1. A transcatheter valve laceration device comprising:
a leaflet support frame and a leaflet cutting assembly, both of which are movably mounted on a guiding structure and movable between contracted and expanded orientations, wherein said leaflet cutting assembly comprises a cutting element that comprises a sharp blade arm that has a pointed sharp tip at a distal end of said sharp blade arm; and
a blade actuator arm that has one end that pivots with respect to said guiding structure and an opposite end pivotally coupled to said sharp blade arm proximal to said pointed sharp tip; and
wherein in the expanded orientation, a blade protector of said leaflet support frame is positioned over said pointed sharp tip of a cutting element of said leaflet cutting assembly, and said pointed sharp tip is positioned to puncture a leaflet, and said cutting element is configured to cut the leaflet by axial movement of said leaflet cutting assembly.
