    Abstract: Disclosed herein are exemplary embodiments of suture securement devices that replace the need to tie knots in sutures. Some embodiments comprise an annular outer body and one or more suture engagement tabs extending inwardly from the outer body. The devices can comprise a superelastic and/or shape-memory material and have a generally in-plane initial configuration. The suture engagement portions are deformable out-of-plane to an active configuration with the outer body compressed and the tabs interlocked with each other. The device can be heat-set in the deformed configuration. The interlocked tabs exert a pinching force on sutures passing between them that restricts the sutures from sliding through the opening in one longitudinal direction.

    Abstract: In one embodiment, a leaflet capture device for improving the coaptation of heart valve leaflets is provided. The leaflet capture device can include a first clip portion having inner and outer portions. The inner and outer portions can be configured to compress tissue of a first heart valve leaflet therebetween to secure the first clip portion to the first leaflet. The leaflet capture device can further include a second clip portion having inner and outer portions. The inner and outer portions can be configured to compress tissue of a second heart valve leaflet therebetween to secure the second clip portion to the second leaflet. The first and second clip portions can be separately deployable onto the first and second leaflets and secured to one another in vivo to bring portions of the first and second leaflets into closer proximity to each other, thereby improving coaptation of the first and second leaflets.

    Abstract: Some disclosed suture securement devices comprise a flat, thin, generally planar body that has one or more suture engagement slots extending into the body from a perimeter inlet for receiving sutures laterally into the device. The slots can be resiliently widened to receive a suture and then released to clamp onto the suture. Some embodiments include two or more such suture engagement slots that independently receive and secure different sutures. Some embodiments include one or more locking tabs that have a closed position that retains the slots against widening and blocks the inlet to the slot. In some embodiment two or more slots are position next to each other on the same side of the device, while in other embodiments slots are positioned on opposite sides of the device. Other types of suture securement devices are also disclosed.

    Abstract translation: 一些公开的缝合线固定装置包括平坦的，薄的，大致平坦的主体，其具有一个或多个缝合线接合槽，其从周边入口延伸到主体中，用于将缝合线横向接纳到装置中。 狭槽可以弹性加宽以接收缝合线，然后释放以夹紧到缝合线上。 一些实施例包括两个或更多个这样的缝合接合槽，其独立地接收和固定不同的缝合线。 一些实施例包括具有闭合位置的一个或多个锁定突出部，该关闭位置保持狭槽以防止加宽并阻塞入口到狭槽。 在一些实施例中，两个或更多个槽位于装置的相同侧上彼此相邻的位置，而在其它实施例中，缝隙位于装置的相对侧上。 还公开了其他类型的缝线固定装置。

    Abstract: A low pressure gradient prosthetic heart valve for implant in a human. The valve includes a support frame with undulating inflow cusps and outflow commissure posts to which flexible leaflets attach and coapt in a flow area. The commissure posts angle outward in a neutral state to widen the outflow orifice area. Also, the leaflets are designed to fit within the support frame and expand outward in a valve open state without creating a shelf or belly that would restrict flow.
