Description
Avanos PMF20-100-10CB
The Avanos PMF20-100-10CB is a Radiopaque Curved Blunt Radiofrequency (RF) Cannula. This specialized needle is used in interventional pain management as an insulated guide for an RF probe to deliver thermal energy to target nerves.
The "CB" suffix stands for Curved Blunt. A blunt tip is often preferred in specific procedures to reduce the risk of accidental vessel or nerve puncture during final placement.
The model number specifies its dimensions: 20 Gauge thickness, 100 mm length, and a 10 mm active (uninsulated) tip.
Key Features
Curved Blunt Tip: The blunt tip is designed to provide an added layer of safety by pushing away sensitive structures (like blood vessels) rather than piercing them. The curved shaft allows the clinician to navigate around bony anatomy to place the active tip in the ideal orientation along the target nerve.
Integrated Radiopaque Marker: Features a high-contrast platinum band at the distal end of the active tip. This ensures precise visualization under fluoroscopy, allowing the clinician to verify the exact position and length of the intended lesion.
Large Active Tip: The 10 mm active tip creates a significant thermal lesion. This broader "capture zone" is useful for nerves with anatomical variability, helping to ensure the pain signal is successfully interrupted.
Medical-Grade Insulation: The entire shaft is insulated except for the 10 mm tip. This focuses the RF energy precisely on the target site while protecting the skin and surrounding healthy tissue from thermal damage.
Sure-Grip Hub: Includes a color-coded hub (Yellow for 20G) with a textured surface for better tactile control and easy gauge identification during a procedure.

Package Contents
The PMF20-100-10CB is typically sold in boxes of 10 units. Each sterile, individually pouched unit includes:
1 Curved Blunt RF Cannula: The insulated 20G cannula with a 10 mm active tip.
1 Matching Stylet: A removable internal wire that maintains the cannula's stiffness during the initial approach; once the target is reached, the stylet is removed so the RF probe can be inserted.
Primary Uses
Lumbar Medial Branch Neurotomy: Used to treat chronic lower back pain by ablating the nerves of the facet joints.
Sacroiliac (SI) Joint Ablation: The 10 mm tip is highly effective for covering the larger lateral branch nerve paths of the sacrum.
Thoracic Facet Denervation: Used for upper back pain where the curved tip helps navigate the thoracic vertebral angles.
Safety-Focused Procedures: Preferred in anatomical regions where the proximity of major blood vessels makes a blunt tip a safer choice for final positioning.
