FLO-THRU Intraluminal Shunt, is a sterile, single use, disposable one-piece radiopaque silicone tube with atraumatic bulbs shaped at each end. Openings at the ends of the bulbs allow blood to flow through the shunt and distal to the anatomosis. A radiopaque tab, which identifies the outer diameter of the bulbs, is attached to the shunt by a tether to faciliate positioning and removal of the shunt. FLO-THRU is packaged in a standard TYVEK double aseptic transfer peel-back pouch. There are five FLO-THRU shunts of equal bulb size per carton.
