Implanting the implant includes implanting the implant such that the tension element undergoes the conformational changes responsively to the cardiac cycle of the patient in a manner in which the tension element cyclically increases and decreases pressure applied to at least one leaflet of the heart valve by the elongate element.

DEVICE FOR SECURING HEART VALVE LEAFLETS

A heart valve prosthesis is provided that includes a first member and a second member. The first member comprises a first central portion to be disposed adjacent to a line of coaptation on a first side of two adjacent heart leaflets and peripheral portions to be placed into direct contact with the two adjacent heart leaflets. The second member is separate from or can be separable from the first member, for example during delivery. The second member has a central portion and peripheral portions configured to be placed into direct contact with a second side of the two adjacent heart leaflets.

Clamping instrument and clamping assembly

The invention provides a clamping instrument and a clamping assembly, which mainly comprises a positioning base, a moving base, at least two clamping arms connected with the moving base, at least two linkage arms respectively connected with each of the clamping arms and the positioning base, and an actuating rod respectively penetrating through the positioning base and the moving base, wherein the positioning base is rotated circumferentially and fixed axially relative to the actuating rod, and the moving base is rotated circumferentially and moves axially relative to the actuating rod; when the movable rod is rotated circumferentially, a distance between the moving base and the positioning base can be changed, and then each of the clamping arms is linked to be rotated around the moving base to be in an unfolded position or a clamped position so as to clamp a preset site of a human tissue. Thus, the rotating amplitude of the clamping arms can be finely adjusted to provide a clamping force with high precision in the present invention.

ANCHOR DESIGNS CONFIGURED FOR ANCHOR MIGRATION/BACKOUT CONTROL

An anchor configured to maximize the surface area of the anchor to improve anchor retention is disclosed. The anchor may be configured with a width that differs from a thickness of the anchor. In some embodiments, the anchor be configured as a helical ribbon defining a central lumen about a central axis extending through the helical ribbon. The helical ribbon may vary in width, thickness, central lumen diameter, or a combination thereof, along its extent. The anchor may include retention features that are configured to promote tissue and/or implant interaction for improved anchor retention.

Aspects of the disclosure include systems including a delivery device having a handle assembly, a shaft assembly having a distal portion, and a helical elongated member positioned at least partially over the shaft assembly and interconnected to the handle assembly. The system also includes a prosthesis positioned over the distal portion. The prosthesis has a stent frame having an inner surface and an outer surface, a valve structure positioned within the stent frame, and a track formed by one or more guides positioned on and extending from one of the inner or outer surfaces of the stent frame. The helical elongated member is configured to be moved in and out of the track to selectively compress or allow the prosthesis to expand. Methods of loading and delivering the prosthesis using systems of the disclosure are also disclosed.

RVOT WIRE CAPTURING (RWC) SYSTEM IN MITRAL VALVE CERCLAGE ANNULOPLASTY
20220354649 · 2022-11-10 · ·

A mitral cerclage annuloplasty apparatus comprising of a catheter with a blocking member and a capturing member. The blocking member is in the shape of a pigtail or a balloon, and is configured on the distal portion of the catheter preventing the catheter from traversing through an unsafe zone thereby enabling the catheter to pass through the safe zone. This prevents damage to critical cardiac tissues. The capturing member is adapted for pulling out a RVOT cerclage wire into the IVC, and comprises of an expandable and collapsible mesh so that the RVOT cerclage wire is captured and directed into the WC through the safe zone. Thus the RVOT cerclage wire is passed through the RV without damaging the heart tissue forming a complete circle around the mitral valvular annulus.
