Ventricular Septal Defect Occluder
Modified rigidity and flexibility for different type of occluders - less stiffness of VSDO reduces the holding force to minimize the risk of third degree atrioventricular block.
Different waist lengths of VSD occluders minimize the negative impact of compress force to the patients.
Uniform and smooth oxide film on nitinol wire effectively prevents from the release of nickel ion to guarantee the great biocompatibility and long-term safety.
Hubless design helps with earlier endothelialization to minimize the risk of thrombosis.
