The EasyFlow Aortic Cannula is intended for use in the perfusion of the aorta during cardiovascular surgery procedures requiring extracorporeal cardiopulmonary bypass for up to 6 hours. The EasyFlow Duo Cannula with guidewire is intended for use with cardiopulmonary bypass as an arterial return femoral cannula for up to 6 hours.

Easyflow & Easyflow Duo are single-use, non-toxic, non-pyrogenic fluid path devices and supplied sterile and individually packaged. The Easyflow & Easyflow Duo are composed of the cannula and a malleable obturator inserted into the cannula to allow the placement of the cannula along the Artery. The cannula is an open lumen PVC polymer tube incorporating wire reinforcement in distal sections. The distal sections of the cannula are perforated with multiple holes at multiple stages to allow fluid flow. The clear proximal section is not reinforced to allow clamping; the proximal end terminates in a 3/8" barbed connector for standard cardiopulmonary bypass tubing In the Easyflow Duo models the device has a 0.035" hole punched in the very distal tip of the cannula and the obturator has an approx. 0.035" internal diameter central lumen to accommodate a 0.035" guide wire used to drive the cannula along the vessel till its final placement. Once the cannula is positioned onto the vessel the surgeon removes the obturator from the cannula tubing and connects it to the arterial line. The Easyflow is packaged as sterile stand-alone device while the Easyflow Duo is packaged into a tray containing also a Guidewire, a Needle and Vascular Dilators in order to have a kit for vascular access packaged together with the cannula. The Easyflow & Easyflow Duo are the modified version of the disposables currently marketed as the Easyflow cannula (K060101) and the Easyflow Duo cannula (K091542). Both modified and unmodified cannulae models are recommended for use as an arterial return cannula during cardiopulmonary bypass up to six hours
