Interventional Valve Protection and Loading Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interventional valve systems require complex devices for protection and loading, especially for half-loading pre-mounted systems, which complicates operation and increases device requirements.
Innovation Solution
A protection and loading device comprising a first protector, a second protector, and a third protector that cooperate to form an accommodating cavity, allowing the valve to be protected during transport and easily loaded by changing the relative position of the protectors, simplifying the operation and structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a half-loading pre-mounted valve system is used, then the valve can be pre-mounted on the delivery system, but the protection and loading devices become more complex and require higher device requirements
Solution Approach 1:
The patent combines the protection function and loading function into a single integrated device structure. The first protector encompasses both the valve and the loading mechanism, merging what would traditionally be separate protection and loading devices into one unified system, thereby reducing overall device complexity while maintaining pre-mounted capabilities
Solution Approach 2:
The protection and loading device is divided into functional segments: the first protector for encompassing the valve, the second protector for compression, and the third protector for fixation on the distal rod body. This segmentation allows each component to perform its specific function efficiently while simplifying the overall structure compared to traditional integrated systems
2Reliability
If traditional protection devices are used, then the valve is protected during transport, but the loading operation becomes complex and time-consuming
Solution Approach 1:
The valve is pre-mounted on the delivery system within the first protector before transport. The protectors are pre-configured in a protective state that automatically transitions to a loading state through simple relative movement, eliminating the need for complex loading procedures and reducing operation time while maintaining protection integrity
Solution Approach 2:
The device transitions dynamically between two states: a protective state during transport where the first protector encompasses the valve, and a loading state where the protectors move relative to each other to enable valve loading. This dynamic state transition simplifies operation by eliminating manual reconfiguration steps
3Reliability
If multiple protectors are used for comprehensive protection, then the valve is well-protected, but the device structure becomes more complex
Solution Approach 1:
The first protector encompasses the valve and contains the second protector within its structure. The third protector nests on the distal rod body and cooperates with the first protector. This nested arrangement provides comprehensive protection through multiple layers while maintaining a compact and simplified overall structure compared to separate protection devices

AI summary
A protection and loading device for an interventional valve system is provided. The interventional valve system includes a valve and a delivery system. The valve is fixed on a distal rod body of the delivery system. The protection and loading device includes: a first protector, a second protector, and a third protector. The first protector is located at a front end of the distal rod body and encompasses a half of the valve. The third protector is configured to fix and sleeve on the distal rod body. In a protection state, the first protector cooperates with the third protector at the first position. In a state of valve loading the first protector cooperates with the third protector at the second position.
