Mitral Valve Sealing Assembly for Fast Leaflet Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatments for mitral regurgitation, such as surgical stitching and catheter-delivered clips, are inadequate as they either require extensive operation time or create stress on patient leaflets, and there is a need for improved devices and methods to treat this condition.
Innovation Solution
An implantable prosthetic device with a coaption element and anchoring means, featuring moveable paddles and barbed clasps, is designed to be deployed via a delivery sheath, allowing for secure capture and sealing of native heart valve leaflets, reducing regurgitation by anchoring between the leaflets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical stitching is used to treat mitral regurgitation, then the valve can be repaired, but the operation time is extensive
Solution Approach 1:
The invention extracts the complex surgical stitching process by providing a pre-formed coaption element that can be delivered via catheter. The coaption element is a self-contained structure with integrated anchoring features (paddles and clasps) that eliminates the need for time-consuming surgical stitching while maintaining valve repair effectiveness
Solution Approach 2:
The coaption element serves as an intermediary device that bridges the gap between surgical and percutaneous approaches. It provides surgical-level repair capability through a percutaneous delivery system, acting as a mediator that combines the advantages of both approaches while avoiding their disadvantages
2Ease of operation
If catheter-delivered clips are used to treat mitral regurgitation, then the procedure is less invasive, but stress is created on patient leaflets
Solution Approach 1:
The coaption element is segmented into multiple functional components: the coaption portion for sealing, multiple paddles for distributed anchoring, and multiple clasps for secure leaflet capture. This segmentation distributes the mechanical load across multiple attachment points rather than concentrating stress at a single clip location, reducing harm to the leaflets while maintaining procedural minimality
Solution Approach 2:
The paddles are designed to be moveable from a closed position to an open position, allowing the device to adapt dynamically to the valve anatomy during deployment. This dynamic capability enables optimal positioning and load distribution, reducing stress on the leaflets while maintaining secure anchoring
3Reliability
If multiple clips are used on the commissures, then leaflet capture is improved, but operation time increases
Solution Approach 1:
The invention merges multiple leaflet capture functions into a single integrated coaption element with multiple paddles and clasps. This unified structure achieves reliable leaflet capture at multiple locations simultaneously through one deployment action, eliminating the need for sequential clip placement while maintaining comprehensive leaflet engagement

AI summary
An implantable prosthetic device includes a coaption portion, paddles, and clasps. The paddles are moveable from a closed position to an open position. The clasps are also moveable from an open position to a closed position. The implantable prosthetic device can be used to repair a naitive valve, such as a native mitral valve.
