APPLICATORS AND ACCESSORIES REPROCESSING INSTRUCTIONS Cleaning, Disinfection, Sterilization, Inspection, and Storage GM11011300
Each health care facility is responsible for assuring that their reprocessing methods provide safe and effective reusable applicators and accessories for use in their associated clinical settings.
Where conflicting national reprocessing requirements are encountered, these shall take precedence over the Varian methodologies specified herein. This is especially true for nationalized procedures or methods required for the inactivation of prions.
These instructions also provide directions for inspection of reprocessed applicators and accessories to determine when they have reached the end of their serviceable life and require replacement.
Introduction
These instructions are intended to provide general guidance for reprocessing Varian BrachyTherapy reusable applicators and accessories to prepare them for clinical use.
Cautions and Warnings CAUTION: Cleaning and disinfectant reagent instructions provided by the reagent manufacturer(s) must be strictly followed. Failure to follow the manufacturer’s instructions can be expected to degrade or damage the device materials and their ability to perform effectively and safely when reused.
The reprocessing instructions described herein have been validated for use by Varian Medical Systems. The validations were conducted according to the current relevant medical device regulatory standards and have demonstrated that Varian BrachyTherapy applicators and accessories processed according to the conditions specified within this document can be safely and effectively reprocessed for clinical use and reused as specified for use according to each product's labeling (or Instructions for Use (IFU)).
CAUTION: Cleaning caps are single use devices that can be used only once and then they must be discarded. A reused cleaning cap might not securely protect the applicator lumens, so liquid could enter which could lead to malfunction of or damage to the Varian afterloader.
Note: Instructions for Use for individual applicators
CAUTION: Cleaning caps are required for closing ClickFit™ connectors before manual cleaning and disinfection or machine cleaning operations can be performed to avoid liquid entering the lumens which could lead to malfunction of or damage to the Varian afterloader.
and accessories are included on the Varian BrachyTherapy Applicators and Accessories Instructions for Use CD (GM11010400).
Additional and specific reprocessing method details and precautions for individual applicators and accessories are also provided in the IFUs for those individual applicators and accessories. These instructions apply only to those applicators and accessories for which this document is referenced in the “Cleaning, Disinfecting and Sterilization” section of the individual IFUs.
CAUTION: An applicator that is not completely disassembled might become damaged beyond repair during cleaning, disinfection and sterilization. CAUTION: Varian BrachyTherapy devices are not suitable for exposure to highly basic (such as NaOH) or highly acidic (such as HCl) cleaning or disinfectant reagents. These conditions can be expected to degrade or damage the device materials and their ability to perform effectively and safely when reused.
The personnel, methods, equipment, and reagents used for reprocessing of reusable applicators and accessories all provide impact upon the levels of performance and effectiveness delivered by the reprocessing system employed.
Alternative methods for applicators and accessories reprocessing may be equally suitable for the reprocessing of Varian's reusable BrachyTherapy applicators and accessories.

CAUTION: Applicator lumens of Varian BrachyTherapy devices must not become contaminated by liquid, moisture or other contamination as this could lead to malfunction of or damage to the Varian afterloader.

APPLICATORS AND ACCESSORIES REPROCESSING INSTRUCTIONS Cleaning, Disinfection, Sterilization, Inspection, and Storage GM11011300 WARNING: Cleaning caps must be removed from all ClickFit™ connectors before autoclave sterilization is executed to assure the applicator lumens of the affected device are sterilized during the autoclave steam sterilization process. Failure to remove cleaning caps results in a non-sterile lumen which could lead to infection if patient contact occurs.
WARNING: Before Varian BrachyTherapy devices can be disinfected or sterilized, they must be effectively cleaned to allow disinfecting and sterilizing agents to make full contact with all critical (patient contact) surfaces. Failure to comply could result in patient infection.
Note: When sterilizing multiple applicators and
accessories in one sterilization load, ensure that the maximum sterilization load qualified for Varian BrachyTherapy applicator sets (6.0 kilograms or 13.2 pounds) is not exceeded.
These instructions apply only to products that are originally manufactured by Varian Medical Systems.
If a product is supplied without its instructions for use, or if there are concerns or questions about the proper reprocessing and sterilization methods required for Varian BrachyTherapy applicators and accessories, please contact Varian for information. Refer to the “Varian Customer Support” section below for more information.
Varian BrachyTherapy devices require proper cleaning, disinfection and/or sterilization before the first use and before each additional use.
WARNING: Devices labeled "single-use only" shall not be reprocessed for reuse. Failure to comply could result in patient infection.
WARNING: Proper disassembly of applicator parts is required to assure that all parts come in contact with the disinfecting and sterilizing agents. Failure to comply could result in patient infection.
Note: For determining the maximum number of times a device can be reused/reprocessed, check the individual IFU provided for each applicator.
Highly aggressive decontamination agents and methods required to reprocess applicators and accessories that may contact TSE infective agents are not recommended or approved for use with Varian BrachyTherapy applicators and accessories.
WARNING: Disinfecting applicators with Sekusept PLUS and Cidex® OPA without carefully rinsing with flowing purified water for one (1) full minute five (5) times can cause injury to the patient.
WARNING: If any fluid or liquid enters an inner lumen of an applicator during the cleaning process, flush it with purified water and then carefully dry the lumen using compressed air before autoclave sterilization is performed. Failure to comply could result in a non-sterile device and patient infection.
Varian BrachyTherapy devices are not typically used for treatment of patient tissues where they could be exposed to TSE (Transmissible Spongiform Encephalopathies) infective agents as defined by the WHO (World Health Organization) or RKI (Robert Koch Institute).
Reprocessing methods and reagents other than those specifically described in these instructions may be used by the clinical user. However, it is the responsibility of the user to validate the appropriateness of the alternative methods or reagents.
All Varian BrachyTherapy applicators and components require a thorough inspection for damage and/or wear before reuse to assure proper performance of the applicators and accessories is maintained.
General Information Note: A slight green discoloration of applicator parts may occur due to disinfection with Cidex® OPA. This discoloration does not affect the functionality of the applicator. Note: Sterilizer manufacturer operational instruc-
tions should always be followed.
