Venous Valves TRIZ Cases
- Expandable Venous Valve Structure for Flexible Leaflet Sealing
Flexible leaflets held away from the vessel wall improve sealing across varying vessel diameters while reducing stress and preserving retrograde flow control.
- Independent Gripper Fixation for Minimally Invasive Mitral Repair
A catheter-delivered independent gripper coapts mitral valve leaflets with repositionable fixation to reduce regurgitation and tissue trauma.
- Independent Gripper Catheter for Repositionable Mitral Valve Repair
Movable grippers and fixation elements enable precise leaflet coaptation, repositioning, and removal in minimally invasive mitral valve repair.
- Partial-Sinus Valve Prosthesis for Blood Stagnation Control
An asymmetric partial sinus creates vortex blood flushing around the valve leaflet to limit stagnation, thrombosis, and loss of valve function.
