CAPIOX® FX Advance



Advanced to the Next Level​

The Capiox® FX Advance Oxygenator with Integrated Arterial Filter advances your oxygenator to the next level by enhancing flow dynamics1 resulting in lower reservoir minimum operating levels and increased maximum blood flow rates. Now, you can expand your options and choose a smaller, lower prime oxygenator for even more patients.


  • The design of the Capiox® FX Advance Oxygenator contributes to fewer blood transfusions2
  • Improved flow dynamics reduces blood turbulence and enhance gaseous microemboli removal3
  • Rotating, curved venous inlet enhances ease-of-use
  • Increased maximum blood flow to 5 L/min on the CAPIOX® FX15 Advance Oxygenator, with 3.000 mL reservoir, for use on a wider range of patients*
  • Decreased minimum operating level of 150 mL on the CAPIOX® FX15 and FX25 Advance Oxygenators, with the 4.000 mL reservoir, reduces hemodilution3

* Use of Vacuum Assisted Venous Drainage may be required to achieve flow rate of 5 L/min.
