Original Abstract Submitted
Leaflet perforation tools and associated methods. A leaflet perforation tool can comprise a catheter, a lacerating member configured to pierce a leaflet to form a pilot puncture, and an expansion member configured to expand the pilot puncture into a leaflet opening. In another example, a leaflet perforation tool can comprise a catheter and a nosecone that comprises at least one blade. The nosecone can form a leaflet opening in a leaflet, and blade can form a leaflet slit that is connected to the leaflet opening. A method can comprise forming a leaflet opening within a leaflet with a leaflet perforation tool, positioning a replacement prosthetic valve within the leaflet opening, and radially expanding the replacement prosthetic valve. A method also can comprise forming a pilot puncture within a leaflet and expanding the pilot puncture into a leaflet opening.
