AI Technical Summary

Problems solved by technology

However, given the anatomical or neurological variability between patients, and the relatively large size of each electrode contact relative to the neural structure of interest, stereotaxic positioning generally does not optimize treatment efficacy or enable stimulation power. minimize

Embodiment Construction

[0035] figure 1 An implanted deep brain stimulator 100 is schematically shown. The stimulator 100 includes an electronics module 110 implanted at a suitable location in the patient's chest, and two electrode assemblies 150, 152 implanted in the brain and connected to the module 110 by suitable leads. Many aspects of the operation of the implanted neural device 100 can be reconfigured by an external control device (not shown). Also, the implanted neural device 100 functions as a data collector, wherein the collected data is communicated to an external device.

[0036] figure 2 is a block diagram of the implanted neurostimulator 100. Module 110 includes a battery 112 and a telemetry module 114 . In embodiments of the present invention, telemetry module 114 may use any suitable type of transcutaneous communication, such as infrared (IR) transmission, electromagnetic transmission, capacitive transmission, and inductive transmission, to transfer power and / or data.

Abstract

Fitting a brain neurostimulator electrode array comprises positioning at least a first electrode in a desired target structure in a first cerebral hemisphere, and positioning at least a second electrode in a corresponding target structure in a contralateral cerebral hemisphere. Electrical stimuli are applied from the first electrode to the desired target structure. Neural responses observed at thesecond electrode in response to the electrical stimuli are recorded. The fitting of at least one of the first electrode and second electrode is assessed by reference to the recorded neural responses.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Australian Provisional Patent Application No. 2015902021 filed 31 May 2015, which is incorporated herein by reference. technical field [0003] The present invention relates to neuromodulation in the brain, in particular to a method for monitoring activity in the brain due to stimulation in order to optimize implantation of deep brain stimulator (DBS) electrode arrays and / or to optimize implanted DBS arrays postoperative assembly. Background technique [0004] Neuromodulation involves the application of electrical stimulation to biological tissue to produce a therapeutic effect. Neuromodulation can be non-invasive, such as by transcutaneous electrical nerve stimulation (TENS), transcranial magnetic stimulation (TMS); or highly invasive when one or more electrodes need to be implanted and the stimulator controlled, as in In the case of deep brain stimulation (DBS). DBS has beco...
