Ocular Platform Conduit for Posterior Eye Access

Solution Overview

Problem

Treating diseases and degenerations in the posterior portion of the eye, such as scleral staphyloma, is challenging due to the eye's strict positioning within the orbit bones, and existing methods like the retrobulbar approach can cause complications to ocular structures.

Innovation Solution

The use of ocular platforms and surgical tools that allow precise access to the posterior regions of the eye through the sclera, reducing the risk of complications by guiding tools to targeted locations without affecting adjacent tissues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If retrobulbar approach is used to treat posterior portion of the eye, then access to posterior regions is achieved, but complications to ocular structures such as retinal detachment may occur

Engineering Contradiction:

Improveaccess to posterior regionsVSAvoidrisk of complications

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a specialized surgical device as an intermediary tool that provides a controlled pathway through the sclera to reach posterior ocular structures. This mediator device includes a needle or catheter with specific design features that allow precise delivery of therapeutic agents while minimizing direct manipulation and potential damage to vulnerable ocular tissues like the retina.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical surgical approaches with less invasive methods, such as using injectable devices and minimally invasive catheters instead of open surgical instruments. This substitution reduces mechanical trauma to ocular structures while still achieving the therapeutic goal of treating posterior eye conditions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If injections are administered through the anterior portion of the eye, then delivery to posterior regions is achieved, but injected material spreads through the vitreous affecting other intra and extra ocular tissues

Engineering Contradiction:

Improvedelivery to posterior regionsVSAvoidspread of injected material

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent employs devices and methods that enable localized delivery of therapeutic agents directly to the target tissue in the posterior eye. The injection system is designed to deposit material at a specific location through the sclera, ensuring the therapeutic effect is concentrated where needed rather than diffusing through the vitreous humor to affect other ocular structures.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces a specialized surgical device as an intermediary tool that provides a controlled pathway through the sclera to reach posterior ocular structures. This mediator device includes a needle or catheter with specific design features that allow precise delivery of therapeutic agents while minimizing direct manipulation and potential damage to vulnerable ocular tissues like the retina.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If open surgical approach of the orbit is used, then access to optic nerve and adjacent structures is achieved, but surgical complexity and patient trauma increase

Engineering Contradiction:

Improveaccess to optic nerveVSAvoidsurgical approach complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical surgical approaches with less invasive methods, such as using injectable devices and minimally invasive catheters instead of open surgical instruments. This substitution reduces mechanical trauma to ocular structures while still achieving the therapeutic goal of treating posterior eye conditions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the parameters of the surgical approach by using smaller gauge needles, lower injection pressures, and controlled delivery rates. These parameter modifications allow access to the optic nerve and adjacent structures without requiring large incisions or complex surgical exposure, thereby reducing both device complexity and patient trauma.

Inventive Principle:

AI summary

A platform for introducing various treatment tools through a conduit in order to treat various ocular pathologies by attaching it to a human eyeball. The platform has an axis that defines opposing anterior and posterior axial directions. The platform includes a framework formed about the axis and the framework has anterior and posterior openings at respective anterior and posterior sides. The platform includes also a hollow conduit that extends through the framework while passing through the anterior and posterior openings.
