Heart Valves TRIZ Cases
- Texturized Yarn Sealing Member for Prosthetic Valve Retention
A composite sealing member with texturized yarns promotes outward thrombus formation, preventing paravalvular leakage and tissue damage during expansion.
- Collapsible Shape Memory Frame for Cardiac Cell Construct Delivery
A collapsible shape memory frame expands to retain cardiac cell constructs around the heart.
- Segmented Capsule and Cinch Mechanism for Heart Valve Delivery
A delivery catheter uses a capsule segment and cinch mechanism to hold a heart valve prosthesis in a reduced diameter state.
- Valve Repair Device With Paddles And Expanding Spacer
A valve repair device uses movable paddles and an expanding spacer to attach to native heart tissue.
- Tricuspid Valve Support Device with Tilting Flow Optimizer
A tricuspid valve support device uses a tilting flow optimizer to seal regurgitant orifices during systole.
- Transvalvular Intraannular Band for Mitral Valve Repair
An arcuate transvalvular band reduces mitral regurgitation by displacing the central portion toward the left ventricle, advancing coaption timing.
- Prosthetic Valve Leaflet Reinforcement via Porous Polymer Infiltration
Porous reinforcing edges anchor the main polymer body, resolving uneven stress distribution and improving tear resistance at suture points.
- Heart Occlusion Device Self-Centering Waist and ePTFE Coverings
Shape memory wires form a self-centering waist that adapts to defect geometry, reducing thrombus formation through ePTFE coverings.
