Optimal sealing of defects
Designed to minimize nickel leaching
Platinum nanocoating
Softness to protect
Conformability
disc level
Flexibility at the disc level
Cocoon Septal Occluder requires 40.3% less force compared to competitor for displacement at 15 mm indicating higher flexibility of the discs
Displacement at 15 mm
Softness to Protect
Cocoon Septal Occluder requires 30.4% less force compared to competitor for displacement at 8 mm indicating higher softness of the discs
Displacement at 8 mm
Conformability at the discs
Right disc
Cocoon Septal Occluder:
Better conformability of the right atrial disc
Competitor:
Good conformability of the right atrial disc
Cocoon Septal Occluder is highly conformable
Left disc
Cocoon Septal Occluder:
eft atrial disc shows no gap with Cocoon
Septal Occluder
Competitor:
Gap is evident, chances of edge penetration are higher with the Competitor
Cocoon Septal Occluder is highly conformable
Designed to minimize nickel leaching Platinum nanocoating
- Ultrathin layer of Platinum atoms using nanofusion technology is coated on the Nitinol wire by a process called plasma deposition
- Platinum nanocoating makes the Cocoon Occluders inert, biocompatible, non-corrosive and non-allergic and also enhances radiopacity
Raw nitinol
Electropolished
Platinum nanocoating
Platinum nanocoating makes the Cocoon Septal Occluder
Optimal Sealing of Defects
The waist of Cocoon Septal Occluder has adequate sealing strength at the level of the discs: Up to 100% immediate closure rates1, 2
