Segmented suture guides on a central hub enable running sutures and easy release, resolving interference with circumferential flanges.
Dynamic collapsible elements conform to irregular calcified valve annuli, eliminating paravalvular leakage gaps that rigid outer skirts cannot bridge.
A transcatheter delivery system reshapes the valve annulus through symmetrical cinching of tensioned implant members.
A segmented annuloplasty ring expands through a catheter to restore valve anatomy, reducing regurgitation without open heart surgery risks.
Reduced axial length prosthetic valves use ventricular and atrial anchors to minimize protrusion into heart chambers during implantation.
A titanium annuloplasty ring uses a waveform contour to adapt to dynamic cardiac motion.
Rotating corkscrew anchors attach annuloplasty rings to cardiac tissue, reducing mitral valve regurgitation without compressing the circumflex artery.
Rotating the anchor around native chordae secures the prosthetic valve while minimizing invasiveness.
Resilient followers capture valve leaflets while deforming to follow opening motion, avoiding bulky static clamps.
Acellular extracellular matrix cardiovascular prostheses promote tissue regeneration while reducing thrombosis and intimal hyperplasia.
Variable elasticity segments match native tissue expansion, resolving support versus compliance trade-offs.
Flexible membrane covering reduces fibrotic tissue reactions while porous metal mesh prevents blood stasis and thrombosis.
A winch-based annuloplasty ring enables post-operative dimension adjustment to resolve residual valvular insufficiency or stenosis risks.
A subannular support structure repositions mitral valve leaflets to improve coaptation and reduce regurgitation without open surgery.
