Elastase-Treated Arterial Tissue Hydrogel for Biocompatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydrogels made from synthetic and biological materials have poor biocompatibility due to extensive chemical modification, hindering tissue treatment and regeneration.
Innovation Solution
A tissue-derived hydrogel is created by treating an acellular arterial tissue matrix with elastase, which increases biocompatibility and reduces immunogenicity, allowing the hydrogel to swell and become more malleable while retaining structural integrity and promoting native tissue re-growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If synthetic materials and extensive chemical modification are used to produce hydrogels, then hydrogel production is achieved, but biocompatibility deteriorates
Solution Approach 1:
The patent extracts and removes cells from arterial tissue to create an acellular matrix, eliminating immunogenic cellular components while retaining the beneficial extracellular matrix structure. This extraction process resolves the contradiction by removing harmful elements (cells that cause immune rejection) while preserving the useful framework for tissue regeneration
Solution Approach 2:
The patent applies elastase enzyme treatment to modify the physical and chemical parameters of the arterial tissue matrix. This enzymatic treatment alters the tissue's mechanical properties, increasing swelling and softening the matrix, thereby transforming it into a hydrogel state with improved biocompatibility and reduced immunogenicity
2Reliability
If arterial tissue is treated with elastase, then biocompatibility improves and immunogenicity reduces, but tissue structural integrity may compromise
Solution Approach 1:
The patent uses elastase enzyme as an intermediary agent to selectively degrade specific components of the tissue matrix. The enzyme acts as a mediator that transforms the rigid arterial tissue into a softer hydrogel state while maintaining the overall structural framework necessary for tissue support and regeneration
Solution Approach 2:
Controlled enzymatic treatment with elastase modifies the physical parameters of the tissue matrix, inducing swelling and softening transitions. These parameter changes transform the tissue from a rigid state to a more compliant hydrogel state, improving biocompatibility while preserving essential structural integrity through controlled modification
