Claim 0:
1. A transapical removal device comprising:
a delivery catheter configured to be deployed near a mitral valve using a guide catheter;
a snare head at a distal end of the delivery catheter, the snare head having (i) a collapsed state for movement of the delivery catheter through the guide catheter and (ii) a deployed state for capturing a mitral valve clip that has been pre-positioned on a mitral valve leaflet; and
a snare head controller connected at a proximal end of the delivery catheter and configured to control transition of the snare head between the collapsed state and the deployed state;
wherein the snare head includes
a removal tool comprising a snare basket and one or more ablation delivery catheters secured to the snare basket, the snare basket configured to at least partially surround the pre-positioned mitral valve clip, and the one or more ablation delivery catheters configured to ablate the mitral valve leaflet for removal of the pre-positioned mitral valve clip from the mitral valve leaflet, and
a grasping tool having opposed first and second members moveable away from and toward each other between an open state and closed state, respectively, and configured to grasp and manipulate the pre-positioned mitral valve clip while the snare basket at least partially surrounds the pre-positioned mitral valve clip; and
wherein the snare head controller is configured to (x) control the position and/or size of the snare basket during the deployed state, (y) move the grasping tool between the closed state and the open state, and/or (z) control ablation delivery to the mitral valve leaflet through the one or more ablation delivery catheters, wherein the snare basket defines an interior space, and the grasping tool is positionable at least partially within the interior space of the basket, and
wherein magnets are provided on the snare basket to facilitate closing the snare basket around the mitral valve clip.
