Annuloplasty Rings TRIZ Cases

Variable-thickness cores, slits, and expansion joints let an annuloplasty ring conform to a transcatheter valve and reduce regurgitation.

An outward-bulging outer sealing member helps prosthetic valves seal atraumatically against native tissue and minimize paravalvular leakage.

External commissure tab assemblies widen leaflet opening in small prosthetic valves, lowering pressure gradients and preserving coronary access.

A leaflet-locking anchoring member secures a mitral valve prosthesis without annular radial force, improving sealing and reducing displacement risk.

Anchored members and an adjustable tensile link reduce mitral annulus dilation and improve leaflet coaptation in catheter annuloplasty.

A coaptation member with multiple leaflet clips stabilizes mitral valve leaflets to reduce regurgitation with less tissue disruption.

A folded skirt lets the valve elongate axially during crimping, reducing tears, uneven attachment, and leaflet abrasion in transcatheter delivery.

A transformable leaflet clip uses tensioning members to improve valve coaptation, reduce regurgitation, and limit damage during implantation.

A catheter-delivered coaptation element with tissue anchors improves mitral leaflet sealing despite valve motion and can be retrieved or replaced.

Integrated retention units pierce valve tissue to secure a coiled annuloplasty ring, reducing suturing complexity and trauma in catheter repair.

A radiation-crosslinked hydrogel fabric layer cushions blood-cell impact on annuloplasty rings, reducing hemolysis and core fatigue.

Directional flexibility and rigidity in an annuloplasty ring reduce suture stress while guiding mitral annulus motion and limiting dilation.

A cooled tubular sheath inside curved introducers prevents implant teeth from sticking, scraping, and releasing particles during precise delivery.

A cord loop and pull-out connection unit let artificial chordae detach without cutting, improving implantation accuracy and reducing valve repair risk.

A spring-contracted mitral annuloplasty ring reshapes a dilated annulus through catheter delivery to improve leaflet coaptation with less invasive repair.

Rotating anchors and a threaded shaft let a catheter-delivered implant cinch a dilated mitral annulus with less invasive valve repair.

Dual pull wires and shaped distal sections help position a valve anchoring device accurately in complex mitral and tricuspid anatomy.

Preassembled commissure assemblies placed outside the frame help small prosthetic valves lower pressure gradients and preserve coronary access.

A ratcheting 3D annuloplasty ring enables post-implant mitral sizing adjustment on a beating heart to reduce reoperation and sizing errors.

A deformable clip arm expands at the valve to widen leaflet contact while staying compact enough for guide catheter delivery.

Curved arms and a leaflet capture region secure a posterior mitral valve while preserving annulus shape and reducing LVOT obstruction risk.

Atrial and ventricular bands clamp mitral valve leaflets by catheter delivery, avoiding open-heart surgery and reducing recovery burden.

An expandable catheter reshapes surrounding tissue and positions implants through one insertion, reducing multi-catheter complexity and patient risk.

Coiled support rings and a heating element simplify annuloplasty deployment, enable repositioning, and reduce detachment complexity and procedure time.

End connectors let a partial annuloplasty band become a full ring later, supporting TMVR or TTVR without repeat open-heart surgery.

End connectors allow a partial annuloplasty band to become a closed ring later, enabling TMVR/TTVR anchoring without repeat open-heart surgery.

Direct primary and secondary sutures form self-tightening leaflet attachments that avoid fabric ingrowth, lowering thrombus risk and regurgitation.

A mesh-and-pile sealing member conforms to annulus irregularities to cut paravalvular leakage without increasing crimped valve profile.

Varying strut and anchoring-leg geometry helps deliver and secure a mitral prosthetic valve while limiting chamber protrusion and tissue damage.

Varying coil cuts and pitch improve mitral valve anchoring, reduce paravalvular leakage, and maintain annulus sealing stability.
