Abstract
Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium to attach a leaflet anchor having a leaflet suture to a mitral valve leaflet. A ventricular anchor has a hub with a helical anchor and a core wire extending through the helical anchor. A radiopaque marker may be axially movably carried on the core wire, and a spring biases the marker in a distal direction. The marker is advanced proximally on the tissue surface relative to the helical anchor as the helical anchor is advanced distally into tissue to secure a ventricular suture to the ventricular wall. A leaflet suture and the ventricular suture may be tensioned and connected by a suture lock to form an artificial chordae.
