Abstract
A system configured to cut 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 hook catheter having a proximal end and a distal end, the hook catheter configured to extend from the distal end of the guide catheter through a first orifice of the cardiac valve. Further, the system may comprise a cutting mechanism extending from the hook catheter, the cutting mechanism configured to cut a portion of leaflet tissue of the cardiac valve. Finally, the system may include a handle coupled to the proximal end of the guide catheter, the handle comprising at least one control operatively connected to the cutting mechanism.
