The Adona Interatrial Shunt

A novel interatrial shunt with integrated bi-atrial pressure monitoring that aims to enable shunting flow adjustments over time for more individualized management of heart failure.

Bi-Atrial Pressure Sensors
  • Direct LA and RA readings
  • Targeting 5+ automated readings / day

Adjustable Shunt Lumen

Designed to be:

  • Enlarged or reduced post-implant
  • 5-10 mm in target diameter
  • Temporarily opened to 14mm for left-heart access

ePTFE Encased Anchor
  • Biocompatible insulation encourages healthy tissue response

Shunt Lumen Adjustment Technology

Catheter

Shape Memory Nitinol

  • Shunt material chosen for malleable attributes at body temperature
  • Brief energy application returns shunt to nominal size

How It Works

  • Enlarge lumen to target size with balloon catheter
  • Reduce lumen size with Adona Induction Catheter

Adona Induction Catheter

  • Non-contact inductive energy transfer to implant
  • Designed to heat only targeted, insulated areas of shunt
  • Demonstrated negligible heating of tissue/blood in initial tests1

Illustrative Example

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).
