Wound Packing with Multi-Potent Cells and Collagen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for chronic wounds, such as those experienced by individuals with diabetes or poor blood flow, are often ineffective or slow, leading to prolonged recovery times and potential amputation, highlighting the need for improved wound healing methods.
Innovation Solution
A wound packing system comprising multi-potent cells, plasma, and collagen, optionally with skin seeds and a protective barrier, is applied to the wound to promote healing, where the components are combined and shaped to fit the wound, and thickened with agents like thrombin to form a cohesive packing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional treatments and bandages are used for chronic wounds, then the wound may eventually heal, but the healing process is relatively slow and treatment time is extended
Solution Approach 1:
The wound packing is prepared in advance with multi-potent cells, plasma, and collagen components pre-combined and activated before application to the wound. This preliminary preparation ensures that regenerative factors are immediately available upon contact with the wound bed, eliminating the need for gradual introduction of healing agents and significantly accelerating the initial healing phase.
Solution Approach 2:
The invention combines multiple biologically active components (multi-potent cells, plasma, collagen, and thickening agents) into a single composite wound packing material. This composite structure provides synergistic effects where each component contributes different functions: cells provide regenerative capacity, plasma provides growth factors, collagen provides structural framework, and thickening agents provide gel formation. This multi-component composite accelerates healing beyond what single conventional treatments can achieve.
2Reliability
If conventional wound treatments are applied, then the wound may close over time, but the process is prolonged and may require extensive medical intervention
Solution Approach 1:
The wound packing is designed to be self-sustaining and self-regulating. The multi-potent cells within the packing continuously differentiate and regenerate tissue without requiring external intervention. The plasma and collagen matrix provide a self-contained environment that maintains moisture and delivers growth factors autonomously. This self-service capability ensures consistent healing progression without frequent medical visits or adjustments, significantly improving healing productivity.
Solution Approach 2:
The invention fundamentally changes the biochemical parameters of the wound environment by introducing activated plasma and growth factors that alter the healing kinetics. The thickening agents transform the physical state from liquid to gel, creating optimal conditions for cell proliferation. These parameter changes accelerate the healing rate from weeks/months to days/weeks, directly improving productivity while maintaining reliable wound closure.
3Ease of operation
If simple bandages and ointments are used, then the treatment is easy to apply, but the effectiveness at treating chronic wounds is relatively low
Solution Approach 1:
The wound packing system is segmented into modular components that can be prepared separately and then assembled: multi-potent cells, plasma, collagen, and thickening agents can be prepared in separate vials or compartments and then combined directly at the wound site. This segmentation maintains ease of application while incorporating advanced therapeutic components that significantly improve chronic wound treatment effectiveness compared to simple monolithic bandages.
Solution Approach 2:
The collagen and plasma matrix serve as intermediaries that bridge the gap between simple application and complex therapy. These materials provide a carrier medium that delivers multi-potent cells and growth factors to the wound bed in a controlled manner. The intermediary matrix simplifies the application process (similar to applying an ointment) while simultaneously providing the complex biochemical environment needed for effective chronic wound healing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The wound packing system accelerates wound closure and healing by utilizing the regenerative properties of multi-potent cells and plasma, potentially reducing recovery time and the risk of complications like amputation.
Implementation Method 1
thrombin, calcium chloride, one or more serine proteases, and/or any other suitable thickening agent or agents are combined with the multi-potent cells, plasma, and/or collagen to coagulate, gel, and/or otherwise harden the components to form a wound packing
Implementation Method 2
thrombin, calcium chloride, one or more serine proteases, and/or any other suitable thickening agent or agents are combined with the multi-potent cells, plasma, and/or collagen to coagulate, gel, and/or otherwise harden the components

AI summary
Methods for treating a wound with a wound packing are discussed. While the wound packing can include any suitable component, in some cases, it includes a collection of multi-potent cells (e.g., cells from bone marrow, amniotic membrane tissue, amniotic fluid, stem cells, etc.), plasma (e.g., concentrated and/or platelet rich plasma), and collagen (e.g., native and/or organized reconstituted collagen). In some cases, the wound packing is gelled, coagulated, or otherwise hardened through the use of thrombin, calcium chloride, and/or another suitable additive. In some cases, the wound packing is shaped to substantially correspond to the wound's shape. While the wound packing can be used in any suitable manner, in some instances, it is applied to the wound, skin fragments are applied to the packing, the packing is secured to the wound, and/or the packing is covered with a protective barrier. Other implementations are also described.
