The Nautica™ Intracoronary Shunt is specially designed to provide a bloodless operative field during vessel anastomosis procedure. The simple yet effective design temporarily allows the blood flow towards distal bypass route from anastomosis site in the vessel. The Nautica™ Intracoronary Shunt facilitates anastomosis during Coronary Artery Bypass Grafting & Beating Heart Surgery. Nautica™ Intracoronary Shunt is a radiopaque one piece device consisting of flexible silicon hollow shaft having bulb shaped tip. The radiopaque tag indicates diameter of the bulb & is attached to the shunt via suture. The Nautica™ Intracoronary Shunt is safe and easy for insertion & is removed from the vessel just prior to the completion of anastomosis.
