Cocoon PFO Occluder

The Cocoon PFO Occluder is a percutaneous, transcatheter closure device intended for the occlusion of all types of PFO's in patients with a history of stroke diagnosed by echo-cardiography with right-to-left shunting during Valsalva maneuver.


The Cocoon PFO Occluder is a self expandable double disk device manufactured from braided Nitinol wires coated with platinum. The two discs are linked together by a short connecting waist allowing free motion of each disc. 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.
