Atrioseptostomy Balloon Catheter – Z-5™

The atrioseptostomy catheter is suitable for patients with a small left atrium as well as for newborn babies requiring an atrioseptostomy due to a congenital heart disorder.


Radiopaque Catheter Body & Balloon Image Marker  The NuMED Z-5™ Atrioseptostomy catheter body is Radiopaque to facilitate reliable positioning of the catheter. A Platinum image marker band is placed under the balloon for clear identification under fluoroscopy.

Micro-Thin Non-Compliant Balloon  The NuMED Z-5™ Atrioseptostomy balloon is micro-thin for low deflated profile that maintains tip flexibility. The Inflation of the balloon is controlled by volume. (see volumetric chart-Instructions for Use)

Reduced Balloon Size The reduced inflated balloon size should make Atrioseptostomy easier to perform on neonates with a small left atrium.

Tip Angulation  The tip of the catheter is angled at 35° to facilitate passage into the left atrium.

Inner Lumen  The NuMED Z-5™ Atrioseptostomy catheter has an inner lumen. The catheter end hole can
accommodate a guidewire.

  • Inner lumen with an opening at the catheter end for inserting a guide wire
