Heart Valves TRIZ Cases

Guidewires and locking clips position plates to secure tricuspid leaflets, reducing regurgitation through minimally invasive delivery.

Analyze medical signals to time cardiovascular device deployment accurately.

Nitinol-based leaflet sections and engaging members adjust leaflet geometry to improve closure and reduce cardiac valve regurgitation.

A flexible support, C-shaped retainer, and leaflet-engaging arms enable percutaneous mitral valve anchoring while limiting distortion.

Segmented linkages shift a compressed valve prosthesis into an arcuate form for minimally invasive luminal delivery.

A guide catheter separates the delivery system from implant components during crimping, reducing tears and punctures.

A catheter assembly combines electrosurgery, spaced distal marking, and one-handed sheath actuation for precise prosthesis deployment.

This case combines a single safety button with catheter alignment feedback for controlled, one-handed prosthesis deployment.

A foldable two-part frame uses cloth wrapping instead of sutures at leaflet flexing areas, supporting durable prosthetic valve deployment.

A transvascular valve repair device uses paddles, a spacer, and leak extensions to limit regurgitation without open-heart surgery.

Cloth-wrapped leaflet attachment reduces stress and abrasion during valve deployment.

Independent clamping stages use chordae tendineae to stabilize a mitral valve prosthesis and reduce regurgitation during deployment.

An expandable stent frame simplifies heart valve assembly and supports valve-in-valve procedures.

A catheter-delivered LAA occlusion device combines external and internal segments, Nitinol self-expansion, and thrombogenic layers.

See how layered, flexible sealing around a collapsible valve frame supports low-profile delivery while reducing paravalvular leakage.

Multiple anchors and a tensioned sleeve reshape the dilated heart to reduce mitral regurgitation and support cardiac output.

A threaded delivery assembly controls radial valve expansion, protects soft components, and enables clean separation after sizing.

A suture loop secures the skirt to the expandable frame, distributing diastolic loads to reduce leaflet stress and assembly effort.

A layered expandable sheath expands locally for large prosthetic devices while maintaining length and reducing vessel trauma.

This case uses separate inner and outer stent walls to preserve anchoring and sealing while supporting collapsible transcatheter delivery.

This case uses passive or powered valve movement triggered by blood pressure thresholds to improve circulation and oxygen supply.

A fluoropolymer membrane and elastomer composite controls leaflet bending, reducing stress, creases, peeling, and delamination.

A strip-formed expandable cage combines catheter flexibility with axial stiffness for secure atrial anchoring.

A compliant balloon and adjustable frame conform to complex paravalvular leaks while locking the device for stable sealing.

This case uses ventricular-side support and anchoring to restore leaflet coaptation while preserving mobility in regurgitant valves.

Cutouts and beams let the packaging clip deform elastically, securing the valve holder while easing insertion and removal.

This prosthesis system uses a detachable shaft channel to constrain and release the control wire, reducing manufacturing complexity.

A kinked, selectively insulated wire lacerates heart valve leaflets and helps prevent LVOT or coronary obstruction.

This valve case uses a flush dihedral guard and leaflet slot to limit over-rotation, leakage, and hinge stress.

A plastically deformable middle region adjusts passage diameter while expandable ends anchor the shunt within heart walls.

Explore a scalloped prosthetic valve frame using a cloth wrap to secure leaflets through compression and expansion with less abrasion.
