US Patent 12133676 Tissue ablation cannula assembly

An assembly for radiofrequency ablation of tissue. The assembly includes a cannula and an electrode. A cannula body includes a cannula bend, and a single side opening radially positioned on an outer side of the cannula body. The outer side may be opposite an inner side on which a tip terminates at a point. A cannula hub may include indicia on a face that corresponds to the inner side. An electrode bend of an electrode body may be formed at a same axial location along its length as the cannula bend is formed along the length of the cannula body. The electrode may include a thermocouple near a distal end of the electrode body to be either directed through the single side opening in a dual active tip mode, or seated in a distal section of the cannula body in a single active tip mode.
