Radiofrequency cannula are indicated for use in RF heat lesion procedures within in the field pain management.  Applications for Curved RF Cannula include RF lesions at the medial branch of spinal nerves, dorsal root ganglia, sympathetic nerves, and interdiscal nerves; both for continuous RF and pulsed RF lesions. RF cannula are available in a wide variety of standard lengths, active tips sizes, and gauges.  RF cannula are designed with radiolucent hubs with no-slip features for increased tactile sensitivity and for superior C-arm visualization.The RF cannula have a curved distal shape that reduces steering force through tissue for precise and efficient targeting. The curve also enables laying the curved tip along the medial branch or alternatively at a more oblique angle to the medial branch, depending on desired targeting approach.
