Indications for Use
The Revital-Ox PAA High Level Disinfectant Chemical Indicator is designed to determine whether the peractic acid concentration in the high-level disinfection (HLD) phase of the chosen reprocessing cycle of the enspire 300 Series AER employing Peracetic Acid (Revital-Ox PAA High Level Disinfectant) is above the minimum effective concentration (MEC) of 850 mg/L.
Device Story
Single-use chemical indicator strip; polypropylene substrate with reactive indicator ink patch; protected by clear, germicide-permeable laminate. Used in enspire 300 Series AER during high-level disinfection cycles. Operator places strip in processor; chemical reaction (oxidation) occurs upon exposure to peracetic acid. Visual color change from blue to grey/tan indicates peracetic acid concentration > 850 mg/L (Pass). Provides immediate visual confirmation of disinfectant efficacy for healthcare personnel; ensures proper reprocessing of endoscopes; reduces risk of inadequate disinfection.
Clinical Evidence
Bench testing only. Performance validated through comparative sensitivity/specificity studies, analytic sensitivity/specificity, post-processing stability (inside/outside processor), blind reader studies, contaminant effects, temperature extremes, and shelf-life/open-bottle stability testing. All tests passed.
Technological Characteristics
Polypropylene strip with proprietary indicator ink; clear, germicide-permeable laminate overlay. Mechanism: chemical oxidation resulting in color change. Dimensions/form factor: strip. Standalone device; no energy source or connectivity. Shelf life: 16 months; open bottle stability: 90 days.
Indications for Use
Indicated for use in the enspire 300 Series Automated Endoscope Reprocessor (AER) to verify that the peracetic acid concentration during the high-level disinfection phase meets the minimum effective concentration (MEC) of 850 mg/L.
Regulatory Classification
Identification
Biological sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor adequacy of sterilization. The device consists of a known number of microorganisms, of known resistance to the mode of sterilization, in or on a carrier and enclosed in a protective package. Subsequent growth or failure of the microorganisms to grow under suitable conditions indicates the adequacy of sterilization. Physical/chemical sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor one or more parameters of the sterilization process. The adequacy of the sterilization conditions as measured by these parameters is indicated by a visible change in the device.

Dear Gregory Land:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

VERIFY® Chemical Indicator for SYSTEM 1E Processor (K102217, as modified by K173428)
#### 3. Device Description
Revital-Ox PAA High Level Disinfectant Chemical Indicator is a single-use chemical indicator consisting of a polypropylene strip with indicator ink printed in a patch at one end. A clear, germicide-permeable laminate is applied over the reactive patch to protect the strip from damage during handling and to prevent the ink from leaching from the substrate.
One strip is used with each Cleaning and High-Level Disinfection (HLD) and HLD only cycle by placing the strip within the enspire 300 Series Automated Endoscope Reprocessor. At the end of the cycle, if the reactive patch has turned from the starting blue color to grey/tan, it was exposed to > 850 mg/L PAA min. which indicates an effective peracetic acid dose, i.e. 'Pass'.
#### 4. Indications for Use:
The Revital-Ox PAA High Level Disinfectant Chemical Indicator is designed to determine whether the peracetic acid concentration in the high-level disinfection (HLD) phase of the chosen reprocessing cycle of the enspire™ 300 Series AER employing Peracetic Acid (Revital-Ox™ PAA High Level Disinfectant) is above the minimum effective concentration (MEC) of 850 mg/L.
#### న్. Comparison to Legally Marketed Predicate Device:
The proposed and predicate devices are single use chemical indicators for use in monitoring peracetic acid concentration in reprocessing cycles. The differences between the proposed and predicate devices are limited to the processor the chemical indicator is used for, the peracetic acid concentration for color change, the endpoint color and shelf life.
