Abstract
A cannula assembly for radiofrequency ablation of tissue. A cannula body includes a cannula distal section including electrically conductive material. A cannula bend is between proximal and distal sections, and a lumen extends between the proximal and distal ends. A side opening is within an outer side of the cannula body and opening into the lumen. A body is dimensioned to be inserted and seated within the lumen of the cannula. The body includes a body bend such that, depending on a rotational orientation of the body relative to the cannula body, a body distal section is seated within the lumen of the cannula distal section or extends out of the side opening. An electrically insulating sleeve may be disposed over the cannula body. Complimentary indicia on a cannula hub and a body hub provide an indication of the rotational orientation of the body relative to the cannula body.
