Indications for Use Abbott Medical radiofrequency (RF) electrodes are intended for use in the lesioning of peripheral nerve tissue.

Warnings ▪ ▪ ▪ ▪

Do not use in the central nervous system. Must be manually cleaned and sterilized before first and every use. It is important that the instructions for use, supplied with the generator, be read and understood before each use. Electrodes must not be bent when in use or when being cleaned or sterilized. Bending will seriously affect the normal characteristics and technical factors of the electrode.

Connections This RF electrode is designed for use with an Abbott Medical RF lesion generator. After connecting and before each use, ensure that there is a temperature reading between 35°C and 38°C (body temperature) on the lesion generator temperature indicator.

Disposable Cannula This RF electrode has been designed to be used with an Abbott Medical RF disposable cannula. Ensure that the correct length of disposable cannula is used.

RF Electrode Tip Position The tip of the RF electrode, when in the cannula, should be visible to the eye within the non-insulated tip of the cannula. This should always be checked with each cannula prior to use. WARNING: Always remove the electrode before positioning, repositioning, or removing a cannula. Failure to comply may cause damage to the electrode.

Expected Service Life The expected service life of the RF electrode is defined as 90 days or 45 cleaning and sterilization cycles, whichever comes first. The number and date of uses can be documented in the tracking card packaged with the device. The service life is influenced to a considerable degree by careful handling.

Handling Handle the electrode diligently and carefully, and use unconditional observance of these instructions for use to ensure the RF electrode performs as intended throughout the expected service life. Poor handling may seriously affect the normal characteristics and technical factors of the electrode.

Manual Cleaning Procedure (Before Sterilization) NOTE: Keep the electrode moist after use to facilitate cleaning. CAUTION: Operatives should wear appropriate levels of protective clothing. CAUTION: The effectiveness of the subsequent cleaning process depends on the removal of gross soil. Decontamination may be impaired by dried or coagulated tissue. Therefore, particular attention should be paid to removing all debris by following the recommended procedure. 1.

Wipe or rinse the RF electrode and RF probe cover (also called protective tube) with tap water at 30‑40°C (86‑104°F) prior to cleaning. 1

2.

Submerse the RF electrode and RF probe cover in lukewarm, blooddissolving enzymatic solution for a minimum of 30 minutes taking care not to immerse the connector end as damage to the product may occur. CAUTION: If the connector is inadvertently immersed, allow the solution to drain out of the connector by inverting it for a minimum of 30 minutes prior to sterilization.

3.

Thoroughly clean, rinse and remove gross matter; i.e., blood, mucous, tissue from the product until visually clean, using a disposable clean soft nonlinting cloth moistened with blood dissolving enzymatic cleaning solution and a sterile brush with rigid nylon bristles and/or a sterile syringe. Thoroughly pay particular attention to areas, like crevices, where soil may be shielded. 4. Using a disposable clean soft non-linting cloth, moistened with blood dissolving enzymatic cleaning solution, wipe the cable and connector thoroughly until the device is visually clean paying particular attention to areas, like crevices, where soil may be shielded. 5. Using lukewarm filtered water, rinse the product until there are no visible signs of the cleaning solution remaining. 6. Visually inspect the product for any remaining soil and repeat the above steps if necessary. Use of Ultrasonic Cleaners Do not use ultrasonic cleaners as damage to the product may occur and reduce the useful life of the product.

Sterilization Caution (Before Sterilization) Before sterilization, inspect the RF electrode, cable, and connector for any signs of damage or corrosion. Do not use if any damage or corrosion is observed. Caution (After Sterilization) After sterilization and before each therapy, plug the RF electrode into the lesion generator and ensure the readings of temperature are between 35°C and 38°C (body temperature) and valid impedance range based on generator model. Do not use if any of the readings are not within the specified ranges. If the generator does not display a correct body temperature or impedance reading, discontinue use of the RF electrode and dispose of appropriately. Steam Sterilization (Moist Heat) Procedure CAUTION: Ensure that the RF probe cover is in place over the RF electrode and that the cable does not contact the metal housing of the autoclave or other metal instruments during the cycle, as this may reduce the effective life of the product. NOTE: The following steam sterilization autoclave cycles have been validated for the sterilization of Abbott Medical reusable RF electrodes.

Wrapped (Porous Load) Kimgaurd 600 (1-ply polypropylene) wrap to be used or a similar FDA cleared wrap/pouch Pre-vacuum air removal sterilizer Temperature: 132°C (270°F) Exposure time: 4 minutes Do not use gravity system processing for wrapped products.

2

Unwrapped "Flash" (For Immediate Use Only) CAUTION: The product must be used immediately following unwrapped sterilization as sterility may not be maintained. Pre-vacuum air removal sterilizer Temperature: 132°C (270°F) Exposure time: 4 minutes Gravity displacement sterilizer Temperature: 132°C (270°F) Exposure time: 4 minutes

Drying Procedure Following 132°C (270°F) steam sterilization cycle for 4 minutes Minimum drying time: 30 minutes After drying, allow the electrode to cool down to room temperature before renewed use.

General Notes ▪

It is advised that sterilization equipment should have validation certification and performance qualification test undertaken of their process cycles for effective processing.

▪

Healthcare facilities should validate the process they use employing the actual equipment, wrapping methods, and operators that routinely process these products.

▪ ▪

Products are free of latex. RF probe covers are available for use with the applicable reusable RF electrode model.
