Intended Use

The Reliance Endoscope Processing System is intended for washing and high level disinfection of up to two manually pre-cleaned, immersible, reusable, heat-sensitive, semi-critical devices such as GI flexible endoscopes, bronchoscopes and their accessories. High level disinfection is achieved within the 50 - 57°C HLD Phase of the Endoscope Processing Cycle (4-minute generation sequence followed by a 6-minute exposure sequence).

Device Story

Electromechanical washer/high-level disinfector; processes up to two manually pre-cleaned, immersible, heat-sensitive endoscopes. Input: endoscopes, water, and Reliance DG Dry Germicide (single-use package). Operation: microprocessor-controlled cycles; automated dilution of dry germicide to generate peracetic acid in situ; circulation of solution through device lumens and exterior surfaces at 50-57°C; automated rinse with 0.2-micron filtered water; HEPA-filtered air purge. Used in clinical settings by healthcare personnel. Output: processed, high-level disinfected endoscopes; printed cycle summary. Benefits: automated, standardized reprocessing; reduced user exposure to chemicals; validated microbial efficacy; filter integrity monitoring ensures disinfection reliability.

Clinical Evidence

In-use study conducted in a US hospital. Three flexible endoscope types processed according to instructions. Triplicate evaluations showed no organisms recovered after processing. Bioburden levels on clinically used endoscopes prior to disinfection were as high as 10^8 CFU/device.

Technological Characteristics

Electromechanical washer-disinfector; microprocessor-controlled. Internal components: stainless steel and silicone. Energy source: electrical. Connectivity: printer output for cycle documentation; optional barcode reader. Filtration: 0.2-micron water filter; HEPA air filter. Sterilization/Disinfection: High-level disinfection via in situ generated peracetic acid. Cycle parameters: 50-57°C HLD phase.

Indications for Use

Indicated for washing and high-level disinfection of up to two manually pre-cleaned, immersible, reusable, heat-sensitive, semi-critical medical devices, including GI flexible endoscopes and bronchoscopes. Not for use on non-immersible or non-heat-sensitive devices.

Regulatory Classification

Identification

An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.

#### Certification to electromagnetic standards, continued: Non-clinical Tests: Limits and Methods of Processor CISPR 22 (1997) Measurements of Radio Performance, (equivalent to EN 55022:1998) Disturbance Characteristics of continued Information Technology Equipment The Reliance Endoscope Processing System was evaluated in an inuse study in a US hospital. Three flexible endoscopes representing the range of types indicated in the product labeling were used in clinical procedures and processed according to instructions for use. In triplicate Clinical Tests evaluations of each endoscope, no orqanisms were recovered after processing. Bioburden levels on the clinically used endoscopes after manual cleaning and before high level disinfection were determined to be as high as 108 CFU/device. The above data document that the Reliance Endoscope Processing System meets the FDA requirements of the quidance documents: • Content and Format of Premarket Notification [510(k)] Submissions for Liquid Chemical Sterilants/High Level Disinfectants (2000), and · Guidance on Premarket Notification [510(k)] Submissions for Conclusion Automated Endoscope Washers (1993). Conformity to the requirements of these quidances demonstrates the safety and effectiveness of the Reliance Endoscope Processing System. Based on the results of all testing conducted, this system is as safe and effective as the predicate devices.
