Solution Overview

Problem

Existing acellular dermal matrix sheet allografts with parallel mesh patterns allow stretch only in a single direction, limiting their versatility and fluid drainage capabilities.

Innovation Solution

Development of mesh patterns with non-parallel lines, such as alternating, intersecting, diamond, herringbone, and multiple quadrant patterns, allowing stretch in multiple directions and enhancing fluid drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If parallel mesh lines are used in the acellular dermal matrix sheet, then the mesh pattern provides structural support, but stretch is limited to a single direction

Engineering Contradiction:

Improvetensile strengthVSAvoidstretch direction

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The mesh pattern is segmented into multiple sets of lines oriented in different directions (e.g., first set in a first direction, second set in a second direction). This segmentation allows the structure to accommodate stretching in multiple directions while maintaining structural support through each individual line set

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mesh pattern uses asymmetric line arrangements where lines are not uniformly parallel but are oriented at different angles relative to each other. This asymmetric configuration enables the material to respond to multidirectional forces while maintaining overall structural integrity

Inventive Principle:

Principle #4Asymmetry

2Stability of the object's composition

If parallel mesh lines are used in the acellular dermal matrix sheet, then the mesh pattern provides structural stability, but fluid drainage capability is limited

Engineering Contradiction:

Improvestructural stabilityVSAvoidfluid drainage

Core Design Contradiction:

Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The mesh pattern divides the structure into multiple directional line sets, creating interconnected void spaces that facilitate fluid drainage pathways in multiple directions while preserving structural stability through the distributed line network

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mesh pattern creates a porous structure with controlled void spaces between the line sets. These pores are strategically arranged to allow fluid drainage while the intersecting line patterns maintain structural stability

Inventive Principle:

Principle #31Porous materials

3Adaptability or versatility

If non-parallel mesh lines are used in the acellular dermal matrix sheet, then stretch capability in multiple directions is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvestretch directionVSAvoidmesh pattern fabrication

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The mesh pattern design achieves multiple functions simultaneously: it provides structural support, enables multidirectional stretch, and facilitates fluid drainage. This multi-functionality is achieved through a unified line arrangement that accomplishes all objectives without requiring separate manufacturing processes

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

There is disclosed a packaged allograft implant configured for implantation in a human recipient. In an embodiment, the packaged allograft implant includes an acellular dermal matrix sheet having a top surface and a bottom surface in opposition to one another, a perimeter surrounding the top surface and the bottom surface, and a thickness extending between the top surface and the bottom surface. The packaged allograft implant further includes a mesh pattern extending across at least a portion of the top surface and the bottom surface of the acellular dermal matrix sheet, the mesh pattern providing through-holes extending between the top surface and the bottom surface of the acellular dermal matrix sheet, and the mesh pattern having a plurality of mesh lines extending in a first direction and a second direction. The first direction and the second direction are orthogonal to one another so as to allow a given amount of stretch in each of the first direction and the second direction. Other embodiments are also disclosed.
