Intended Use

The SporView® Rapid Read Biological Indicator is intended to be used with the 3M Attest Auto-Reader to monitor the effectiveness of dynamic-air-removal (prevacum) steam sterilization cycles of 4 minutes at 132°C. The SporView Rapid Read Biological Indicator provides a final fluorescent result in 3 hours. An optional pH color change is observed after 48 hours.

Device Story

Self-contained biological indicator (BI) for steam sterilization monitoring; contains G. stearothermophilus spores and growth media in polypropylene vial. Device placed in sterilizer; after cycle, incubated in 3M 390 Auto-Reader. Principle: enzymatic detection of α-glucosidase generated by viable G. stearothermophilus. Successful sterilization results in no enzyme activity; failure results in fluorescence detected by reader within 3 hours. Optional 48-hour visual pH color change (purple to yellow) confirms growth of surviving organisms. Used by healthcare personnel to verify sterilization efficacy; provides rapid feedback for clinical decision-making regarding instrument sterility.

Clinical Evidence

Bench testing only. Testing included viable spore population assay, resistance characteristics (D-value ≥ 10s, Z-value ≥ 10°C), carrier/packaging material compatibility, 7-day holding time assessment, growth promotion, and reduced incubation time validation (3-hour fluorescent/48-hour pH). Compatibility with 3M 390 Auto-Reader confirmed. Full and fractional cycle testing demonstrated expected kill/survival performance.

Technological Characteristics

Self-contained biological indicator; polypropylene vial, vented cap, glass media ampoule, spore carrier. Contains ≥ 1.0 x 10^5 G. stearothermophilus spores. Sensing principle: enzymatic (α-glucosidase) fluorescence detection and pH-based colorimetric growth detection. Incubation at 60±2°C. Compatible with 3M 390 Auto-Reader.

Indications for Use

Indicated for monitoring dynamic-air-removal (pre-vacuum) steam sterilization cycles (4 minutes at 132°C) in clinical settings using the 3M Attest 390 Auto-Reader.

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.

### 1. Device Description

The SporView Rapid Read Biological Indicator is a self-contained biological indicator designed to be used with the 3M Attest 390 auto-reader to qualify or routinely challenge dynamic-airremoval (pre-vacuum) steam sterilization cycles of 4 minutes at 270°F (132°C).

The SporView Rapid Read Biological Indicator is composed of a polypropylene vial containing a spore carrier and media ampoule enclosed with a vented cap.

Similar to the predicate device, 3M's 1292 Rapid Read-Out Biological Indicator cleared under 510(k)s K090569 and K926364, the subject device contains ≥ 105 viable spore population of G. stearothermophilus. It utilizes the a-glucosidase system, which is generated naturally within growing G. stearothermophilus. A successful steam sterilization cycle will result in no growth of G. stearothermophilus. A failure in the sterilization cycle creates a fluorescence change, which is detected upon incubation in the 3M 390 Attest Auto-reader. This provides an enzymatic result in

3 hours to indicate a steam sterilization process failure. The biological indicator will also detect the presence of G. stearothermophilus organism by a visual color change reaction. Biochemical activity of the orqanism will produce acid by-products that cause the media to change color after 48 hours. A visual pH color change after 48 hours also indicates a steam sterilization process failure.

## 2. Indications for Use

The SporView Rapid Read Biological Indicator is intended to be used with the 3M Attest 390 Auto-Reader to monitor the effectiveness of dynamic-air-removal (pre-vacuum) steam sterilization cycles of 4 minutes at 132°C.

The SporView Rapid Read Biological Indicator provides a final fluorescent result in 3 hours. An optional pH color change is observed after 48 hours.

## 3. Comparison of Technological Characteristics with the Predicate Device

The subject device – SporView Rapid Read Biological Indicator and its predicate device – 1292 Rapid Read-Out Biological Indicator are substantially equivalent in that they both have the same intended use, fundamental technology and general performance. Both the subject device and the 3M 1292 Rapid Read Indicator have a spore carrier inoculated with the same organism. G. stearothermophilus. The subject and predicate Bls both utilize a a-glucosidase enzyme system, which is generated naturally within growing G. stearothermophilus organisms.
