Patent AT-E400232-T1: [Translated] ELECTROSURGICAL SUCTION-ABLATION DEVICE

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Metadata Last Checked: September 07, 2025 | Last Modified: 2025-09-06
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 with an opening is assembled to the electrode-mandrel assembly in order to separate/isolate the protuberances from each other. The insulator is further provided with a cylindrical passage in communication and aligned with a radial passage of the mandrel.
