Platinum nanocoating technology
Nitinol wire used in the Cocoon Duct Occluder is coated with Platinum atoms using nano fusion technology by plasma deposition
Raw nitinol
Electropolished
Platinum nanocoating
Platinum nanocoating makes the Cocoon Duct Occluder:
Biocompatible
Non-corrosive
Non-allergic
More radiopaque
Key highlights
- Hat-shaped design ensures secured implantation at the aorta and minimizes risk of migration into pulmonary artery
- Unique Platinum nanocoating
- Device is filled with polypropylene fabric to assist thrombogenicity
- Extended retention portion provides proper positioning of the device in the ductus arteriosus
- 100% occlusion rate at one-month follow-up1
- Ability to recapture and redeploy*
Design:
- Retention skirt diameter (Ø1)
- Device diameter at descending aorta (Ø2)
- Device diameter at pulmonary artery (Ø3)
- Device length (L)
*Recapture and redeployment is possible only if delivery cable is securely connected to the disc.
