Estimating the term…
Devices, systems and methods retain a native heart valve leaflet to prevent retrograde flow. The devices, systems, and methods employ an implant that, in use, rests adjacent a valve annulus and includes a retaining structure that is sized and shaped to overlay at least a portion of one or more native valve leaflets. The retaining structure retains the leaflet or leaflets it overlays, to resist leaflet eversion and/or prolapse. In this way, the implant prevents or reduces regurgitation. The implant does not interfere significantly with the opening of and blood flow through the leaflets during periods of antegrade flow.
An implant that retains a native heart valve leaflet to resist retrograde flow comprising a scaffold sized and configured to rest adjacent all or a portion of a native heart valve annulus, at least a portion of the scaffold defining a pseudo-annulus and including a retaining structure near or within the pseudo-annulus that is sized and shaped to overlay at least a portion of one or more native valve leaflets, the scaffold further including spaced-apart struts sized and configured to contact tissue near or within the heart valve annulus to brace the retaining structure to resist leaflet eversion and/or prolapse.
