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. 11,857,609.

Summary of the Inventive Concept

A paradigm shift in treating retinal edema, leveraging cutting-edge technologies to create a new generation of targeted, personalized, and non-invasive ocular delivery systems.

Background and Problem Solved

The original patent addressed retinal edema treatment with cell-permeant therapeutics, but its limitations include non-targeted delivery, potential side effects, and lack of real-time monitoring. The new inventive concept overcomes these limitations by introducing nanocarrier-based delivery devices, personalized treatment approaches, real-time monitoring capabilities, and non-invasive delivery methods.

Detailed Description of the Inventive Concept

The new inventive concept comprises four key components: (1) nanocarrier-based delivery devices engineered to bypass the blood-retina barrier and selectively target retinal Müller cells, (2) personalized treatment approaches using customized cocktails of cell-penetrating peptides and XIAP-BIR3 conjugates tailored to individual patients' genetic profiles and retinal edema severity, (3) real-time monitoring devices that detect changes in retinal thickness and transmit data to wearable devices, and (4) non-invasive delivery methods utilizing focused ultrasound and microbubbles to create temporary openings in the blood-retina barrier. These components work in concert to provide targeted, efficient, and personalized treatment of retinal edema.

Novelty and Inventive Step

The new inventive concept introduces a paradigm shift in retinal edema treatment by combining cutting-edge technologies to create a targeted, personalized, and non-invasive ocular delivery system. The novelty lies in the integration of nanocarrier-based delivery, personalized treatment approaches, real-time monitoring, and non-invasive delivery methods, which collectively overcome the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments may include the use of different types of nanocarriers, varying the composition of the cell-penetrating peptides and XIAP-BIR3 conjugates, or incorporating additional therapeutic agents into the delivery system. Variations may also include adapting the real-time monitoring device for use in other ocular diseases or integrating the non-invasive delivery method with other therapeutic approaches.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in the ocular disease treatment market, with potential applications in treating diabetic macular edema, retinal vein occlusion, and other retinal diseases. The market for ocular disease treatments is projected to grow significantly in the coming years, driven by an aging population and increasing prevalence of ocular diseases.
