Heart Valves TRIZ Cases

Pivotable clamp arms on a control rod anchor a stented valve to irregular mitral or tricuspid geometry, resolving fixation security risks.

Nitinol atrial cage anchors valves at the AV junction, eliminating long-term foreign body presence through controlled resorption.

Glutaraldehyde cross-linked extracellular matrix tissue resists calcification and enables host regeneration without anticoagulation therapy.

Automated die-cut system maps pericardial tissue thickness to cut uniform heart valve leaflets, eliminating manual measurement errors.

A resilient spring collar supports a sewing ring above the annulus, allowing compression to improve anatomical fit and reduce hemodynamic mismatch.

A recoverable self-expanding valve uses a segmented tubular frame to anchor securely in the aorta.

A fixation device stabilizes a blood pump conduit within the aortic valve orifice using a radial support ring.

Axial fixation members sandwich the native valve complex, reducing embolism risk and leakage without high radial expansion.

Frame projections and restraining members secure leaflets via mechanical interlocking, preventing decoupling in aqueous environments.

Severing existing valve leaflets prevents coronary artery obstruction during repeat transcatheter aortic valve replacement procedures.

An integral heart valve clamp merges fixed and clamping arms to prevent disconnection during transcatheter repair.
