View our press release which includes a quote from Dr. Alexander Assmann describing the remarkable decrease in wall shear stress profiles and turbulence that our dispersive cannula tip affords to surgeons.
For conventional cardiac surgery, we have a comprehensive portfolio of solutions in a wide range of tips and sizes to meet all your procedural needs.
Whether your needs are for adult, pediatric or any age in between, we’ve got you covered. Please visit our product highlights section where you can learn more about our conventional cannulae offering including our recently FDA-approved Optiflow cannulae family. OptiFlow venous cannula delivers high drainage capability with a 13 cm holed area. Venous cannula is available in single, dual or triple stage, and the dual stage is available with low profile tubing for less intrusion into the operative field. Or our aortic arch cannula that offers several tip designs and configurations for maximum clinical flexibility. And our cardioplegia and vent offering gives you a choice of sizes and designs for all access points.
In our multimedia section, we added one animation that demonstrates the features of Optiflow Arterial Cannula. As you may be aware, plaque dislodgements from the aortic wall may induce neurological complications in adult patients undergoing extracorporeal circulation (ECC) in cardiac surgery. Embolization of these plaques is correlated with high wall shear stress from the placement of aortic cannulae in the aortic arch. Optiflow helps to reduce shear stress on the aortic wall, thanks to its unique, 3-dimensional dispersion basket tip designed to reduce the pressure gradient along the cannulae, allowing for more natural physiciological flow that reduces wall shear stress by up to 50%.1
