The RFK Curved-Tip RF Cannula is indicated for use in RF heat lesion making procedures for the relief of pain. The Cannulae are available in a variety of standard lengths, tip exposures, and gauges, shown in the table, to accommodate different target sites. They have ergonomic, radiolucent hubs for ease of handling and for C-arm visualization. The hubs also have a luer
taper for fluid injection. The Cannulae have a curved distal shape. That facilitates steering the tip through tissue to place it at a desired target. It 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.

The 20 gauge Cannulae with 10 and 15 cm length come in either sharp or blunt tips. A Cannula is inserted with its stylet in place. When the tip is positioned at the target, the stylet is removed. The Cosman CSK-TC Electrode is inserted into the Cannula and connected to the Cosman RF Generator to begin stimulation and lesioning. The CSK-TC5, CSK-TC10, CSK-TC15, and
CSK-TC20 Electrodes fit the corresponding length RFK Cannulae.
