The catheter can then be re-inserted into the vessel to continue plaque removal using the same technique. The Tweezers are not intended to come into direct contact with the patient. The Stopcocks are standard, off the shelf accessories, used to facilitate the delivery of CO2 and saline to the catheter. The Syringes are connected to the Flush and Balloon Inflation Lumens (components on the catheter's handle assembly) via the Stopcocks. The Stopcocks are not intended to come into direct contact with the patient. Both the Tweezers and the Stopcocks are provided in order to make readily available these commonly used accessories and for user's convenience.
