The EverFlow Dolphin Protect catheter is made with a copolymer coat and a microdomain surface that duplicates natural cell and protein surfaces. This uses a coating to keep blood activation in check and to keep the catheter from wearing out. It also creates a better sense of blood flow to make it work quickly. The Bismuth additive can also be added to the surface coating to make it able to handle antimicrobial protection without releasing any active agents in the process. The optimized flow also helps to keep the system running right with a good lumen design, thus enhancing the overall functionality of the device. The sidehole free tip also helps the patient by keeping clotting from being a threat and will keep catheter suction functions on the vessel wall. This makes the catheterization time a little longer and more likely to function right.
