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

    It is a double lumen balloon catheter with radiopaque marker bands to allow for radiographic measurement.

    The Cocoon Sizing balloon is specifically designed for sizing atrial communications.

    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.

    • Delivery Sheath with hemostasis valve adapter - used to deliver the device.
    • Dilator – used to ease penetration of tissue
    • Loader – used to introduce the Cocoon Septal Occluder into the delivery sheath.
    • Delivery cable – The device is screwed onto the distal tip of the delivery cable, which allows for placement and retrieval of the device. The delivery cable is packed separately from the other accessories. The delivery cable can be used with Cocoon Duct and PFO occluders.
    • The Cocoon Septal Occluder Accessory set is available in 6F, 7F, 8F, 9F, 10F, 12F and 14F sizes.
    • The Cocoon Sizing balloon is available in two sizes - 24mm (CAB24) and 34mm (CAB34)
