If you are suffering from chronic lower back pain, neck stiffness, or persistent joint discomfort, radiofrequency neurotomy using the Avanos PMP-22-100C-SU may be the solution. This technology is specifically designed to target nerves causing facet joint syndrome, sacroiliac joint pain, and sciatica symptoms, providing long-term relief when conservative treatments fail.
The Avanos PMP-22-100C-SU, along with specialized models like the PMF22-100-10CS and CRKA-17-75-5.5, represents a suite of high-performance radiofrequency (RF) probes designed for targeted neurotomy and chronic pain management. These precision-engineered instruments are critical components in modern interventional pain medicine, allowing clinicians to deliver controlled thermal or pulsed energy to specific nerve tissues.
Manufactured by Avanos, a global leader in medical technology, these sterile, single-use probes are designed for seamless integration with compatible Avanos cannulae. By focusing on reliability and procedural accuracy, the PMP and PMF series help medical professionals achieve optimal patient outcomes in minimally invasive settings while maintaining the highest standards of infection control.
Core Technology: Advanced Radiofrequency Delivery
Avanos RF probes utilize high-frequency electrical current to create a localized thermal lesion or to modulate nerve activity. The PMP-22-100C-SU is specifically designed as a trocar-style probe, optimized for safe and efficient tissue penetration.
The technology focuses on impedance monitoring and temperature control. When connected to an RF generator, these probes provide real-time feedback, ensuring that energy is delivered precisely to the target nerve while sparing surrounding healthy tissue. The single-use design ensures that every procedure begins with a probe that has perfect structural integrity and a factory-calibrated electrical profile.
Mechanism of Action
The clinical efficacy of the Avanos RF system relies on a controlled thermal interface:
-
Insertion: The RF probe is inserted through a pre-placed Avanos cannula (trocar) to reach the target nerve site.
-
Localization: Clinicians often use sensory and motor stimulation through the probe to confirm correct placement near the target nerve.
-
Ablation/Modulation: The RF generator sends a high-frequency current through the active tip of the probe. This causes molecular friction in the adjacent tissue, raising the temperature to create a lesion (thermal neurotomy) or applying pulsed energy to interrupt pain signals (neuromodulation).
-
Completion: The probe is removed, and the single-use device is disposed of, eliminating the risk of cross-contamination.
Clinical Applications and Uses
The Avanos RF probe line is highly versatile, supporting a variety of interventional pain procedures including:
-
Medial Branch Neurotomy: For the treatment of chronic facet joint pain in the cervical, thoracic, and lumbar spine.
-
Sacroiliac (SI) Joint Denervation: Utilizing specialized probes like the CRKA series for managing SI joint syndrome.
-
Trigeminal Neuralgia: Precision targeting for craniofacial pain management.
-
Peripheral Nerve Ablation: Targeted energy delivery for chronic joint pain in the knees or hips (cooled or standard RF).
Key Advantages
-
Sterile and Single-Use: Maximizes patient safety and streamlines facility workflow by removing the need for reprocessing and sterilization.
-
Trocar Compatibility: The PMP-22-100C-SU is engineered for smooth insertion through standard 22-gauge cannulae, reducing procedural friction.
-
Enhanced Precision: Designed for high-fidelity electrical conductivity to ensure accurate stimulation and lesioning.
-
Broad Portfolio: Multiple lengths (e.g., 75mm, 100mm, 150mm) and gauges (22G, 17G, 16G) allow clinicians to customize the tool to the patient’s specific anatomy.
-
Consistent Reliability: New-condition probes eliminate the performance degradation often seen in reusable alternatives.
Technical Specifications

Frequently Asked Questions
What are the primary benefits of using single-use RF probes like the PMP-22-100C-SU?
Single-use RF probes ensure optimal infection control by eliminating the risks associated with inadequate sterilization. Furthermore, a new probe provides consistent electrical impedance and physical sharpess, which can be compromised in reusable probes over time. This leads to more predictable lesion sizes and improved patient safety.
Are Avanos RF probes compatible with generators from other manufacturers?
Avanos probes are specifically engineered and calibrated for use with Avanos (formerly Halyard/Kimberly-Clark) radiofrequency generators. While some adapters may exist, using the probes with the intended Avanos system ensures maximum accuracy in temperature monitoring and energy delivery, which is vital for safe neurotomy procedures.
What is the difference between the PMP and PMF series probes?
The PMP series typically denotes a “standard” RF probe often used in trocar-compatible setups for spinal neurotomy. The PMF series may feature different tip configurations or insulation patterns designed for specific tissue-targeting requirements. Clinicians should select the model that matches their cannula gauge and required lesion geometry.
Can the CRKA-17-75-5.5 be used for standard facet denervation?
The CRKA-17-75-5.5 is a 17-gauge component often associated with specialized RF applications, such as cooled radiofrequency or larger-volume lesions. While it can be used for various nerves, its larger diameter is typically reserved for specific anatomical sites like the sacroiliac joint or larger peripheral nerves.
How does the trocar design of the PMP-22-100C-SU assist in the procedure?
The trocar-style design refers to the probe’s ability to fit perfectly within a matching cannula. This ensures that the active tip of the probe extends exactly to the intended distance beyond the cannula insulation, allowing the surgeon to target the nerve with millimeter-level precision.
What should I do if the RF generator shows an impedance error with a new probe?
If a new Avanos PMP-22-100C-SU shows an impedance error, first check all cable connections. Ensure the neutral dispersive pad is properly attached to the patient. Because these are single-use sterile items, if the probe itself is faulty, it should be replaced to maintain procedural integrity and safety.
