ASD Occluder I(Double-rivet)
Double-rivet self-expandable design is employed for secure and firm clamping.
Nitinol material offers excellent biocompatibility and shape memory.
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.
ASD Occluder II (Single-rivet)
Single-rivet self-expandable design helps reduce metal implants and load to the heart.
Nitinol material offers excellent biocompatibility and shape memory for secure and firm clamping.
Physical kneading technology is used for bundling to ensure firm press fitting without solder joints.
PET flow-occluding fabric is designed for immediate blocking of blood flow.
ASD Occluder 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 gaps among the disc wires preserve a pathway for future transseptal treatments.
With plasma treatment process, a dense and uniform oxide coating is formed on the surface of wire to minimize the precipitation of nickel ions.
ASD Occluder IV (Biodegradable)
(Product candidate)
Biodegradable material that minimizes compression and wear on surrounding tissues caused by metal implants, which lowers the risk of long-term complications, and that leaves available for additional future treatment options.
Patented mold locking structure to ensure secure and firm clamping.
Platinum marker bands outside the biodegradable wire to enable precise positioning during the procedure.
