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

Manufacture:

Type:

Double Disc 

self centering (LA disc more than 4 mm than a RA disc)

Material:

Nitinol – 55 % Nickel, 45% Titanium

Design:

Nitinol wires woven to form 2 discs separated by a  waist

Coating:

The device is coated with Platinum to insulate Nickel from the system to avoid Nickel leaching into the Blood…

Poly propylene fabric inserted inside the mesh to assist arrest shunt from LA to RA.

Design:

It is designed in the shape of Hat with a tapering section and extended diameter at 1 side to hold device at the aortic end from slipping into the pulmonary artery.

Coating:

Platinum

The PFO Device consists of 2 Discs, made up of Platinum coated Nitinol Wires, connected by a Thin waist. The RA Disc is larger than the LA Disc as the Shunt has to close from RA to LA. The Waist is thin ie., of small Diameter when compared with ASD and VSD Device. The length if the waist is longer than ASD/VSD Devices to accommodate the width of the Tunnel.

Cocoon VSD Devices have been designed to have a SOFT WAIST, wherein the WAIST, squeezes out to RV and LV Side instead of putting pressure on the Septum and Bundle of HIS

The Waist offers minimum pressure on the Septum avoiding pressure on the Muscle Fibers, which conduct Electrical pulses to the LV and RV thus avoiding Heart Block.

Manufacture:

Type:

Self Expanding Double Disc Device

Material:

The Device is made of Platinum coated Nitinol wire mesh.

Design:

Discs are connected together by a short connecting waist.

Coating:

The platinum coated disc and the waist is filled with multiple Polypropelene woven fabric sewed to the body of the device, which aids as total occlusion of the defect.
