Heart Valves TRIZ Cases

Radial expansion anchors ECM valves to annuli, preventing suture failure and regurgitation under cardiac stress.

A stiffening ring snap-fits to a heart valve stent, securing the sewing cuff assembly with minimal radial thickness.

A dual valve prosthesis uses a stent and annular frame to laterally offset prosthetic valves for precise transcatheter deployment.

Replacing inflatable balloons with a self-expanding lattice shutter reduces implantation complexity and prevents balloon damage during mitral valve repair.

A catheter filter expands to trap embolic particles while allowing red blood cells to pass through.

Segmented reinforcement members and tacking stitching prevent leaflet-stent contact while maintaining frame mechanical performance.

Segmented positioning and retaining arches align the device precisely before deployment, preventing longitudinal displacement during cardiac cycles.

A one-piece outer skirt reduces the size of a prosthetic heart valve in its reduced-diameter delivery configuration.

Leaflets with aligned tension lines reduce deflection under load, addressing perivalvular leakage in patients with uneven calcification.

Segmentation and nesting principles create seamless ECM prosthetic valves that prevent perivalvular leakage while promoting host tissue regeneration.

Cusp interface loops engage native leaflets to anchor TAVI implants, preventing migration in unstable aortic lumens.
