Description
The Avanos PMC21-50-4 is a Straight Radiofrequency (RF) Cannula used in interventional pain management. It serves as the insulated conduit for an RF probe to reach specific nerve tissues (such as the medial branch nerves of the spine) to perform thermal ablation, which interrupts pain signals.
The model number specifies its dimensions: 21 Gauge thickness, a 50 mm length, and a 4 mm active (uninsulated) tip.
Key Features
Targeted Thermal Lesioning: The 4 mm active tip allows for precise, localized heating of the target nerve without damaging a large area of surrounding tissue.
Straight Tip Design: A standard straight cannula is typically used for direct, posterior approaches where the clinician has a clear, linear path to the target nerve under fluoroscopy.
Integrated Insulation: The cannula body is fully insulated, ensuring that the radiofrequency energy is only delivered through the exposed 4 mm tip at the distal end.
Standard Gauge: The 21 Gauge diameter offers a balance between structural rigidity (to prevent bending during insertion) and patient comfort.
Sterile and Single-Use: Provided sterile to reduce the risk of cross-contamination and ensure the integrity of the insulation for every procedure.

Primary Uses
Facet Joint Denervation: Used to treat chronic back pain by ablating the medial branch nerves that transmit pain from the facet joints of the spine.
Sacroiliac (SI) Joint Pain: Can be used in RF neurotomy of the lateral branches for patients suffering from SI joint dysfunction.
Chronic Nerve Pain: Employed in various percutaneous nerve blocks where a long-term interruption of pain signals is required via thermal lesioning.
