Bi-Flow® ECMO – The unique bidirectional cannula is now validated up to 29 days

After a successful first year of experience in the cardiac surgery setting, Bi-Flow is now validated for up to 29 days of use. This unique bidirectional cannula is designed to reduce the risk of limb ischemia in an easy, safe and reproducible way for patients receiving ECMO.

Unlike traditional cannulae, Bi-Flow’s patented design incorporates a unique elbow and downstream perfusion channel. The cannula is easy to insert and remove and provides simultaneous systemic and distal perfusion to the lower limb.
Limb ischemia is a potentially life-threatening complication of femoral artery cannulation. It can affect between 10% and 70% of patients undergoing VA-ECMO and may have devastating consequences such as higher mortality, higher morbidity and longer hospital stay.[1]
The LivaNova Bi-Flow cannula is designed to reduce this risk[2] in all procedures requiring femoral cannulation. In addition to its unique bidirectional perfusion design, Bi-Flow also offers:

  • Simple and straightforward insertion and removal process, both percutaneously using a standard needle and guide wire technique or after a surgical cut-down
  • DOP-free tubing and Ph.I.S.I.O. coating for enhanced biocompatibility
  • Optimal pressure drop level for adequate systemic perfusion
  • Unique fixation device designed to ensure that it remains correctly positioned during the procedure

In addition to the ECMO version, Bi-Flow is approved also for cardiopulmonary bypass procedures for periods up to 6-hours, to deliver its benefits to patients undergoing complex cardiac surgery procedures and requiring femoral cannulation.
