Nerve Regeneration Stimulation Device With Continuous Percutaneous Leads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical treatments for nerve injuries do not provide immediate restoration of function due to the slow growth rate of nerve fibers, and existing methods lack effective means for initiating electrical stimulation during or after surgery without interrupting the process.
Innovation Solution
A system comprising a stimulation device with a housing, control circuitry, electrodes, and a percutaneous lead that allows for electrical stimulation of nerve tissue during and after surgery, enabling continuous nerve regeneration therapy without the need for repeated electrode replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical intervention is performed to repair nerve injuries, then the likelihood of regaining motor control or sensation is improved, but the recovery time is extended due to the slow growth rate of nerve fibers
Solution Approach 1:
The system enables preliminary electrical stimulation to be applied during surgery before the nerve repair is completed and before the patient leaves the operating room. This preliminary action initiates the regeneration process early, potentially reducing the overall recovery time while maintaining the improved reliability of surgical intervention
2Duration of action of stationary object
If electrical stimulation is initiated during surgery and continued post-operatively, then the continuity of nerve regeneration therapy is improved, but the complexity of maintaining stimulation across different settings is increased
Solution Approach 1:
The stimulation device is designed with universal functionality to operate in multiple settings (operating room and post-operative environments) without requiring interruption or replacement. The device can function with different power sources and maintain continuous operation across different locations, simplifying the transition from surgical to post-operative care while maintaining therapy continuity
3Adaptability or versatility
If repeated electrode replacements are required for each stimulation period, then the ability to deliver multiple stimulation courses is improved, but the time loss and procedural complexity increase
Solution Approach 1:
The system enables continuous electrical stimulation therapy without interruption or electrode replacement. The device maintains functional operation throughout the entire recovery period, eliminating the time loss and procedural complexity associated with repeated electrode replacements while preserving the ability to deliver multiple stimulation courses

AI summary
A stimulation device includes an adaptor component. The adaptor component couples a percutaneous lead to the stimulation device. The stimulation device may apply a stimulation signal to target tissue via the adaptor. A surgeon may place the stimulation device in a container and the adaptor component may be disposed outside of the container. Methods describe prolonged stimulation of target tissue via a stimulation device. The prolonged stimulation may be applied during and after a surgical procedure.
