Sterilization Type Temperature Time Gravity Displacement 270°F (132°C) 3 minutes Immediate Use Steam Sterilization Cycle (Flash) 270°F (132°C) 10 minutes 275°F (135°C) 3 minutes 275°F (135°C) 10 minutes The 3M™ Attest™ 1491 Super Rapid Readout Biological Indicator provides a final fluorescent result in 30 minutes. An optional visual pH color change result is observed in 24 hours.

Device Story

Device consists of self-contained biological indicator (BI) and auto-reader. BI contains Geobacillus stearothermophilus spores and media ampoule. During steam sterilization, spores are exposed to cycle conditions. Post-sterilization, BI is placed in 490 Auto-reader, which incubates at 56°C. Reader detects fluorescence generated by enzymatic hydrolysis of non-fluorescent substrate by a-glucosidase enzyme (produced by viable spores). Fluorescent signal indicates sterilization failure. Output provided within 30 minutes; optional 24-hour visual pH color change readout available. Used by healthcare personnel to verify sterilization process efficacy; ensures patient safety by confirming equipment sterility.

Clinical Evidence

No clinical data. Bench testing only. Performance validated per ANSI/AAMI/ISO 11138-1:2006 and 11138-3:2006. Testing confirmed >90% genetic similarity to G. stearothermophilus ATCC 7953, D-value compliance (≥10s at 132°C, ≥8s at 135°C), and population ≥10^6 spores. Reduced incubation time study demonstrated >97% alignment with 7-day conventional incubation for both 30-minute fluorescent and 24-hour visual readouts.

Technological Characteristics

Polycarbonate sleeve, spore carrier, media ampoule. Sensing principle: enzymatic fluorescence detection (a-glucosidase). Energy source: electrical (56°C incubation). Dimensions: self-contained vial. Connectivity: standalone. Sterilization: steam. Software: embedded firmware for fluorescence detection and temperature control.

Indications for Use

Indicated for monitoring gravity-displacement and immediate-use steam sterilization cycles at 132°C or 135°C with exposure times > 3 minutes. Used in clinical or healthcare settings to verify sterilization efficacy.

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.

#### Predicate Devices:

(21 CFR § 880.2800(a))

- 3MTM Attest™ 290 Auto-reader .

#### Description of Device:

The 3M™ Attest™ 1491 Super Rapid Readout Biological Indicator (hereafter referred to as the 1491 Bl) is a self-contained biological indicator designed to be used with the 3M™ Attest™ 490 Auto-reader (hereafter referred to as the 490 Auto-reader) to routinely challenge 270°F (132°C) and 275°F (135°C) gravity-displacement steam sterilization cycles having exposure times > 3 minutes in length.

The 1491 BI is composed of a polycarbonate sleeve containing a spore carrier and media ampoule, enclosed with a blue cap. On each 1491 BI is a chemical process indicator that changes color from rose to brown when exposed to steam.

The 1491 Bl is a further improvement over the current 3M Attest Rapid Readout technology. Both the Attest Rapid Readout BIs and the Attest Super Rapid Readout Bls utlize the a-glucosidase enzyme system, which is generated naturally within growing G. stearothermophilus spores. The a -glucosidase enzyme in its active state is detected by measuring the fluorescence produced by the enzymatic hydrolysis of a non-fluorescent substrate. The resultant fluorescent by-product is detected in the 490 Auto-reader. The detection of fluorescence upon incubation of the 1491 BI in the 490 Auto-reader indicates steam sterilization failure.

The 490 Auto-reader is designed to incubate at 56°C and automatically read the 1491 BI for a fluorescent result within 30 minutes. The 490 Auto-reader is also designed to allow further incubation of the 1491 BI for an optional visual pH color change of the growth media at 24 hours. Both the fluorescent readout at 30 minutes and the optional visual color readout at 24 hours met the FDA's requirement of > 97% alignment with the result after the conventional incubation time of 7 days.

# Indications for Use:

Use the 3MTM Attest™ 1491 Super Rapid Readout Biological Indicator in conjunction with the 3M™ Attest™ 490 Auto-reader to monitor the cycles below.
