Device Facts

• Record ID: K090569
• Device Name: MODIFICATION TO: ATTEST RAPID READOUT BIOLOGICAL INDICATOR, MODE 1292
• Applicant: 3M Company
• Product Code: FRC · General Hospital
• Decision Date: Apr 29, 2009
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 880.2800
• Device Class: Class 2

Intended Use

Use the Attest 1292 RRBI to monitor: 1. 250°F (121°C) gravity steam sterilization cycles. 2. 270°F (132°C) vacuum assisted steam sterilization cycles.

Device Story

Biological indicator system for monitoring steam sterilization efficacy; utilizes Geobacillus stearothermophilus spores. Device detects enzyme alpha-glucosidase activity via fluorescence; enzymatic breakdown of non-fluorescent substrate produces fluorescence signal. Secondary detection method involves visual pH color change (purple to yellow) due to acid by-products of spore metabolism. Used in conjunction with 3M Attest 190/290 Auto-readers. Fluorescence change or color change indicates sterilization failure. Operated by healthcare personnel in clinical settings. Modification involves transition to lot-by-lot calculated survival/kill testing.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Biological indicator containing Geobacillus stearothermophilus spores. Dual-readout mechanism: fluorescence detection of alpha-glucosidase activity and visual pH-based colorimetric change. Designed for use with 3M Attest 190/290 Auto-readers.

Indications for Use

Indicated for monitoring steam sterilization cycles, specifically 250°F (121°C) gravity and 270°F (132°C) vacuum-assisted cycles.

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.

3M™ Attest™ Rapid Read-Out Biological Indicator (#1292), K926364

#### 4. Device Description:

The 3M™ Attest™ 1292 Rapid Readout Biological Indicator, RRBI, is a dual readout biological indicator system specifically designed for rapid and reliable monitoring of steam sterilization process when used in conjunction with the 3M™ Attest™ 190/290 Auto-readers.

The Attest 1292 RRBI detects the presence of Geobacillus stearothermophilus, (formerly known as Bacillus stearothermophilus), by detecting the activity of alpha-glucosidase, an enzyme present within the organism. The presence of the enzyme is detected by reading fluorescence produced by the enzymatic breakdown of a non-fluorescent substrate. This creates a fluorescence change, which is detected by the Attest 290 Autoreader. A fluorescence change indicates a steam sterilization process failure, The Attest 1292 RRBI also detects the presence of G. stearothermophilus organisms by a visual color change reaction. Biochemical activity of the G. stearothermophilus organism produces acid by-products that cause the media

to change color from purple to yellow. A visual pH color change also indicates a steam sterilization process failure. The 3M™ Attest™ Rapid Read-Out Biological Indicator is identical in design and performance specifications (with exception of the calculation of survival/kill) to the predicate device.

# 5. Indication For Use:

Use the Attest 1292 RRBI to monitor:

- 1. 250°F (121°C) gravity steam sterilization cycles.
- 2. 270°F (132°C) vacuum assisted steam sterilization cycles.

# 6. Description of Modification

The purpose of this filing is to move from a survival tested at 5 minutes and a kill tested at 15 minutes to a calculated survival/kill testing on a lot-by-lot basis.
