Publication number: 20230380969Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, the catheter can be anchored to a superior surface of a mitral valve leaflet and a leaflet anchor can be advanced into the mitral valve leaflet to secure the mitral valve leaflet to a leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.Type: ApplicationFiled: May 22, 2023Publication date: November 30, 2023Inventors: Gordon B.
