Tropoelastin Peptide Wound Edge Application for Re-epithelialization

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current wound healing technologies face challenges in effectively improving re-epithelialization, particularly in skin wounds, which can lead to prolonged healing times and increased scar formation.

Innovation Solution

The use of tropoelastin, either alone or in combination with other materials like cross-linked hyaluronic acid gel, is applied directly to the wound edge to facilitate sustained contact and enhance re-epithelialization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional wound healing technologies are used, then wound healing occurs through natural processes, but re-epithelialization is slow and scar formation increases

Engineering Contradiction:

Improvere-epithelialization rateVSAvoidhealing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent applies tropoelastin to the wound edge before complete epithelialization occurs, during the proliferative phase. This preliminary application of elastin promotes keratinocyte migration and proliferation in advance, accelerating the re-epithelialization process and reducing overall healing time while minimizing scar formation

Inventive Principle:

Principle #10Preliminary action

2Productivity

If tropoelastin is applied to the wound, then re-epithelialization is accelerated, but sustained contact with the wound edge is required for effectiveness

Engineering Contradiction:

Improvere-epithelialization rateVSAvoidcontact duration

Core Design Contradiction:

ProductivityVSDuration of action of stationary object

Solution Approach 1:

The patent uses a carrier or delivery system that mediates between the tropoelastin and the wound edge, enabling sustained contact. This intermediary mechanism ensures the tropoelastin remains in contact with the wound edge for the necessary duration to promote keratinocyte migration and proliferation, thereby accelerating re-epithelialization without requiring continuous manual application

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method of healing a wound including contacting a wound edge with a tropoelastin or elastin derived peptide in conditions for enabling a sustained contact of the tropoelastin with the wound edge for a time period for enabling re-epithelialization of the wound.
