Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional device for loading heart valve implants into delivery systems is used, then the implant can be loaded into the delivery system, but the operations required are complicated and increase surgery time
Solution Approach 1:
The loading device is divided into distinct functional components: a guide cap with conical section for initial implant reception and compression, a guider for positioning and guiding, and a delivery system for final implant deployment. This segmentation allows each component to perform its specific function efficiently, simplifying the overall loading operation and reducing surgical time.
Solution Approach 2:
The guide cap acts as an intermediary component between the implant and the delivery system. It provides a conical section that facilitates controlled compression of the implant and guides it into the delivery system, eliminating the need for complex manual manipulation and reducing surgical time.
2Device complexity
If traditional loading devices are used, then implant loading is possible, but the device structure becomes complex requiring intricate surgical maneuvers
Solution Approach 1:
The invention extracts and eliminates unnecessary complex components from traditional loading devices. By using a simplified guide cap with conical section, guider, and delivery system, it removes the need for intricate surgical maneuvers while maintaining effective implant loading capability.
Solution Approach 2:
Instead of using complex mechanisms to achieve implant compression and loading, the invention inverts the approach by using a simple conical section in the guide cap that naturally facilitates controlled compression through its geometry, eliminating the need for complex compression mechanisms.

AI summary
A guide cap and a loading system for loading an implant into a delivery system are disclosed which are capable of simplifying operations required in interventional surgery using the implant. The guide cap has a lumen passing therethrough and includes: a conical section; a straight or conical tube in communication with a small open end of the conical section; and a flange, wherein a large open end of the conical section flares outward and thereby forms the flange. The loading system includes a guider and the guide cap. During the process of loading the implant into the delivery system, the guide cap enables the valve prosthesis to be coupled to the connector of the delivery system and allows the valve prosthesis to be compressed so as to be entirely capsuled in the delivery system with relatively easy and quick operations, thereby reducing surgery time during its clinical use.
