Description
The Avanos PMF21-100-5 is a Straight Radiopaque Radiofrequency (RF) Cannula designed for interventional pain management procedures. It functions as a sterile, insulated guide that allows an RF probe to reach specific nerve targets for thermal ablation.
The model number specifies its dimensions: 21 Gauge thickness, 100 mm length, and a 5 mm active (uninsulated) tip.
Key Features
Precision 21-Gauge Profile: This gauge provides a balance between structural stiffness for accurate placement and a smaller diameter than the 18G or 20G models, minimizing patient discomfort and tissue trauma.
Focused 5 mm Active Tip: The shorter 5 mm tip creates a more localized thermal lesion. This is ideal for precision ablation where the target nerve is small or situated close to sensitive structures that must be avoided.
Radiopaque Platinum Band: Features a platinum marker at the distal end of the active tip. This provides high-contrast visualization under fluoroscopy (X-ray), allowing the clinician to precisely verify the location and length of the intended lesion.
Full Shaft Insulation: The shaft is covered in medical-grade insulation except for the 5 mm active tip. This ensures the radiofrequency energy is targeted exclusively at the nerve site, protecting the skin and non-target tissues.
Color-Coded Hub: The hub is color-coded for rapid identification (typically Light Blue or Blue for 21G) and features a textured surface for better tactile control during insertion.

Primary Uses
Lumbar Medial Branch Neurotomy: Used to treat chronic lower back pain by ablating the nerves of the facet joints, especially when a more focused lesion is desired.
Cervical Facet Denervation: Sometimes used in the neck for patients with larger anatomy where a 60 mm cannula is too short, but a thin 21G profile is preferred.
Peripheral Nerve Ablation: Ideal for targeting smaller peripheral nerves where the precision of a 5 mm tip increases the safety profile of the procedure.
