Intended Use

The True Indicating Self-Contained Biological Indicator is intended for monitoring the efficacy of saturated steam sterilization processes. The True Indicating Self-Contained Biological Indicator has a validated reduced incubation time of 10 hours and may be used in the following steam sterilization cycles: 121°C, 30 minutes (Gravity) 132°C, 4 minutes (Pre-Vacuum) 135°C, 3 minutes (Pre-Vacuum)

Device Story

Self-contained biological indicator (SCBI) for monitoring steam sterilization efficacy. Device consists of polypropylene vial containing a 6-mm filter paper disc inoculated with Geobacillus stearothermophilus (ATCC 7953) spores and a glass ampule of nutrient broth with Bromocresol Purple pH indicator. User places SCBI in the most difficult area to sterilize; after cycle completion, user activates device by crushing the ampule to submerge the disc in media. Device is incubated at 55-65°C for 10 hours. Growth is indicated by a color shift from purple to yellow and/or turbidity, signifying sterilization failure. Absence of growth (media remains purple) indicates effective sterilization. Used in clinical or healthcare settings to verify sterilization cycle performance.

Clinical Evidence

Bench testing only. Testing performed per ISO 11138-1:2017 and ISO 11138-3:2017 standards. Results: Viable spore population 1.0-4.8 x 10^5; D121 ≥ 1.7 min, D132 ≥ 18 s, D135 ≥ 12 s; z-value ≥ 11.6. Reduced incubation time of 10 hours demonstrated >97% alignment with 7-day conventional incubation. Simulated use testing confirmed growth in abbreviated cycles and no growth in half/full cycles.

Technological Characteristics

Materials: Polypropylene vial/cap, glass ampule, paper filter carrier. Sensing: Biological indicator (Geobacillus stearothermophilus). Energy: Thermal (incubation 55-65°C). Dimensions: Not specified. Connectivity: None. Sterilization: Not applicable (device is a monitor). Software: None.

Indications for Use

Indicated for monitoring the efficacy of saturated steam sterilization processes in gravity and pre-vacuum 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.

Dear Thomas Riha:

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.

| Predicate Devices:<br>(Legally Marketed) | SporView® 10 Steam Self Contained Biological Indicator (K122024) |
| Device Description: | The True Indicating Self-Contained Biological Indicator (SCBI) consists of a 6 -<br>mm filter paper disc inoculated with Geobacillus stearothermophilus ATCC®<br>7953, at a minimum of 105 bacterial spores encased within a polypropylene cap,<br>and a polypropylene vial which includes a glass ampule hermetically sealed<br>containing a nutrient broth culture medium modified with a pH indicator,<br>Bromocresol Purple. |
| Indications for Use: | The True Indicating Self Contained Biological Indicator is Intended formonitoring<br>the efficacy of saturated steam sterilization processes. The True Indicating Self-<br>Contained Biological Indicator has a validated reduced incubation time of 10<br>hours and may be used in the following steam sterilization cycles: 121°C, 30<br>minutes (Gravity), 132°C, 4 minutes (Pre-Vacuum), and 135°C, 3 minutes (Pre-<br>Vacuum). |
| Operational<br>Principles: | Place an SCBI in the most difficult area to sterilize in a load. When the cycle is<br>complete, the SCBI is retrieved and activated by crushing the growth medium<br>ampule to engulf the disc within the bottom of the SCBI vial. |
| | The activated SCBI should be incubated at 55-65°C for a minimum of 10 hours.<br>The SCBI should be monitored for visible signs of growth. Growth is indicated by<br>a visual shift in color of the growth medium from purple to yellow, and/or the<br>presence of turbidity. The absence of growth, resulting in growth medium<br>remaining purple in color and/or no turbidity being visually present, indicates the<br>cycle was effective. |
