Pruitt F3 the Next Generation Balloon Shunt The Pruitt F3 Carotid Shunt is made with a new, more flexible material that is resistant to kinking, is color-coded for easy identification, and has 10% increased flow over the original Pruitt-Inahara® Carotid Shunt.* The Pruitt F3 Carotid Shunt is now available in a NEW 8F size. Features: Color Coding The common inflation lumen and depth markings are now blue, to highlight the inflation path leading from the blue stopcock to the blue balloon. New Safety Sleeve Color The safety sleeve is now tinted yellow to enhance visibilty and serves as visual que to promote the correct usage. Depth Markings Depth markings indicate the insertion length of the shunt for both the internal inflation lumen and external inflation lumen of the carotid shunt. Both the Pruitt F3 and Pruitt-Inahara Carotid Shunt are secured in the vessel using occlusion balloons that eliminate the need for clamps. This reduces vessel trauma and allows for the use of a small incision, minimal dissection, and a short arteriotomy. Plaque endpoints can be visualized because the balloon holds the artery open during the procedure. This is especially important with high stenoses, when clamps cannot be used. Eliminates the need for clamps. Safety balloon with a moveable plastic sheath minimizes risk of internal carotid artery balloon over-inflation (pressure diverted to the safety balloon). Blood flow and pressure monitoring can be performed through the T-port, along with infusion and flushing and removal of embolic particles. Any particles that enter on insertion of the shunt can exit through the side port.
