This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,460.

Summary of the Inventive Concept

A next-generation ocular delivery system that leverages micro-robotics, gene-editing, nanofluidics, machine learning, and bio-absorbable materials to revolutionize glaucoma treatment and ocular therapy.

Background and Problem Solved

The original patent disclosed systems and methods for accessing Schlemm's canal and delivering a fluid composition to treat glaucoma. However, these systems have limitations in terms of precision, efficacy, and patient comfort. The new inventive concept addresses these limitations by introducing cutting-edge technologies to create a more targeted, efficient, and personalized approach to ocular treatment.

Detailed Description of the Inventive Concept

The new inventive concept encompasses a range of innovative solutions, including micro-robotic devices for targeted trabeculotomy, gene-editing payloads for upregulating aqueous humor outflow pathways, nanofluidic chips for real-time aqueous humor flow rate manipulation, machine learning algorithms for personalized treatment parameter prediction, and bio-absorbable stents for permanently dilating Schlemm's canal. These solutions are designed to work together to create a comprehensive and adaptive ocular treatment system.

Novelty and Inventive Step

The new claims introduce a paradigm shift in ocular delivery systems and methods, moving beyond the original patent's viscoelastic fluid-based approach to incorporate micro-robotics, gene-editing, and nanofluidics. The inventive step lies in the integration of these disparate technologies to create a novel, highly effective, and personalized treatment platform.

Alternative Embodiments and Variations

Alternative embodiments may include the use of different types of micro-robotic devices, gene-editing payloads, or nanofluidic chip designs. Variations may also include the incorporation of additional sensors or feedback mechanisms to further enhance the system's adaptability and efficacy.

Potential Commercial Applications and Market

The next-generation ocular delivery system has significant commercial potential in the glaucoma treatment and ocular therapy markets, with potential applications in hospitals, clinics, and ambulatory surgical centers. The system's adaptability and personalized approach may also enable new business models, such as subscription-based services or pay-per-procedure models.
