Description
The Avanos PMF20-145-10CS is a Radiopaque Curved Sharp Radiofrequency (RF) Cannula. This specialized needle is designed for deep-access interventional pain management, serving as an insulated guide for an RF probe to deliver thermal energy to target nerves.
The "CS" suffix stands for Curved Sharp, distinguishing it from blunt-tip versions.
The model number specifies its dimensions: 20 Gauge thickness, 145 mm length, and a 10 mm active (uninsulated) tip.
Key Features
Extended Reach (145 mm): This length is specifically engineered to reach deep anatomical targets or for use in patients with a larger body habitus where standard 100 mm needles cannot reach the target nerve.
Curved Sharp Design: The sharp, beveled tip facilitates easier penetration through tough ligaments and fascia. The curved shaft allows the clinician to "steer" the cannula around bony obstructions to achieve precise, parallel placement against the target nerve.
Integrated Radiopaque Marker: Features a high-visibility platinum band at the distal end of the active tip. This provides high-contrast visualization under fluoroscopy, allowing the clinician to confirm the exact location and span of the intended lesion.
Large Active Tip: The 10 mm active tip creates a broader thermal lesion. This larger "capture zone" is ideal for nerves with anatomical variability, increasing the likelihood of successful nerve ablation compared to smaller tips.
Medical-Grade Insulation: The shaft is fully insulated except for the 10 mm tip. This ensures that the radiofrequency energy is strictly localized to the target area, protecting the skin and surrounding healthy tissue from thermal damage.
Sure-Grip Hub: Features a color-coded hub (Yellow for 20G) with a textured surface for stable handling and immediate identification of the gauge size.

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 frequently used for SI joint procedures to cover larger lateral branch nerve paths at greater depths.
Thoracic Facet Denervation: Employed for middle and upper back pain where the curved tip helps negotiate the steep angles of the thoracic vertebrae.
Diagnostic Stimulation: Facilitates sensory and motor testing to confirm the cannula is correctly positioned before the permanent thermal lesion is created.
