Abstract

A prosthetic device to occlude an opening present in a defective atrial septum, the device having at least two clips for firmly gripping peripheral portions around the opening. The material further has a flat occluder to close the opening, and at least two fastening means for securing the clips to the flat occluder. The prosthetic device can be applied to the defective atrial septum permanently and easily in an percutaneous-transvascular manner.

Claims

1. A prosthetic device to occlude an opening present in a defective atrial septum, the device comprising:

at least two clips for firmly gripping peripheral portions around the opening;
