BLOCKING DEVICE AND BLOCKING SYSTEM

The present invention relates to a blocking device and a blocking system for blocking a ventricular septal rupture. The blocking device comprises a blocking frame and a membrane. The membrane covers at least part of the surface of the blocking frame. The blocking frame comprises two blocking disks arranged oppositely and a narrow middle portion connecting the two blocking disks. The narrow middle portion is used for being located in the ventricular septal rupture. The two blocking disks are configured for, in an expanded state, clamping the myocardium around the ventricular septal rupture at both axial ends. The two blocking disks each comprise a plurality of independently arranged legs, and all the legs in each of the blocking disks are arranged circumferentially around the longitudinal axis of the blocking frame. The present invention can effectively reduce the damage to the myocardial tissue, and features higher safety and more stable and reliable clamping. La présente invention concerne un dispositif de b
