Cocoon Septal Occluder

The Cocoon Septal Occluder is used in the transcatheter closure of atrial septal defects.


It is a self expandable double disk device manufactured from braided nitinol wire braid and coated with platinum.​

The discs are connected by a waist at the center of the discs. Platinum provides superior biocompatible properties compared to Nitinol. The platinum coating also provides radio opacity which enables easy positioning in the defect. The discs are filled with polypropylene fabric which aids in total occlusion of defect.​
