Annuloplasty Rings TRIZ Cases

An adjustable heart valve repair device uses an inflatable frame to conform to patient anatomy.

Integrating sensors into heart valve housing isolates monitoring electronics from blood flow, reducing thrombosis risks caused by direct contact.

A transvalvular intraannular band expands within the heart valve annulus to enhance leaflet coaptation, reducing regurgitation without open surgery.

Segmented sleeve design prevents anterior annulus dilation while maintaining posterior contraction for stable valve coaptation.

Segmented infra-annular supports stabilize the left ventricle to prevent recurrence of mitral regurgitation caused by ventricular dilation.

A shape memory support member conforms to the heart valve annulus upon activation.

Segmented annuloplasty ring transitions from elongate insertion geometry to rigid annular shape, enabling secure anchoring without open-chest surgery.

A stabilizing ring transitions to an annular geometry with anchors to secure prosthetic valves in compliant tissue, preventing position instability.

A heart valve repair device uses an annular base and elongated members to secure leaflet commissures.

An implantable anchor unit with a locking mechanism stabilizes the valve annulus while a coupling unit attaches leaflets for improved coaptation.

Deflectable guide catheters convey wires to a capture basket, resolving chordae tendineae navigation complexity.

Snap-fit inner and outer rings capture sutures between components, enabling accurate sizing while reducing surgical labor.

Resilient clip legs spring back from a compressed delivery shape to pierce tissue and anchor an annuloplasty implant, reducing procedural time.

An asymmetrical mitral prosthesis mimics native anatomy using flexible leaflets, resolving rigid device limitations that impair hemodynamic performance.

Asymmetric unilateral clamping prevents valve leaflet stenosis while effectively blocking regurgitation flow.

An adjustable sleeve with contracting members tightens the dilated mitral valve annulus, resolving regurgitation caused by ventricular enlargement.

Nitinol struts redirect pressure energy to enhance ventricular vortex formation and systolic ejection efficiency in dilated cardiomyopathy.

Segmented coil anchoring adapts to unique mitral anatomy, preventing paravalvular leakage and ventricular migration during percutaneous delivery.

Asymmetric tubular frame angles distal section inwardly to expand the annuloplasty device end while coupled to a delivery catheter.
