Abstract

An apparatus includes a catheter having a flexible outer sheath and a flexible irrigation tube. The flexible outer sheath defines a first lumen. The flexible irrigation tube is positioned inside the first lumen and includes an inner layer and an outer coating layer. The inner layer is formed of a synthetic polymer compound and has a uniform cross-section with a hollow interior defining a second lumen. The outer coating layer is disposed around the inner layer. The outer coating layer is formed of a polymeric compound and includes first and second isomers. The first isomer is configured to carry a positive electric charge and the second isomer is configured to carry a negative electric charge.
