Heart Valves TRIZ Cases

An asymmetric heart valve prosthesis adapts to the non-circular aorta shape using flexible leaflets with varying opening angles and convex curvatures.

Solidifying bags expand outside the heart to pull walls together, avoiding invasive sternotomy for dilated cardiomyopathy treatment.

A single expandable sizer replaces multiple discs, reducing surgery time while the protective cover prevents tissue damage and entanglement.

Nested transcatheter valves expand from compressed states to treat tricuspid defects, resolving size constraints in minimally invasive procedures.

An implantable sprayer circulates blood through the left atrial appendage via an arterial shunt.

A transcatheter anchor support integrates a lock cap, tether swivel, and cone to secure medical prostheses.

Hooks and a check valve anchor a valved stent, preventing peripheric valvular leaks during mitral replacement.

A heart valve deployment instrument uses a segmented drive member to axially displace two independent elements for controlled prosthesis expansion.

Fluid pressure tensions pericardial tissue during chemical treatment, resolving waste from non-uniform processing.

Polymeric valves with calcium inclusions replicate human calcific conditions, enabling accurate transcatheter valve testing without complex animal models.

A heart valve simulator uses segmented arms to adjust papillary muscle positions for realistic ventricular movement.

An adjustable bend catheter navigates complex anatomy to position a prosthetic valve, preventing perivalvular leaks caused by rigid frame mismatches.

A prosthetic valve delivery catheter uses a circumferentially indexed fit between its capsule and anchor to enable precise rotational alignment.

Heart-shaped commissural posts and oval intercommissural openings balance structural strength with tissue flexibility to prevent stent failure.
