Bi-Flow in Animal Model

Bi-Flow Arterial Cannulae demonstrate significantly higher blood flow in the lower extremity compared to conventional cannulae at all CPB flow rates.

Dr. Chen’s paper1 demonstrates the superior femoral artery flow and pressure characteristics of Bi-Flow through a comparison with a standard femoral arterial cannula. It shows how Bi-Flow was simple to insert and position, and how the bidirectional cannula can supply adequate blood flow to the lower limb at full CPB support.


This is a well-designed and well-performed experimental study that clearly demonstrates the benefits of this bidirectional femoral cannula. This study suggests that Bi-Flow may have significant benefits in both minimally invasive valve replacement and other cardiac surgical patients undergoing peripheral cannulation.
