Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nerve compression syndromes, such as carpal tunnel syndrome, impede neural signal propagation due to compression, trauma, or structural abnormalities, leading to pain, weakness, and muscle atrophy, with existing treatments offering temporary relief or side effects.
Innovation Solution
A stimulator is implanted to apply hyperpolarizing electrical stimulation current to damaged neural tissue, enhancing signal transmission by regulating voltage-gated sodium channels, thereby improving neural signal propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional treatments (braces, massages, steroids, surgery) are used to treat nerve compression, then temporary relief or symptom management is achieved, but the treatments are ineffective long-term, offer only temporary relief, or cause undesirable side effects
Solution Approach 1:
The patent applies hyperpolarizing electrical stimulation with specific parameters (voltage, duration, frequency) to alter the excitability of damaged neural tissue. By changing the electrical parameters of stimulation, the invention promotes long-term recovery of nerve conduction without the side effects associated with traditional treatments like steroids or surgery.
Solution Approach 2:
The invention replaces mechanical treatments (braces, massages, surgical intervention) with electrical stimulation therapy. This substitution eliminates the harmful effects of mechanical compression relief methods while providing a non-invasive approach to enhance neural signal transmission through damaged tissue.
2Stress or pressure
If nerve compression is treated with surgical procedures to relieve pressure, then pressure on the nerve is reduced, but the treatment is invasive and may cause other undesirable side effects
Solution Approach 1:
The patent replaces invasive surgical mechanical decompression with non-invasive electrical stimulation. Instead of physically relieving pressure through surgery, the invention uses hyperpolarizing electrical current to enhance neural signal transmission through the compressed tissue, avoiding surgical complexity and associated risks.
Solution Approach 2:
The invention introduces electrical stimulation as an intermediary mechanism to bridge the gap between nerve compression and functional recovery. Rather than directly removing the compressive force through surgery, the electrical stimulation mediates the recovery process by modulating neural excitability and promoting signal transmission through damaged tissue.
3Reliability
If depolarizing stimulation is applied to damaged neural tissue, then neural excitation is increased, but the damaged tissue remains inexcitable or has reduced excitability due to compression, trauma, or degeneration
Solution Approach 1:
The patent inverts the conventional approach to neural stimulation. Instead of applying depolarizing stimulation to increase excitability, it applies hyperpolarizing stimulation (making the membrane potential more negative) which paradoxically increases excitability in damaged tissue by removing inactivation of voltage-gated sodium channels and facilitating subsequent action potential generation.
Solution Approach 2:
The invention changes the fundamental parameter of stimulation polarity from depolarizing (positive) to hyperpolarizing (negative). This parameter change fundamentally alters the mechanism of action, allowing damaged neural tissue to become excitable again by resetting the state of voltage-gated ion channels without requiring direct depolarization.
