Trilaminar Inductive Matrix for Ocular Surface Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ocular surface reconstruction methods face challenges in maintaining structural integrity and functional stability due to damage from mechanical, chemical, or endogenous factors, leading to issues like conjunctivalization, scarring, and neovascularization, with current biological materials having limitations such as availability, autoimmune risks, and degradation issues.
Innovation Solution
Development of an inductive matrix for ocular surface reconstruction using absorbable materials that mimic the extracellular matrix (ECM) properties, providing structural support, promoting cell adhesion, migration, and differentiation, while being biocompatible and degradable to facilitate tissue regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing biological materials are used for ocular surface reconstruction, then tissue repair is promoted, but availability is limited and autoimmune risks increase
Solution Approach 1:
The patent creates an artificial extracellular matrix that copies the structural and functional properties of natural ECM without using actual biological tissues. This synthetic matrix mimics the natural environment that supports cell growth and tissue regeneration, thereby promoting tissue repair while avoiding the availability limitations and autoimmune risks associated with donor-derived biological materials
2Reliability
If existing biological materials are used for ocular surface reconstruction, then tissue repair is promoted, but degradation issues arise
Solution Approach 1:
The patent employs biodegradable polymers with controllable degradation rates, allowing the matrix to maintain structural stability during the critical tissue regeneration period and then degrade at a controlled pace. This parameter control ensures that the material provides sustained support for tissue repair while avoiding premature degradation that would compromise the repair process
3Reliability
If absorbable materials are used to mimic ECM properties, then structural support is provided and tissue regeneration is facilitated, but material complexity increases
Solution Approach 1:
The patent utilizes composite materials combining biodegradable polymers with bioactive molecules and growth factors within a porous architecture. This composite approach integrates multiple functions (structural support, cell adhesion, signaling) into a single material system, providing comprehensive ECM mimicry while managing complexity through synergistic material combinations rather than separate components

AI summary
A new method is provided that precisely harmonizes the structural and functional biological processes that lead to the optimal reconstruction of ocular surface disorders. The method consists of the administration of a trilaminar (3D) material, which comprises the mucosa, the basement membrane, and the submucosa of the porcine esophagus in a stabilized conformation of integrated layers, which accurately imitates ocular structures, whose mechanical properties, biocompatibility, and integration into the host's tissues, facilitate the structural and functional restoration of lost or damaged ocular tissues. Through the mimesis of the spatial microenvironments generated by their structure and their functional conjugation with the signals of the host's extracellular matrix, the reconstruction of the neo-tissue is successfully guided.
