Abstract: The present disclosure relates generally to apparatuses and methods for delivering an occlusion device to a paravalvular leak. In some embodiments, a paravalvular occlusion apparatus includes a catheter having main body including a proximal end and a distal end, a visualization element disposed in the distal end of the main body, and a working channel extending from the distal end of the main body. The catheter further includes an elongate shaft extendable from the working channel, wherein an occlusion device is coupled to the elongate shaft. In some embodiments, an occlusion device includes a leading end including a first section, and a trailing end opposite the leading end, the trailing end including a second section. The first section and the second section of the occlusion device are operable to be positioned along a perimeter of a prosthetic valve for blocking the paravalvular leak.

Abstract: Implantable devices formed of materials which are not readily imageable, and which may shift from a delivery configuration to a deployment configuration upon deployment, are delivered and deployed with a deployment/delivery device having sensors generating a signal indicating contact of the delivery/deployment device with tissue to guarantee purchase of the implantable device with tissue upon deployment. The implantable device may be a tissue anchor with talons which shift from a delivery configuration to a deployed configuration. The sensors may be positioned along a distal end of the delivery/deployment device to indicate purchase of the device with tissue, to ensure purchase of the talons with tissue upon deployment. The sensors may include at least three sensors, which may be spaced apart from one another, to indicate full contact of the distal end of the delivery/deployment device with tissue. The sensors may optionally be aligned with the talons.
