Abstract: A leaflet resection device includes a first jaw, a second jaw pivotably connected to the first jaw, a first linkage assembly coupled to the first jaw, and a second linkage assembly coupled to the second jaw. The second linkage assembly includes a first resection blade and a second resection blade that are configured to cut a leaflet of a native heart valve or a previously implanted valve prosthesis along a curved path when the first and second linkage assemblies are actuated.

Abstract: A valve leaflet resection device includes a catheter (110), an electrode assembly (140) slidably disposed within the catheter and deployable from the catheter and configured to remove a portion of a leaflet of a heart valve, a leaflet retainer (130) slidably disposed within the catheter and deployable from the catheter, the leaflet retainer configured to grasp a leaflet of a heart valve, and a capture basket (120) configured to capture a resected portion of the leaflet of the heart valve upon retraction of the leaflet retainer.

Abstract: An assembly including a transcatheter valve prosthesis and a leaflet folding accessory configured for use when compressing the transcatheter valve prosthesis into the crimped configuration. The transcatheter valve prosthesis includes a frame and a prosthetic valve component including at least one leaflet disposed within and secured to the frame. The leaflet folding accessory includes a plurality of guide fingers. A leaflet contact portion of each guide finger is configured to be disposed radially within the frame and contact an inner surface of a leaflet of the at least one leaflet. During crimping of the transcatheter valve prosthesis, the plurality of guide fingers remain disposed radially within the frame such that the at least one leaflet preferentially folds around the plurality of guide fingers.
