Solution Overview

Problem

Three-dimensional tissue scaffolds lack adequate structural integrity to securely anchor surgical anchors, leading to potential migration or deformation of the implant, especially in aesthetically significant areas like the breast.

Innovation Solution

A composite tissue product anchor bolster system comprising a tissue scaffold securely coupled with an anchor bolster, which can be shaped as a tab, ribbon, or combination thereof, to provide enhanced anchoring capabilities to anatomic structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a three-dimensional tissue scaffold is used, then tissue regeneration and minimal inflammatory response are promoted, but structural integrity and anchoring capability are insufficient

Engineering Contradiction:
Improveanchoring capabilityVSAvoidstructural integrity
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent combines a tissue scaffold with an anchor bolster into a composite structure. The anchor bolster is securely coupled to the tissue scaffold, creating a unified device that integrates the regenerative properties of the scaffold with the anchoring strength of the bolster. This merging resolves the contradiction by allowing both tissue regeneration and secure anchoring to occur simultaneously through the combined structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention uses a composite tissue product consisting of two distinct components: a tissue scaffold (which may be acellular dermal matrix, acellular adipose matrix, or acellular muscle matrix) and an anchor bolster (which may be acellular dermal matrix or synthetic product). This composite structure leverages the complementary properties of each material to achieve both biological compatibility and mechanical strength.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If the tissue scaffold is made softer to reduce inflammatory response, then biocompatibility improves, but ability to securely anchor surgical anchors deteriorates

Engineering Contradiction:
Improveinflammatory responseVSAvoidanchoring strength
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The device is segmented into two functional zones: the tissue scaffold portion that contacts and integrates with host tissue (minimizing inflammation), and the anchor bolster portion that provides structural support for anchor insertion and anchoring (providing strength). This segmentation allows each component to be optimized for its specific function without compromise.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the composite device have different properties tailored to their specific functions. The tissue scaffold region has soft, biocompatible properties to reduce inflammatory response, while the anchor bolster region has enhanced structural properties to securely anchor surgical anchors. This local differentiation resolves the contradiction by applying appropriate material characteristics where needed.

Inventive Principle:
Principle #3Local quality

AI summary

The present disclosure provides anchor bolsters for three-dimensional biologic scaffolds, including related methods of formation and use. The composite bolster-scaffold provides an improved device to securely anchor a three-dimensional tissue scaffold in position relative to surrounding anatomic structures, allowing time for colonization of native cells and subsequent incorporation of the three-dimensional tissue scaffold by the recipient tissue bed.
