Cocoon Duct Occluder

The Cocoon Duct Occluder is used in the transcatheter closure of patent ductus arteriosus. It is a self expandable umbrella shaped device manufactured from braided nitinol wires and coated with platinum. 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.
