Abstract
A system for cutting leaflet tissue at a cardiac valve may comprise a guide catheter having a proximal end and a distal end, wherein the distal end of the guide catheter is steerable to a position above a cardiac valve. The system may also include a handle coupled to the proximal end of the guide catheter, the handle comprising at least one control configured to steer the guide catheter to the position above the cardiac valve. Finally, the system may comprise a cutting mechanism routable through the guide catheter and able to be positioned at the distal end of the guide catheter, the cutting mechanism configured to cut a portion of leaflet tissue of the cardiac valve.
