    摘要： A stent delivery system includes an inner tubular member, a stent disposed over a distal section of the inner tubular member, a locking member positioned over the inner tubular member proximal of the stent, and an outer tubular member covering the stent and the locking member in a delivery configuration. A portion of the stent can be positioned in the locking member in the delivery configuration. The locking member can include a tubular proximal section, and a plurality of fingers extending distally from the tubular proximal section. The plurality of fingers can include a first finger and a second finger. The plurality of fingers can have a locked configuration with each of the first finger and the second finger parallel to a longitudinal axis, and an unlocked configuration with one of the first finger and/or the second finger forming an angle with respect to the longitudinal axis.

    摘要： A surgical prosthetic heart valve has a supporting structure and a plurality of leaflets, the supporting structure generally having an annular shape with a blood flow channel defined in the annular shape and having opposite inflow and outflow sides along an axial direction of the annular shape, the plurality of leaflets connected to the supporting structure to control the blood flow channel to open or close. The supporting structure includes a first annular band and a second annular band, both of which are provided with deformable sections spaced from each other in the circumferential direction for allowing diameter expansion of the respective annular bands. The surgical heart valve achieves the diameter expansion of the annular bands through the deformable sections, thereby addressing the problem of postoperative variation in a valve-in-valve operations.

    摘要： Coaptation-assist devices (20) are provided for treating a native atrioventricular valve. The coaptation-assist devices (20) include a ventricular anchor (30), which includes one or more wires (35), and which is configured to be positioned in a ventricle; and a neo-leaflet (32), which is supported by the ventricular anchor (30) and is configured to at least partially replace function of a target native leaflet of the native atrioventricular valve by providing a surface of coaptation (34) for one or more opposing native leaflets. In some configurations, the ventricular anchor (30) includes a proximal subannular anchor (54), which includes a digitate anchor (56) that is shaped so as to define a plurality of fingers (60) having a plurality of curved superior peaks (66) that point in a superior direction and engage a subannular surface of the target native leaflet. Other embodiments are also described.
