory task.
3. The method of claim 1 wherein engaging the patient in an adjunctive therapy includes engaging the patient in cognitive therapy.
4. The method of claim 3 wherein engaging the patient in an adjunctive therapy includes engaging the patient in a thought task.
5. The method of claim 3 wherein engaging the patient in an adjunctive therapy includes engaging the patient in a memory task.
6. The method of claim 1 wherein implanting at least one electrode includes implanting at least one electrode proximate to the auditory cortex.
7. The method of claim 1 wherein affecting a functioning of the target auditory population includes treating a tinnitus condition of the patient.
8. A method for treating a tinnitus in a patient, comprising:
implanting at least one electrode beneath the patient's skull and on the dura over a target cortical auditory neural population of the patient's brain such that at least one electrode is positioned over the auditory cortex; and
affecting a functioning of the target auditory neural population by engaging the patient in a treatment regimen that includes:
directing an electrical signal from the at least one electrode to the target neural population; and
engaging the patient in an adjunctive therapy.
