Dual-Electrode Deep Brain Stimulation for Addiction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current deep brain stimulation methods are inefficient in addressing psychological dependence in drug addiction, with high relapse rates due to inadequate control over psychological dependence, as medically assisted detoxification alone is insufficient.
Innovation Solution
A deep brain stimulation lead with two electrode groups, one positioned in the nucleus accumbens and the other in the anterior limb of the internal capsule, simultaneously stimulating these areas to control psychological dependence, using a control module and power module to deliver tailored electrical stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single electrode group stimulation is used, then device complexity is reduced, but therapeutic effectiveness for psychological dependence is insufficient
Solution Approach 1:
The lead is divided into multiple electrode groups (first electrode group in nucleus accumbens, second electrode group in anterior limb of internal capsule) that can be independently positioned and stimulated. This segmentation allows targeted stimulation of multiple brain regions involved in addiction pathways, improving therapeutic effectiveness while maintaining manageable device complexity through modular electrode design.
Solution Approach 2:
Multiple electrode groups are combined within a single lead structure, enabling simultaneous or coordinated stimulation of the nucleus accumbens and anterior limb of internal capsule. This merging approach achieves enhanced therapeutic effect by addressing multiple neural circuits involved in psychological dependence through one integrated device.
2Reliability
If multiple electrode groups are used to target multiple brain areas, then therapeutic effectiveness is improved, but device complexity increases
Solution Approach 1:
The lead structure is designed with universal multi-functionality, where a single lead body can accommodate multiple electrode groups that may be activated in different configurations. The control module can selectively activate the first electrode group, second electrode group, or both simultaneously, providing versatile therapeutic options without requiring multiple separate leads, thus improving effectiveness while controlling complexity.
3Reliability
If simultaneous stimulation of multiple brain areas is implemented, then control over psychological dependence is improved, but energy consumption increases
Solution Approach 1:
The control module can implement periodic or intermittent stimulation patterns across the multiple electrode groups, rather than continuous simultaneous stimulation. This allows for controlled energy delivery that maintains therapeutic effectiveness by periodically activating the first and second electrode groups, reducing overall energy consumption while still achieving control over psychological dependence through rhythmic neural modulation.
Solution Approach 2:
The stimulation system employs dynamic control where the control module can adjust which electrode groups are active at any given time, varying the stimulation pattern based on therapeutic needs. This dynamic activation allows simultaneous stimulation when maximum effect is needed, while also enabling energy-saving modes where only one electrode group is active, optimizing the balance between control effectiveness and energy consumption.

AI summary
Disclosed is a deep brain stimulation electrode, comprising at least two sets of output electrode contacts, and each set of output electrode contacts is at least provided with one output electrode contact. After installation, at least one output electrode contact of the first set of output electrode contacts is located at the nucleus accumbens septi part of the brain; after installation, at least one output electrode contact of the second set of output electrode contacts is located at the anterior limb of the internal capsule part of the brain. Further disclosed are a deep brain stimulation device comprising the electrode and a deep brain stimulation method for detoxification treatment. In the present invention, an electrode simultaneously stimulates the dual function zones of the nucleus accumbens septi and the anterior limb of internal capsule, and can selectively stimulate different intracerebral function zones, thus improving the effectiveness and safety of the deep brain stimulation in treating mental diseases such as drug addiction detoxification, obsessive-compulsive disorder, and depressive disorder.
