Cocoon Ventricular Septal Occluder

The Cocoon VSD Occluder is a percutaneous, transcatheter ventricular septal defect (VSD) closure device intended for the occlusion of hemodynamically significant ventricular septal defects.


The Cocoon VSD Occluder is a self expandable double disk device manufactured from braided Nitinol wires coated with platinum. The two discs are linked together by a connecting waist and the waist diameter is corresponding to the defect size. 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.
