Solution Overview

Problem

Current treatments for vision disorders such as age-related macular degeneration (AMD) and geographic atrophy do not effectively prevent, slow, or restore vision loss, and existing electrical stimulation methods cause unacceptable side effects or provide only temporary relief.

Innovation Solution

A system using patterned electrical stimulation with biphasic and monophasic waveforms is applied transpalpebrally to the eye, with controlled amplitude, frequency, and duty cycle, and electrodes positioned near the anterior part of the eye and return electrodes posteriorly, to manage current density and minimize side effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrical stimulation is applied to treat vision disorders, then cellular function is improved and therapeutic effects are achieved, but side effects occur that are unacceptable

Engineering Contradiction:

Improvetherapeutic effectVSAvoidside effects

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by utilizing biphasic waveforms with specific amplitude, frequency, and duty cycle parameters to deliver electrical stimulation that achieves therapeutic effects while minimizing harmful side effects. The stimulation parameters are carefully controlled to optimize the therapeutic window between effective treatment and adverse reactions.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs periodic action through the use of pulsed electrical stimulation with defined duty cycles, where stimulation is delivered in repeated cycles rather than continuously. This periodic delivery allows tissue recovery between pulses, reducing cumulative damage and side effects while maintaining therapeutic benefit.

Inventive Principle:

Principle #19Periodic action

2Duration of action of moving object

If existing electrical stimulation methods are used, then temporary relief is provided, but the relief is not sustained and vision loss progression is not effectively prevented

Engineering Contradiction:

Improveduration of therapeutic effectVSAvoideffectiveness in preventing vision loss

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent implements continuity of useful action through repeated treatment sessions that maintain cumulative therapeutic effects over time. The system delivers stimulation in a structured regimen with multiple sessions spaced at appropriate intervals, ensuring continuous beneficial impact on retinal cell function and preventing regression to baseline.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent applies preliminary action by delivering electrical stimulation before significant vision loss or cell death occurs. The treatment aims to prevent pathological progression by maintaining cellular function in advance, rather than attempting to reverse established damage.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If current treatments for AMD and geographic atrophy are applied, then some symptomatic relief may be achieved, but they do not effectively prevent, slow, or restore vision loss

Engineering Contradiction:

Improveefficacy in preventing vision lossVSAvoidapplicability to different stages of disease

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent demonstrates universality by designing an electrical stimulation system that can be applied to multiple vision disorders including AMD and geographic atrophy. The same fundamental stimulation approach and device platform are adapted to treat different diseases and potentially different stages of disease progression, making the solution broadly applicable across various retinal conditions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A system and method for delivering ocular microstimulation therapy includes one or more active electrodes near the anterior part of the eye, one or more return electrodes on the patient, and a controller configured to generate electrical signals (e.g., anodal monophasic or biphasic pulses) with defined amplitude, current density, polarity, frequency, and duty cycle. The total electrode contact area is between about 1.5 cm2 and about 4 cm2. In some methods, the stimulation can be divided into subphases or varied in ramped or randomized patterns to reduce habituation. A therapy regimen can span multiple sessions, with data structures specifying session dates and modes, and whether treatment is unilateral or bilateral. Safety features detect hazardous reductions in electrode contact area.
