Abstract
A suction sleeve is configured to couple to the shaft of an RF device to evacuate hot gasses, fluids and/or other aspirates. The suction sleeve may be configured to be disposed coaxially around the shaft between the first end of the shaft and the work element (e.g., an RF cutting element) thereof. The suction sleeve defines a suction port and a plurality of openings near the work element, and is configured to enable suction in through the plurality of openings and out through the suction port.
