Abstract: Devices and methods for removing a valve clip which is pre-positioned on a heart leaflet, the valve clip including a delivery catheter having a distal end portion configured to be positioned near a heart valve; a grasping tool deployable from the distal end portion of the delivery catheter, the grasping tool configured to grasp and manipulate a valve clip from an implanted condition to an elongated condition, wherein the valve clip in the elongated condition has an elongated width less than an implanted width of the valve clip in the implanted condition; and a removal tool extendable relative to the distal end portion of the delivery catheter, the removal tool configured to at least partially surround the valve clip in the elongated condition and to remove the valve clip from the heart valve leaflet.

Abstract: A transapical removal device that can be deployed in a catheter procedure to capture for removal or alteration a mitral valve clip or heart tissue, such as the anterior leaflet of the mitral valve, and methods of use are disclosed. The removal device includes a delivery catheter configured to be deployed near a mitral valve using a guide catheter. The delivery catheter has a snare head at the distal end, which assumes a collapsed state during movement of the delivery catheter through the guide catheter and deployed state for capturing a mitral valve clip or anterior leaflet. The snare head has one or more ablation delivery catheters configured to ablate tissue surrounding the pre-positioned mitral valve clip or anterior leaflet. In some arrangements within the scope of the present disclosure, the removal device includes a deployment mechanism for deploying a new transcatheter valve into the mitral valve.
