More Information
Summary:Leaflet extension devices for cardiac valve leaflets and methods of treating cardiac valve leaflets. Several embodiments are devices for resolving regurgitation in a cardiac valve comprising an expandable member and a cover. The expandable member has a stabilizing portion, a fixation member in opposition to the stabilizing portion, and a coaptation portion between the stabilizing portion and the expandable member. The stabilizing portion and the fixation member clamps the first native leaflet between the stabilizing portion and the fixation member. The coaptation portion projects from the stabilizing portion and the fixation member inwardly with respect to a first native leaflet of a cardiac valve such that the coaptation portion functionally extends the first native leaflet. The cover is attached to at least the coaptation portion of the expandable member.
