Flying Lead Electrode Configuration for Versatile Neural Stimulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantable medical devices, such as neural stimulators, are limited to a single function due to fixed electrode configurations, which can lead to redundancy and inefficiency in performing multiple therapeutic roles.
Innovation Solution
A flying lead electrode with an attachable portion that can be customized to suit different anatomical locations and functions, allowing for flexible adaptation during surgery by attaching various shapes and sizes of electrodes to the lead tip or along its length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed electrode configuration is used in implantable medical devices, then the device structure is simple and reliable, but the device can only perform a single function leading to redundancy and inefficiency
Solution Approach 1:
The patent implements a universal electrode lead system where a single lead design can accommodate multiple different electrode attachments suited for various anatomical locations and therapeutic functions. The lead includes a standardized connector interface that accepts different electrode configurations, allowing one lead to perform multiple functions rather than requiring separate dedicated leads for each function.
Solution Approach 2:
The electrode system is divided into separable components: a reusable lead body and interchangeable electrode attachments. This segmentation allows the lead to be detached from one electrode and connected to another, enabling functional versatility without requiring a completely different lead design for each application.
2Productivity
If multiple dedicated devices are used for different therapeutic functions, then each device can be optimized for its specific function, but redundancy increases and surgical efficiency decreases
Solution Approach 1:
The patent merges the functions of multiple dedicated electrode leads into a single universal lead system. By combining various electrode attachments with a common lead body, the system reduces the number of separate components that would otherwise be needed, thereby improving surgical efficiency and reducing redundancy.
3Manufacturing precision
If custom electrodes are designed for specific anatomical locations, then the treatment precision is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent segments the electrode system into a standardized lead body and specialized electrode attachments. The attachments can be pre-manufactured with location-specific geometries and electrical characteristics for precise anatomical targeting, while the lead body uses a standardized design that simplifies manufacturing. This segmentation allows precise custom electrodes to be produced more efficiently.

AI summary
A neural stimulator, suitable for implanting in a recipient, and having a flying lead with a configurable electrode. A benefit is an intra-operative ability to adjust the connection between the lead and an anatomically correct electrode, which obviates the need to manufacture multiple different configurations of implant to suit different placements of flying lead electrode.
