Heart Valves TRIZ Cases

Leaflet panels nested within stent cells reduce valve profile while improving sealing against paravalvular leaks during deployment.

A helical docking coil and expandable guard anchor prosthetic valves in non-circular native valves to limit paravalvular leakage and instability.

A coiled guidewire with an opposite reverse curve helps withdraw the delivery device without contacting or shifting the heart valve implant.

A releasable docking station with prongs, grooves, and tabs secures a ventricular assist device for stable anchoring and easier replacement.

A cuff-led leaflet attachment improves coaptation, spreads stress, and reduces leakage and wear in collapsible prosthetic heart valves.

A porous mitral valve spacer with movable anchors reduces regurgitation while lowering leaflet stress and easing implantation.

Staged sheath release enables precise mitral valve positioning and recapture while reducing trauma and preserving native leaflet function.

A movable inner tube opens and protects hemostatic seals, allowing crimped valve catheters to pass without a separate loader or seal damage.

Retention elements clamp folded bridge loops to spread repetitive leaflet loads, reducing mounting-edge stress and valve fatigue.

Dual anchors and compliant sealing elements help prosthetic valves fit oval native annuli, secure leaflets, and reduce paravalvular leakage.

Movable frame portions and leaflet anchoring improve native heart valve sealing while enabling minimally invasive transvascular repair.

A strut-based locking member holds an expandable prosthetic valve at selected diameters, enabling controlled deployment and repositioning.

Movable paddles and barbed clasps capture mitral leaflets to maintain a seal under systolic pressure while avoiding open surgery.

Asymmetric stent struts and a suspended valve frame keep the valve round in bicuspid anatomy, improving coaptation and limiting leaks.

Bridging skirt trenches guide blood into the inner frame of a prosthetic heart valve to limit stagnation and clotting risk in atrial use.

A deformable polyurethane sealing skirt adapts during delivery and deployment to reduce perivalvular leakage and skirt damage.

Folded leaflet tabs and reinforcing members simplify prosthetic heart valve commissure assembly while preserving attachment strength and stiffness.

Radiopaque inflow and outflow markers help align a transcatheter valve with native commissures and improve placement under 2D X-ray imaging.

A crown piece with top and bottom cuffs helps a heart valve deploy on a foldable stent with precise positioning, secure attachment, and MRI compatibility.

Radiopaque markers and a shape-changing indicator arm give real-time feedback on prosthetic valve expansion and locking during implantation.

A conformable coaptation element improves mitral leaflet sealing through catheter delivery, reducing regurgitation with less invasive treatment.

Folded overlapping leaflet tabs secured to a protruding attachment member reduce cyclical stress, limiting commissure wear and displacement.

Independent ring-gear transmissions enable remote catheter operation, reducing doctor skill burden and radiation exposure during guided procedures.

Leaflet-based asymmetric fixation stabilizes a tricuspid prosthetic valve without annular attachment, reducing trauma and conduction risk.

A narrowed bending section and variable diameter gripper cut deployment pulling force while improving fatigue resistance and control line safety.

A self-expanding annular scaffold and membrane seal irregular gaps around transcatheter valves to reduce paravalvular leakage.

Dual transmission assemblies enable remote catheter operation during mitral regurgitation procedures, reducing radiation exposure and operator skill burden.

Flexible guide fingers preset valve leaflet folding during crimping, reducing delivery profile while limiting leaflet damage.
