Devices, systems, and methods for supplementing, repairing, or replacing a native heart valve leaflet
First Claim
1. An implant that supplements, repairs, or replaces a native heart valve leaflet or leaflets 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, a neoleaflet element coupled to the scaffold within pseudo-annulus and being sized and shaped to occupy the space of at least a portion of one native heart valve leaflet to provide a one-way valve function that, in response to a first pressure condition, assumes a valve opened condition within the pseudo-annulus and, in response to a second pressure condition, assumes a valve closed condition within the pseudo-annulus, and spaced-apart struts appended to the scaffold and being sized and configured to contact tissue near or within the heart valve annulus to brace the scaffold against migration within the annulus during the one-way valve function.

Abstract
Devices, systems and methods supplement, repair, or replace a native heart valve. The devices, systems, and methods employ an implant that, in use, extends adjacent a valve annulus. The implant includes a mobile neoleaflet element that occupies the space of at least a portion of one native valve leaflet. The implant mimics the one-way valve function of a native leaflet, to resist or prevent retrograde flow. The implant restores normal coaptation of the leaflets to resist retrograde flow, thereby resisting eversion and/or prolapse, which, in turn, reduces regurgitation.
