Annuloplasty Rings TRIZ Cases

Flexible socket structures mediate movement between implantable components, limiting abrasion while promoting tissue ingrowth and reducing thrombosis.

Ventricular anchors capture native leaflets while an atrial seal limits leakage during catheter-based mitral valve replacement.

The coiled support rings and retention units address difficult valve positioning and fixation without time-consuming suturing.

Thinner, wider mitral annuli complicate valve fixation; a coiled docking station creates stable anchoring and limits paravalvular leakage.

Helical wires anchor across the dynamic mitral annulus, creating a stable landing zone for staged prosthesis delivery and perivalvular sealing.

Remote cinching enables post-implant mitral ring sizing under echocardiographic guidance, reducing residual regurgitation and reoperation.

A catheter-delivered tubular implant uses rotatable helical anchors to reshape the mitral annulus and reduce regurgitation without open-heart surgery.

Rotating chord-manipulation arms reduce the annulus before ring implantation, supporting a durable seal while limiting invasive valve repair.

Permanent tricuspid regurgitation treatment can overload the right ventricle; a temporary pulmonary artery tool tests this risk first.

Biodegradable connectors hold an expanded frame after implantation, then release shape-memory contraction to resize the tricuspid annulus gradually.

Biodegradable connectors hold a larger ring diameter until tissue ingrowth, then release shape-memory contraction to reshape the tricuspid annulus.

A compressible, self-expandable multi-part frame uses ventricular anchors to support minimally invasive mitral valve replacement.

Catheter delivery combines deployable anchors and synthetic leaflets to position an annuloplasty ring and reduce mitral or tricuspid regurgitation.

Annular anchoring supports an adjustable axisymmetric mitral seal that improves coaptation without constricting native leaflet motion.
