Features of Abbott’s Industry-Leading Amplatzer PDA Line1
While offering various options for patent ductus arteriosus (PDA) occluder therapy, the Amplatzer devices share certain characteristics:
- Provide secure positioning in the ductus
- Achieve complete closure
- Promote tissue in-growth
- Provide flexibility and conformability
AMPLATZER DUCT OCCLUDER: FOR LARGE PDA CLOSURE
Backed by a 20-year track record of performance,1 the Amplatzer Duct Occluder can accommodate large PDAs with a single device—which can aid in minimizing the complexity of the procedure.
Features include:
- Data showing more than 98% complete occlusion at 6 and 12 months2
- A cone shape that can help conform to tapering ducts
- A retention skirt to prevent embolization
Its treatment range:
- Ductus diameter: 3.0-12.0 mm
- Ductus length: > 3.0 mm*
*The Amplatzer Duct Occluder can be used in any length defect as long as the device does not extend more than 3 mm into the pulmonary artery or does not occupy over half of the pulmonary artery lumen.

AMPLATZER DUCT OCCLUDER II: Versatility to Conform to a Variety of PDAs
The Amplatzer Duct Occluder II is engineered using 2 articulating discs and multi-layered mesh that conforms to most classifications of PDAs.
Features include:
- Symmetrical design so it can be introduced via pulmonary or aortic approach3
- 6 planes of occlusion for full, cross-sectional coverage4
- Fabric-free design allows for delivery through a low-profile catheter—while still achieving a very high occlusion rate3
Its treatment range:
- Ductus diameter: 2.5-5.5 mm
- Ductus length: > 5.0-12.0 mm

Amplatzer Duct Occluder II AS: For Small PDA Closure
The Amplatzer Duct Occluder II AS (additional sizes) is able to occlude a variety of duct sizes, or elongated ducts, while minimizing protrusion into the aorta and pulmonary artery.
Features include:
- Low-profile retention discs and end screw—specifically for small anatomy
- Symmetrical design for either pulmonary or aortic approach
- Tightly woven mesh to minimize residual shunt immediately after positioning
- Flexible delivery wire for ease of deployment
Its treatment range:
- Ductus Diameter: ≤ 4.0 mm (measured by angiography)
- Ductus Length: 3-8 mm (measured by angiography)

AMPLATZER PICCOLO: FOR PDA CLOSURE
The Amplatzer Piccolo Occluder is able to occlude a variety of duct sizes, while minimizing protrusion into the aorta and pulmonary artery.
Features include:
- Low-profile retention discs and end screw—specifically for small anatomy
- Symmetrical design for either pulmonary or aortic approach
- Tightly woven mesh to minimize residual shunt immediately after positioning
- Flexible delivery wire for ease of deployment
