Abbott SL-C505-22 Radiofrequency 5cm 22G Cannula Curved

• Model: SL-C505-22
• Length: 5cm
• Gauge: 22G

The Abbott SL-C505-22 curved RF cannula is a single-use, disposable probe designed for percutaneous radiofrequency lesioning or ablation procedures, especially in pain management or neuromodulation. Its curved configuration allows the clinician to navigate anatomical contours and approach neural targets from nonstraight trajectories—helpful when direct linear approach is blocked by anatomy or adjacent structures. The presence of a 5 mm “ActiveTip” (i.e. the exposed electrode portion) concentrates RF energy at the distal tip, enabling precise, localized thermal lesions while minimizing spread to adjacent tissues.

With a 22G gauge and 5 cm shaft length, the SL-C505-22 strikes a balance between minimal invasiveness and adequate reach for many peripheral nerve targets. The insulated shaft ensures the RF energy is confined to the tip, reducing unwanted heating along the needle track. The curved shape, combined with a hub / connector interface suitable for standard RF generators, supports both accurate placement and practical utility in procedural settings. Vendor descriptions mention features such as a tapered tip for easier insertion, silicone insulation for smoother passage, and compatibility with thermocouple electrodes.

In clinical use, this type of cannula is advanced under imaging or guidance (e.g. fluoroscopy, ultrasound) to the target neural structure (e.g. dorsal root ganglion, medial branch, facet joint capsule). Once positioned, RF energy is delivered via the exposed tip to create a controlled lesion, interrupting nociceptive signal conduction. The curved profile can allow “bending around” obstacles or adjusting the approach angle without repositioning the entire instrument. Because it is disposable, the SL-C505-22 reduces concerns of sterilization damage or electrode wear. As always, safety features (impedance monitoring, temperature control, gradual ramping) should be followed per manufacturer instructions when using RF probes.
