LivaNova Announces U.S. Launch of Optiflow Arterial Cannulae Family
Novel dispersive tip design reduces aortic wall shear stress by 50 percent, improves hydrodynamics, potentially decreases cardiac surgery risk
Unlike standard arterial cannulae, Optiflow Arterial cannulae feature a unique basket tip with large openings that allow a more physiologically compatible dispersive design. This design has been shown to significantly reduce WSS and turbulence,1 thereby improving hydrodynamics and potentially reducing ischemic complications from extracorporeal circulation (ECC) during cardiac surgery.
“The sandblasting effect of conventional arterial ECC cannulae can result in endothelial damage and plaque mobilization, and arterial embolization of atherosclerotic plaques during ECC surgery frequently results in severe complications such as stroke or ischemia of other organs,” said Dr.
In a recent trial using advanced numerical evaluation of a human aorta model and its branches simulating the effect of aortic cannulae on blood flow characteristics, Assmann et al. demonstrated a 50 percent decrease in average and peak WSS during both pulsatile and nonpulsatile ECC with dispersive cannula tips compared to standard cannula tips1.
“Built on a foundation of demonstrated hydrodynamic performance improvement,
Designed to reduce patient complications and meet cardiac surgery procedural needs, the Optiflow Arterial Cannulae Family is another example of LivaNova’s efforts to transform medical innovation into meaningful solutions.
