Abstract
An aspirating ablator of simple construction and low cost is disclosed. The aspirating ablator is provided with a mandrel connected to a tubular member which houses a suction assembly. An electrode having a rectangular ablation surface formed of multiple parallel ribs or protuberances is assembled onto the mandrel so that the ablation surface is parallel with the longitudinal axis of the mandrel. A ceramic insulator provided with an opening of rectangular shape is assembled to the electrode-mandrel assembly. The insulator is further provided with a cylindrical passage in communication and aligned with a radial passage of the mandrel.
