An expansible helical anchor secures a mitral valve prosthesis, adapts to annulus size variation, and helps prevent paravalvular leaks.
A blood-swelling hydrophilic skirt improves prosthetic heart valve apposition to irregular tissue and helps mitigate paravalvular leakage.
Multiple seal positions and liquid-gas sterilization keep a wet-stored prosthetic heart valve moist while sterilizing hard-to-reach seal areas.
A collapsible capsule retracts into an outer stability shaft to shorten lever-arm steering error and improve prosthetic valve positioning.
A dual sterile barrier lets gas sterilization reach dry heart valves while blocking oxygen to prevent oxidation and structural damage in storage.
Outward protrusion arms reposition lacerated valve leaflets during implantation to keep coronary arteries clear and improve placement safety.
A steerable catheter deploys a leaflet-augmenting implant to close the regurgitant gap while preserving diastolic inflow and native valve dynamics.
A U-shaped filter frame captures valve-procedure debris while maintaining blood flow and improving catheter maneuverability.
Overlapping flaps and anchoring arms improve tricuspid valve sealing and migration resistance while enabling smaller catheter delivery.
A helical coil and movable clasp create a stable mitral THV anchor, improving sealing and reducing paravalvular leakage.
A valve-controlled single pressure tube replaces multiple heart pump lines, freeing surgical workspace while maintaining suction and inflation control.
A removable skirt around the sewing cuff improves annular sealing in calcified mitral or aortic valve implantation and helps limit paravalvular leaks.
Elastic sealing legs relax after deployment to fill annulus gaps, improving prosthetic valve anchoring and reducing paravalvular leakage.
A folded unibody double-wall stent separates sealing from valve support geometry to improve mitral anchoring and transcatheter delivery.
Tensioned strands through ventricular suture rings let a partially deployed prosthetic heart valve re-collapse for repositioning or removal.
