AI Technical Summary
Technical Problem
Collapsible prosthetic heart valves face issues with inadequate coaptation of heart valve leaflets due to anatomical variations, leading to increased stresses and potential valve failure, and conventional delivery devices do not allow sufficient operability during partial deployment.
Method used
The leaflets are predominantly attached to a cuff rather than the stent struts, using a specific suturing pattern that maintains a distance from the struts and redistributes stress, allowing for better coaptation and flexibility.
Benefits of technology
This design reduces stress on the cuff, enhances durability, and allows for better anatomical adaptation, minimizing leakage and wear, while maintaining flexibility for partial deployment and testing.
