Heart Valves TRIZ Cases
- Multi-Part Prosthetic Valve Frames With Bridging Covers for Emboli Reduction
Annular groove covers bridge separated valve-frame sections to smooth flow, reduce emboli, and support catheter delivery.
- Collapsible Gasket Seal for Mitral Valve Paravalvular Leakage
An hourglass anchor and collapsible gasket seal the native mitral annulus while keeping the prosthetic valve compact for delivery.
- Heart Valve Sealing Devices for Minimally Invasive Regurgitation Control
Coaption elements fill gaps between damaged valve leaflets, while catheter delivery enables minimally invasive implantation to reduce regurgitation.
- 3D Catheter Trajectory Planning for Transseptal Mitral Valve Delivery
Digital anatomy reconstruction simulates catheter paths before transseptal mitral valve delivery, reducing catheter changes, procedure time, and radiation exposure.
- Collapsible Heart Pump With Flexible Guides for Minimally Invasive Insertion
Modular cardiac assist components assemble in the pericardial space to preserve structural integrity and support customized heart filling and emptying forces.
- Prosthetic Heart Valve Deployment for Smaller Catheter Profiles
Multiple control wires and a retrieval catheter enable recapture while reducing delivery size for minimally invasive valve implantation.
- Tiltable Prosthetic Valve Delivery Assembly for Annulus Alignment
Unequal locking-element lengths tilt the prosthetic valve on its catheter for precise native-annulus alignment and repositioning.
- U-Shaped Embolic Filter Frames for Continued Blood Flow
U-shaped filter frames capture debris during catheter-based valve procedures while allowing blood flow to continue and reducing embolic risk.
- Sun-and-Planet Gear Adapter for Mitral Valve Sheath Control
The sun-and-planet gear adapter drives continuous sheath rotation and bending for precise mitral valve device delivery.
- Replacement Valve Delivery With Tethered Recapture and Repositioning
Multiple tethers and engagement pins help recapture or reposition a replacement valve after deployment during minimally invasive delivery.
- Percutaneous LAA Occlusion Device With Segmented Retention
Segmented flanges and a catheter-delivered, self-expanding structure improve LAA retention while supporting rapid occlusion and precise positioning.
- Percutaneous Catheter-Directed LAA Occlusion With Flexible Segments
A flexible transition segment links self-expanding Nitinol portions to support catheter delivery, retention, and LAA occlusion in less than 10 minutes.
