The VASOSHIELD Pressure Controlling Syringe helps protect vessels from overdistension and potential endothelial damage during standard surgical preparation steps. It works by limiting the internal "flushing" pressure when harvested grafts are irrigated in preparation for use in Coronary Artery Bypass Graft surgery.
Avoidance of excessive pressure and limiting distension help maintain internal vessel integrity, which has been demonstrated to be an important factor affecting conduit quality and long-term graft patency.
Vessel flushing with uncontrolled pressure can result in injury to the endothelial lining of the conduit.1,2 Maintaining endothelial integrity preserves functions that enable vessels to maintain blood flow and resist occlusion.3,4
Now harvesters and surgeons can have consistent control over vessel distension—at any stage of the preparation process. Designed specifically to deliver the benefits of vessel flushing while controlling pressure, the VASOSHIELD Pressure Controlling Syringe effectively minimizes the risk of overdistension.
