Annuloplasty Rings TRIZ Cases
- Prosthetic Valve Markings for Implant Alignment
Visible markings on prosthetic heart valve frames guide accurate orientation during minimally invasive implantation.
- Wire Annuloplasty Ring Mitral Valve Leaflet Coaptation
A wire and anchor assembly exerts radial force to compress the mitral valve annulus.
- Segmented Annuloplasty Device with Pawl Locking
Segmented annuloplasty devices use interlocking teeth and pawls to cinch tissue via a pull wire, preventing ring migration during post-procedural dilation.
- Subvalvular Support Device for Mitral Valve Leaflet Tethering
Anchoring to the ventricular wall, a subvalvular support device holds a tethered valve leaflet to restore coaptation without removing tissue.
- Apical Mitral Valve Translocation Device
A ring-shaped device translocates the native mitral valve toward the heart apex to restore coaptation geometry.
- Controllably Expandable Annuloplasty Structure for Variable Annulus Sizing
Control wires expand flexible segments of an annuloplasty structure to fit variable annulus sizes without pre-measurement.
- Adjustable Annuloplasty Ring with Deployable Pressing Elements
Deployable pressing elements deform an adjustable annuloplasty ring to customize shape and size, reducing residual regurgitation risk.
- Minimally Invasive Heart Valve Prosthetic Device
An insert member creates a tight seal between valve leaflets to prevent regurgitation without open-heart surgery.
- Mitral Valve Inversion Prostheses Annulus Reshaping
Transcatheter delivery system replaces open-heart surgery risks by reshaping the mitral valve annulus via expanding helical anchors.
- Annuloplasty Devices with Varying Anterior-Posterior Ratios
Segmented rigid and flexible portions accommodate unique mitral valve anatomy, resolving the trade-off between structural support and leaflet motion.
- Fatigue Testing Device for Annuloplasty Rings Using Cam Mechanism
A fatigue testing device applies cyclic loads to annuloplasty rings using a cam mechanism that transforms rotary motion into linear reciprocating force.
- Prosthetic Mitral Valve Self-Expanding Anchor
A prosthetic mitral valve uses a self-expanding anchor to secure the device within the heart.
- Adjustable Valve Annulus Remodeling Device
An adjustable heart valve device uses a dynamic mechanism to alter ring and elongate member dimensions, preventing recurring ventricular remodeling.
- Prosthetic Aortic Valve Self-Anchoring via Bulging Struts
Connecting struts bulge into the valsalva sinus to secure anchoring while avoiding coronary artery occlusion.
- Single Leaflet Prosthetic Valve for Mitral Regurgitation
A prosthetic heart valve with a single leaflet and collapsible anchoring structure.
- Removable Coronary Sinus Displacement Unit for Mitral Valve Repair
A flexible elongate displacement unit modifies mitral valve annulus shape via a reversibly expandable proximal portion and distal anchoring segment.
- Pre-shaped Template for Heart Valve Annulus Reshaping
Rotatable anchors embed into tissue to draw the annulus into a concavity, reducing regurgitation and minimizing device migration.
- Elliptical Intra-Annular Frame for Aortic Valve Repair
An elliptical intra-annular mounting frame with flaring posts supports aortic valve cusps.
- Transfemoral Mitral Valve Annuloplasty Device
A transfemoral device deploys pivotally connected arms to anchor a reinforcement ring on the mitral valve.
