The application provides a valve clamping system. The valve clamping system includes a pushing device and a valve clip with coatings. The valve clip includes a push rod, the coatings, and a proximal clamping plate, and a distal clamping plate. The proximal clamping plate and the distal clamping plate extend radially outwardly relative to the push rod. The distal clamping plate is connected to the push rod. The proximal clamping plate is arranged between the push rod and the distal clamping plate. A valve holding space is formed between the proximal clamping plate and the distal clamping plate. The push rod is capable of driving the distal clamping plate to be expanded radially. The proximal clamping plate is capable of expanding toward the distal clamping plate by an elastic strain of the proximal clamping plate and is configured to clamp a valve tissue received in the valve holding space.

An adjustable suture locking apparatus includes a lock pin, an outer tube, a handle, and an adjusting device. The lock pin is used to receive or fix a suture. The outer tube defines a receiving cavity. The lock pin is disposed at a distal end of the receiving cavity. The handle includes a fixing portion coupled to a proximal end of the outer tube. The adjusting device is disposed on the fixing portion. The adjusting device is coupled to a proximal end of the suture and operable to adjust tensioning or loosening of the suture.

Adjustable suture locking apparatus

An adjustable heart valve repair system includes a suture implanting apparatus and a suture locker. The suture implanting apparatus is operable to implant a suture into at least one leaflet of a heart valve. The suture locker is operable to fix the suture. The suture locker includes an adjusting device to adjust tensioning or loosening of the suture.

An atrioventricular valve clamping device and an atrioventricular valve clamping system are provided in the disclosure. The atrioventricular valve clamping device includes a support member, an occluding member, and a clamping member. A direction of a central axis of the occluding member is regarded as a Z-direction, a direction parallel to a width direction of the clamping member and perpendicular to the Z-direction is regarded as a Y-direction, and a direction perpendicular to the Y-direction and the Z-direction is regarded as an X-direction. The support member has a length in the Z-direction. The occluding member is sleeved on the support member in the Z-direction. The clamping member is disposed outside the occluding member and configured to be unfolded or folded relative to the occluding member. The occluding member is resilient and has a three-dimensional shape.

The present disclosure provides a heart valve repair method, comprising: advancing a distal end of a suture implanting apparatus from an outside of a body through a transapical approach into a left ventricle or a right ventricle of a heart; holding each leaflet of a heart valve with the distal end of the suture implanting apparatus; implanting at least one suture into the leaflet; withdrawing the suture implanting apparatus from the body; advancing a distal end of a suture locking apparatus from the outside of a body through a transapical approach into the corresponding left ventricle or the corresponding right ventricle; using the suture locking apparatus to lock the plurality of sutures; and withdrawing the suture locking apparatus from the body. The heart valve repair method has a simple surgical procedure, a low degree of patient trauma, and a high success rate of surgery.
