Introducing

The Adona Interatrial Shunt

A chronically-adjustable interatrial shunt with integrated bi-atrial pressure monitoring that is designed to provide individualized shunt therapy for the management of heart failure.

  • Direct LA and RA readings
  • 5+ automated readings / day
  • Size can be enlarged or reduced post-implant
  • 5-10 mm target diameter
  • Can be temporarily opened to 14mm for left-heart access
  • Biocompatible insulation encourages healthy tissue response

Bi-Atrial Pressure Sensors

  • Direct LA and RA readings
  • 5+ automated readings / day

Adjustable Shunt Lumen

  • Size can be enlarged or reduced post-implant
  • 5-10 mm target diameter
  • Can be temporarily opened to 14mm for left-heart access

ePTFE Encased Anchor

  • Biocompatible insulation encourages healthy tissue response

Shunt Lumen Adjustment

Adjustable Shunt Lumen


  • Comprised of shape memory nitinol
  • Enlarge to target size with balloon catheter
  • Returns to nominal size with brief energy application

Adona Magnetic Catheter


  • Non-contact inductive energy transfer to implant
  • Heats implant internally in targeted, insulated areas
  • Initial testing: negligible tissue/blood heating during adjustment

Illustrative Example

Real-time pressures measured directly by the Adona system confirm that enlarging shunt size reduces left atrial pressure (LAP) by unloading a small volume of blood into the right atrium (RA).
