Amplatzer Duct Occluders

AMPLATZER Patent Ductus Arteriosus

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


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)
