Solution Overview

Problem

Current muscle regenerative procedures face challenges such as excess inflammation, scar tissue formation, and muscle loss at donor sites due to the use of muscle transplants, and there is a need for improved methods to manage muscle repair, regeneration, and augmentation, especially for individuals with low muscle mass or those requiring increased strength or aesthetics.

Innovation Solution

Decellularized muscle matrices that retain some myofibers or myosin are used to create muscle implants, which can be in particulate or sheet form, allowing for controlled decellularization to maintain structural integrity and promote functional muscle regeneration, augmentation, and treatment of muscle defects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If muscle transplants are used for muscle repair and regeneration, then muscle mass can be restored, but excess inflammation and scar tissue formation occur

Engineering Contradiction:
Improvemuscle massVSAvoidinflammation and scar tissue
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and removes cells from muscle tissue while preserving the extracellular matrix and myofibers, creating a decellularized muscle matrix that maintains structural integrity and regenerative capacity without the inflammatory response associated with cellular muscle transplants

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The decellularized muscle matrix acts as an intermediary scaffold that provides structural support and biochemical signals for muscle regeneration without introducing foreign cells that would trigger immune rejection and inflammation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If muscle allografts are harvested from donor sites, then muscle repair can be achieved, but muscle loss occurs at the donor site

Engineering Contradiction:
Improvemuscle repair capacityVSAvoiddonor site muscle mass
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent creates a copy of the muscle extracellular matrix and myofiber structure without requiring live muscle tissue, using decellularized matrix that can be processed from non-donatable sources while preserving the regenerative template

Inventive Principle:
Principle #26Copying

3Object-generated harmful factors

If complete decellularization is performed to remove all cells, then immune rejection is reduced, but structural integrity and regenerative capacity are lost

Engineering Contradiction:
Improveimmune rejectionVSAvoidstructural integrity
Core Design Contradiction:
Object-generated harmful factorsVSStability of the object's composition

Solution Approach 1:

The patent applies selective decellularization that differentiates between cell types and locations, removing immunogenic cells while preserving myofibers and extracellular matrix structures that provide structural integrity and regenerative signals

Inventive Principle:
Principle #3Local quality

4Object-generated harmful factors

If enzyme treatment is increased to improve decellularization, then cell removal is enhanced, but myofiber retention decreases

Engineering Contradiction:
Improvecell removal efficiencyVSAvoidmyofiber content
Core Design Contradiction:
Object-generated harmful factorsVSQuantity of substance

Solution Approach 1:

The patent applies partial decellularization using controlled enzyme treatment that removes sufficient cells to reduce immunogenicity while stopping before complete decellularization to preserve myofiber content and structural integrity

Inventive Principle:
Principle #16Partial or excessive action
