Nit-Occlud® PDA

The Nit-Occlud® PDA occlusion system is designed for the safe and atraumatic occlusion of the congenital heart defect PDA (persistent ductus arteriosus). Three different types and a broad variety of sizes make the unique spiral-shaped occlusion device the ideal choice for the closure of almost PDA types and sizes.


Coil Occluder  The nitinol coil was specifically designed for PDA closure procedures. The degree of stiffness decreases from the aortal side to the pulmonary side, allowing the coil to adapt perfectly to the anatomy of the PDA.

Safe closure  The unique spiral shape enables the coil to be applied accurately and without trauma while simultaneously ensuring a closure of all PDA types and sizes up to 6 mm in diameter.

Easy to use  The specially developed application system is easy to use. It is inserted by means of a 4–5 F implantation catheter. The occluder can be repositioned as necessary until the coil is released.


  • Repositioning possible at any time prior to release
  • Pre-mounted system: the Nit-Occlud® coil is mounted at the distal end of the introducer system using a patented releasing mechanism
  • Introducer system is pre-mounted on the disposable handle
  • Disposable handle for a safe and simple release
  • Radiopaque implantation catheter with gold marker
  • MR compatible
  • Single-use system
  • 4 F or 5 F system


Nit-Occlud® PDA is commercially available outside the USA.
