Solution Overview

Problem

Current methods for treating medical conditions such as epilepsy, headaches, and neurodegenerative diseases like Alzheimer's are inadequate, as they either have modest success in treating symptoms or fail to stop disease progression, and existing treatments often come with side effects or require invasive procedures.

Innovation Solution

Non-invasive electrical stimulation of the vagus nerve using a mobile device with adjustable stimulation parameters to release inhibitory neurotransmitters like norepinephrine and acetylcholine, transitioning microglial cells from a destructive to a reparatory phenotype, thereby reducing neuroinflammation and slowing disease progression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If invasive procedures are used to treat medical conditions, then treatment effectiveness is improved, but patient risk and complexity increase

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidinvasive procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces invasive mechanical surgical procedures with non-invasive electrical stimulation delivery through a mobile device. The electrical stimulation is transmitted through the skin without surgical intervention, eliminating the need for implanted electrodes while maintaining therapeutic effectiveness for conditions like migraine and epilepsy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mobile device serves as an intermediary between the user and the treatment delivery system. It transmits electrical stimulation through the skin to target nerves without requiring direct surgical access, acting as a mediator that enables non-invasive therapeutic delivery.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If conventional treatments are used for neurodegenerative diseases, then symptom management is provided, but disease progression is not stopped

Engineering Contradiction:
Improvesymptom managementVSAvoiddisease progression control
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent changes the therapeutic parameter from simple symptom management to disease-modifying treatment by using electrical stimulation to trigger neuroprotective mechanisms. The stimulation parameters are adjusted to activate specific neural pathways that can slow or arrest neurodegenerative processes, not just mask symptoms.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If existing treatments are administered, then medical conditions are treated, but significant side effects occur

Engineering Contradiction:
Improvecondition treatmentVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces pharmacological treatments with electrical stimulation therapy. This substitution eliminates the side effects associated with medications while maintaining effective treatment for conditions like migraine and epilepsy, as the electrical stimulation directly modulates neural activity without chemical intermediaries.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Devices, systems, and methods are disclosed that allow a patient to self-treat a medical condition, such as a migraine headache,an epileptic seizure, a neurodegenerative disease, such as dementia, Alzheimer's disease, ischemic stroke, post-concussion syndrome, chronic traumatic encephalopathy or the like, by electrical non-invasive stimulation of a vagus nerve. The system can comprise a handheld stimulator which is applied to a surface of the patient's neck, wherein the stimulator comprises or is joined to a mobile device. A camera of the mobile device may be used to position and reposition the stimulator to a particular location on the patient's neck. The system may also comprise a base station that is used to meter the charging of a rechargeable battery within the stimulator. The base station and stimulator transmit data to one another regarding the status of a stimulation session.
