Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for transferring fat or other tissue from one location in a patient's body to a syringe for reinjection are clumsy, inefficient, and expose the tissue to ambient air, leading to waste and inconvenience.
Innovation Solution
A modular tissue collection apparatus featuring a manifold structure with interconnected syringe barrels and a vacuum system that allows for sequential filling of syringes with tissue, minimizing exposure to air and improving the efficiency of the fat transfer process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional systems are used to transfer tissue to syringes, then the process is simple, but the tissue is exposed to ambient air causing waste and reduced take rate
Solution Approach 1:
The system maintains a closed environment where tissue is transferred through fluid pathways without exposure to ambient air. The syringe filling apparatus creates a controlled environment that prevents air contact with the harvested fat, thereby reducing tissue waste and improving graft take rate.
2Productivity
If conventional transfer methods are used, then the equipment is simple, but the process is clumsy and inefficient
Solution Approach 1:
The system combines the harvesting cannula, transfer pathways, and syringe filling apparatus into an integrated modular system. This merging of components eliminates the need for separate transfer steps and manual handling, thereby improving both efficiency and ease of operation during the fat transfer process.
Solution Approach 2:
The system introduces a closed fluid pathway as an intermediary medium between the harvesting cannula and syringe. This intermediary allows tissue to be transferred efficiently without direct manual handling, reducing mess and improving operational convenience while maintaining sterility.
3Loss of substance
If conventional systems are used, then the setup is simple, but tissue waste and mess are created
Solution Approach 1:
The closed system creates a controlled environment that prevents tissue exposure to ambient air throughout the transfer process. This eliminates the need for complex protective measures while minimizing tissue waste through efficient, contamination-free transfer to syringes.
Solution Approach 2:
The system enables continuous transfer of tissue from harvesting to syringe filling without interruption or exposure to air. The closed pathways allow uninterrupted flow of tissue, minimizing waste and reducing the complexity of manual transfer steps.

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 modular system enables efficient collection and transfer of tissue with reduced waste and mess, improving the 'take' rate of fat grafts by protecting the tissue from air and facilitating convenient handling and reinjection.
Implementation Method 1
A second manifold cap that includes a connector for interconnecting the apparatus to a vacuum source can be joined to the outlet of the last manifold element. Tissue is drawn through the inlet by a vacuum from the vacuum source.
Implementation Method 2
Tissue is drawn through the inlet by a vacuum from the vacuum source

AI summary
Tissue collection systems and methods are provided. More particular, a modular system including one or more manifold elements is provided. Each manifold element includes a manifold barrel and a coupler to which a syringe body can be connected. An inlet of a first manifold element is connected to a first manifold cap having an inlet orifice. A second manifold cap having an outlet orifice is connected to the outlet of the first manifold element or to the outlet of a second manifold element. The manifold barrel can include a barrel inlet that is offset from a barrel outlet.
