Solution Overview

Problem

Current deep brain stimulation (DBS) therapies effectively treat motor symptoms of Parkinson's disease but fail to address associated sleep disturbances, which significantly impact quality of life and are often resistant to existing treatments with adverse side effects.

Innovation Solution

DBS systems are enhanced to detect sleep stages and provide targeted stimulation using novel algorithms and electrodes, allowing for simultaneous treatment of motor and sleep symptoms through multi-modal neuromodulation, reducing the need for medications and minimizing side effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If DBS therapy is used to treat motor symptoms of PD, then motor symptoms are effectively treated, but sleep disturbances remain untreated

Engineering Contradiction:
Improvemotor symptom treatment effectivenessVSAvoidtherapeutic coverage for sleep disorders
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The DBS system is enhanced to perform multiple functions: it continues to treat motor symptoms while simultaneously detecting sleep stages and providing targeted sleep therapy. The single implantable device now serves dual purposes, eliminating the need for separate treatments for motor and sleep symptoms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces sleep stage detection algorithms and targeted stimulation protocols as intermediary mechanisms that enable the DBS system to bridge between motor symptom treatment and sleep disorder treatment. These intermediaries allow the system to adapt stimulation parameters based on detected sleep stages.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If pharmaceutical interventions are used to treat sleep disturbances, then sleep quality may improve, but adverse side effects and cognitive impairment occur

Engineering Contradiction:
Improvesleep disturbance treatment effectivenessVSAvoidadverse side effects and cognitive impairment
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces pharmaceutical chemical interventions with electrical stimulation therapy delivered by the DBS system. This substitution eliminates exposure to medication side effects while providing targeted neuromodulation to improve sleep quality through electrical rather than chemical mechanisms.

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

Solution Approach 2:

The DBS system provides self-regulated therapy by automatically detecting sleep stages and adjusting stimulation parameters accordingly. The system monitors its own therapeutic effect through continuous sleep stage detection and adapts its operation to maintain optimal sleep quality without external medication intervention.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If DBS systems are enhanced with sleep detection and targeted stimulation, then sleep quality improves, but device complexity increases

Engineering Contradiction:
Improvemulti-modal neuromodulation capabilityVSAvoidDBS system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The enhanced DBS system integrates sleep stage detection algorithms and targeted stimulation capabilities into the existing implantable device architecture. By making the device multi-functional, it can perform both motor symptom treatment and sleep disorder therapy without requiring completely separate systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges sleep detection functionality and sleep-targeted stimulation protocols with the existing DBS hardware and software. The algorithms for detecting sleep stages are integrated into the device's processing capabilities, and stimulation parameters are combined to address both motor and sleep symptoms simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If multiple separate treatments are provided for motor and sleep symptoms, then comprehensive symptom coverage is achieved, but treatment cost and complexity increase

Engineering Contradiction:
Improvesymptom coverageVSAvoidnumber of interventions
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The DBS system is designed as a universal platform that can treat multiple symptom types through a single implantable device. By providing both motor symptom relief and sleep disorder therapy through one system, it eliminates the need for multiple separate interventions and reduces overall treatment complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines motor symptom treatment and sleep disorder therapy into a unified treatment protocol delivered by the same DBS device. The merging of these therapies allows comprehensive symptom coverage while reducing the number of separate interventions required.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Described here is a deep brain stimulation (“DBS”) approach that targets several relevant nodes within brain circuitry, while monitoring multiple symptoms for efficacy. This approach to multi-symptom monitoring and stimulation therapy may be used as an extra stimulation setting in extant DBS devices, particularly those equipped for both stimulation and sensing. The therapeutic efficacy of DBS devices is extended by optimizing them for multiple symptoms (such as sleep disturbance in addition to movement disorders), thus increasing quality of life for patients.
