Embodiment
[0053] This embodiment provides a transcatheter heart valve clipping system, and takes the treatment of mitral valve regurgitation as an example to describe in detail. Use this as a basis.
[0054] See Figure 14 As shown, first place the heart valve clip 1 at the position of the left ventricle through the delivery system, then push the heart valve clip 1 to the top of the valve, expand the lower clamping arm 20 to a certain angle through the head-hanging sheath tube seat 4, and then move upward Push the heart valve clamp 1 so that the clamping arm 20 wraps around the valve leaflet from the ventricular surface, and then release the puller wire 50 through the tail end 2 of the puller wire, so that the upper clamping arm is unfolded and the valve leaflet is firmly pressed against the lower clamping arm 20 Above, after determining that the valve leaflet clamping position is appropriate and the reflux treatment effect is achieved, the lower clamping arm 20 is closed through the h...
