Claim 0:
1. A valve preparation device comprising:
a severing apparatus including a wire and a first arm that is biased to bow outwardly with respect to the wire; the first arm including a distal section, a proximal section, and a first electrode at an electrode section of the first arm, the electrode section positioned between the distal section and the proximal section;
a conically shaped tip connected to a distal end of the wire wherein the conically shaped tip includes a piercing electrode, and the valve preparation device is configured to energize the piercing electrode to form an opening through a heart valve leaflet; and
a sheath slidably movable from a delivery position in which the sheath covers the severing apparatus and a deployed position in which the sheath is proximally retracted to uncover the severing apparatus; wherein, in the deployed position, the first arm is configured to move from a first orientation to a second orientation, a portion of the distal section and a portion of the proximal section each extend a distance farther from the wire as compared to a distance the first electrode extends from the wire in the first orientation, and the portion of the distal section and the portion of the proximal section each extend a distance closer to the wire as compared to a distance the first electrode extends from the wire in the second orientation; and
the valve preparation device is configured to energize the first electrode to cut through a thickness of the heart valve leaflet while moving the first arm from the first orientation to the second orientation.
