Abstract
An assembly for radiofrequency ablation of tissue. A cannula includes a cannula hub and a cannula body including a cannula bend, a lumen, and side opening within an outer side of the cannula bend. An electrode includes an electrode hub and an electrode body dimensioned to be inserted within the lumen of the cannula body in at least first and second rotational orientations as indicated by registration of respective indicia on the cannula and electrode hubs. A distal section of the electrode body extends past the side opening of the cannula body in the first rotational orientation, and the distal section extends through the side opening in the second rotational orientation. The indicia of the cannula hub and the electrode hub may be indicative of the orientation of the cannula bend and an electrode bend, respectively. Methods of performing radiofrequency ablation of the tissue with the assembly are also disclosed.
