Solution Overview

Problem

Existing methods for treating diseases and disorders often require drug administration, and the afferent arc of the vagus nerve, which senses inflammatory status, remains incompletely understood.

Innovation Solution

Stimulating the vagus nerve with a disease-specific, condition-specific, or endogenous mediator-specific neurogram pattern to treat conditions such as inflammation, hypoglycemia, or hyperglycemia, using implantable electrodes to apply corrective stimulus patterns derived from neurograms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If implantable devices are used for nerve stimulation, then therapeutic effect is improved, but surgical implantation procedures and risks are introduced

Engineering Contradiction:
Improvetherapeutic effectVSAvoidsurgical implantation procedures
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical implantable device with a non-implantable external device that uses a wearable battery pack and external stimulator, eliminating the need for surgical implantation while maintaining nerve stimulation therapy

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

Solution Approach 2:

The patent extracts the battery and electronic components from the implantable device and places them in an external wearable battery pack, separating the power source from the patient's body to avoid surgical risks

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If non-implantable devices are used, then surgical risks are eliminated, but device mobility and flexibility are restricted

Engineering Contradiction:
Improvesurgical risksVSAvoiddevice mobility
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent divides the device into separate modular components: an external stimulator, a wearable battery pack, and a wireless communication module, allowing each component to be optimized independently for mobility and ease of use

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs wireless communication parameters and power transmission parameters to enable contactless operation, allowing the external device to maintain flexible positioning while providing continuous therapy

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If complex implantable devices are used, then therapy precision is improved, but device failure and revision surgery risks increase

Engineering Contradiction:
Improvetherapy precisionVSAvoiddevice failure risk
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent replaces complex implantable electronics with a simplified external device that achieves therapy precision through software-based control and wireless communication, eliminating the reliability risks associated with implantable components

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

Solution Approach 2:

The patent uses wireless communication to transmit control signals and data between the external device and the therapy system, creating a virtual connection that replicates the functionality of implantable devices without the associated risks

Inventive Principle:
Principle #26Copying
