Abstract

Devices, apparatus, and methods for catheter-based repair of cardiac valves, including transcatheter-mitral-valve-cerclage annuloplasty and transcatheter-mitral-valve reapposition. In particular, a target and capture device is provided for guiding a cerclage traversal catheter system through a cerclage trajectory, particularly through a reentry site of the cerclage trajectory. The target and capture device provides the user with a target through which the cerclage traversal catheter system must be guided, particularly under imaging guidance, so as to properly traverse the cerclage trajectory at any desired location, particularly at a reentry site. The target and capture device can, further, ensnare and externalize the cerclage traversal catheter system.
