    摘要： 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.

    摘要： 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.

    摘要： 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.
