PDA Occluder I (Double-rivet )
Double rivet self-expansion design, can be firmly clamped.
Nitinol material offers excellent biocompatibility and shape memory.
The cylinder or cone shape ensures a close and stable fit to the wall of ductus arteriosus.
Physical kneading technology is used for bundling to ensure firm press fitting without solder.
PET flow-occluding fabric is designed for immediate blocking of blood flow.
PDA Occluder II (Single-rivet)
Single-rivet self-expandable design can reduce metal implants and load to the heart.
Nitinol material offers excellent biocompatibility and shape memory.
The cylinder or cone shape ensures a close and stable fit to the wall of ductus arteriosus.
Physical kneading technology is used for bundling to ensure firm press fitting without solder.
PET flow-occluding fabric is designed for immediate blocking of blood flow.
PDA Occulder III
(Oxide Coating)
Single-rivet design: The original riveting head is replaced by the datura-shaped braided mesh for allowing more flattened discs to facilitate endothelialization.
The cylinder or cone shape ensures a close and stable fit to the wall of ductus arteriosus.
With plasma treatment process, a dense and uniform oxide coating is formed on the surface of wire to minimize the precipitation of nickel ions.
