Heart Valves TRIZ Cases

A lattice-cell frame separates prosthetic and native leaflets to reduce frictional wear while positioning arches prevent stent displacement.

Friction coupling anchors an expandable frame in the valvular annulus without penetrating anchors, simplifying artificial valve implantation.

Wedge members restrain commissure tab assemblies inside expandable valve-frame windows, simplifying leaflet mounting and limiting displacement during handling.

A robotic carriage interfaces with a catheter cable control assembly to improve precision during cardiac implant deployment.

Friction can threaten collapsed valve containment; a connecting ring and retainer control deployment without a separate introducer.

Multiple commissure bodies linked by suspension struts and eyelets distribute leaflet loads to support prosthetic valve sealing and anchoring.

A helical coil docking device creates an anchoring site for transcatheter valves, improving fit and reducing paravalvular leakage.

Movable offset elements adapt leaflet articulation across valve diameters, helping limit wear and pressure gradients in prosthetic heart valves.

Tensioned sutures control stent expansion and foreshortening, helping position, reposition, and retrieve a prosthetic heart valve.

Thinner inner yarns and thicker outer yarns in the woven skirt limit leaflet abrasion while supporting sealing and valve durability.

Clip mechanisms anchor a prosthetic coaptation member to native cardiac anatomy, enabling minimally invasive tricuspid repair with less leaflet disruption.

Expansion grooves and limiting structures let a polymer heart valve expand for valve-in-valve implantation without disrupting normal blood flow.

A split power-and-transmission cabin drives robotic adapters to improve surgical precision while reducing surgeon exertion and radiation exposure.

Alternating cuff-only and cuff-stent stitches reinforce the prosthetic valve edge, supporting sealing and reducing perivalvular leakage.

Existing mitral clips can hinder later transcatheter repair or replacement; catheter-delivered cutting separates them from leaflet tissue.

A deployable lever stabilizes and captures spaced mitral leaflets during transvascular edge-to-edge repair to reduce regurgitation.

Uneven locking forces can distort valve closure; coordinated wire lockers in a multi-lumen tube help maintain a regular repaired valve shape.

Variable-diameter funnel slots hold the valve and guide its transition from expanded storage into a delivery device.

An introducer catheter, delivery catheter, and hemostasis seal support precise valve deployment while limiting vascular trauma and complications.
