20G 145mm Straight RF Cannula 10mm Active Tip for Lumbar Facet Joint RF Ablation

20G 145mm Straight RF Cannula for Lumbar Facet Joint RF Ablation

The 20G 145mm Straight RF Cannula is a single-use radiofrequency cannula designed for lumbar facet joint radiofrequency ablation. Its longer shaft provides reliable access to deeper lumbar targets, while the 10mm active tip creates a predictable lesion along the medial branch nerves for facet joint denervation. The cannula is compatible with standard RF lesion generators and is supplied sterile for single-patient use.

Key Features

• Designed for Facet Joint RF Ablation: Optimized for lumbar medial branch and facet joint radiofrequency denervation.
• 145mm Working Length: Extended shaft supports deeper lumbar access, including patients with higher body mass index.
• 10mm Active Tip: A larger active tip produces a more predictable lesion for reliable facet denervation.
• PTFE Insulated Shaft: Insulation minimizes collateral thermal spread along the shaft.
• Precise Sharpe Tip: A sharp 20G tip supports smooth tissue penetration with reduced deflection.
• Standard Connector: Compatible with standard RF lesion generators and electrodes.
• Sterile Single Use: EO sterilized and individually packed to reduce cross-contamination risk.

Clinical Applications

Indicated for lumbar facet joint radiofrequency ablation and medial branch denervation in the treatment of chronic low back pain.
