Prosthetic Heart Valve Packaging Anti-Rotation Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging systems for prosthetic heart valves do not facilitate easy removal of the valve using a surgical handle, posing a challenge for medical practitioners during procedures.
Innovation Solution
A packaging assembly featuring a jar with inwardly-directed rails and a packaging sleeve with protrusions that create an anti-rotation interference, allowing the valve holder to be securely attached and enabling easy attachment of a delivery tool, thereby stabilizing the valve and allowing for controlled removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a packaging sleeve is used to stabilize the valve within the jar, then the valve is protected from damage, but the valve becomes difficult to remove using a surgical handle
Solution Approach 1:
The packaging system is divided into separable components: the packaging sleeve that stabilizes the valve during storage, and the surgical handle that attaches to the valve holder. The valve holder itself is a separate component that couples to both the sleeve and the surgical handle, enabling easy removal while maintaining protection during storage
Solution Approach 2:
The valve holder acts as an intermediary component between the packaging sleeve and the surgical handle. It provides a coupling mechanism that allows the surgical handle to attach to the valve assembly, facilitating easy removal from the jar while the sleeve remains in place to protect the valve during storage and transport
2Reliability
If the valve holder is securely attached to the packaging sleeve, then the valve is stabilized, but the attachment mechanism becomes complex
Solution Approach 1:
The valve holder combines multiple functions into a single component: it attaches to the packaging sleeve to provide stabilization during storage, and simultaneously provides a coupling interface for the surgical handle to enable easy removal. This merging of functions reduces the need for separate complex attachment mechanisms while achieving both stabilization and ease of operation

AI summary
Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a sterile jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. A delivery handle on the end of a shaft couples with the valve holder while the packaging sleeve engages the jar to prevent rotation. The assembly of the packaging sleeve, valve, and holder can then easily be removed from the jar.
