Description
Avanos PMF18-145-10
The Avanos PMF18-145-10 is a Straight Radiopaque Radiofrequency (RF) Cannula designed for interventional pain management. It serves as an insulated conduit used to guide an RF probe to a specific nerve target, typically in patients with a larger body habitus or for deep-seated anatomical targets.
The model number specifies its dimensions: 18 Gauge thickness, 145 mm length, and a 10 mm active (uninsulated) tip.
Key Features
Extended Reach: With a length of 145 mm, this cannula provides the extra depth required to reach nerves that standard 50 mm or 100 mm needles cannot access.
Integrated Radiopaque Marker: Features a high-visibility platinum band 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 span of the intended lesion.
Large Active Tip: The 10 mm active tip is designed to create a larger, broader thermal lesion. This increases the "capture zone," helping to ensure the target nerve is successfully ablated even with minor anatomical variations.
Medical-Grade Insulation: The entire shaft is insulated except for the 10 mm active tip. This ensures the RF energy is strictly focused on the target nerve while protecting the skin and surrounding healthy tissue.
Color-Coded Hub: Features a Pink hub (standard for 18G) for immediate gauge identification in the procedure room. The hub also has a "Sure-Grip" texture for stable handling and control during placement.

Package Contents
Each sterile, individually pouched unit includes:
1 Straight RF Cannula: The 145 mm insulated cannula with a 10 mm active tip.
1 Matching Stylet: A removable inner wire that maintains the needle's structural integrity and prevents tissue from entering the lumen during insertion.
Primary Uses
Deep Lumbar Facet Denervation: Used to treat chronic lower back pain by ablating the medial branch nerves in patients where the target is deeper than 10 cm.
Sacroiliac (SI) Joint Ablation: The 10 mm tip is ideal for targeting the lateral branches of the sacral nerves, which often require a larger lesion area for effective pain relief.
Splanchnic Nerve Blocks: Utilized for deep sympathetic nerve targets in the abdominal or thoracic regions.
Diagnostic Stimulation: Used to perform sensory and motor testing to confirm the cannula's proximity to the target nerve before applying thermal energy.
