Intended Use
The Sterilucent SCBI is intended to be used as a standard method for frequent monitoring of the Sterilucent HC 80TT Sterilizer Cycles, when incorporated into a test pack. The Sterilucent Process Challenge Device (PCD) test pack is used for routine monitoring of the Sterilucent HC 80TT Sterilizer Lumen and Flexible Cycles. The Sterilucent PCD may also be used for performance qualification of the Sterilucent HC 80TT sterilizer Lumen and Flexible Cycles during initial installation, after relocation, major repairs or malfunctions, or after sterilization process failures. Both the Sterilucent Lumen Cycle PCD and the Sterilucent Flexible Cycle PCD are intended to have greater resistance than the stand alone SCBI. Both devices are designed to have increased resistance beyond the sterilization half-cycle, but complete inactivation upon exposure to the full cycle.
Device Story
Sterilucent SCBI and PCD test packs monitor Sterilucent HC 80TT hydrogen peroxide vapor sterilization cycles. SCBI contains Geobacillus stearothermophilus spores on quartz fiber disc in polypropylene vial. PCDs incorporate SCBI into test pack with diffusion restrictor (tube) to simulate worst-case sterilization load. Used in clinical settings to verify sterilization conditions; PCDs provide greater resistance than stand-alone SCBI. Healthcare staff place PCD in sterilizer; after cycle, SCBI is incubated to check for spore growth. Output indicates whether sterilization conditions were met. Benefits include ensuring effective sterilization of reusable medical devices, reducing risk of infection.
Clinical Evidence
No clinical data. Bench testing only. Testing performed per ANSI/AAMI/ISO 11138-1 and 11140-1. Validated SCBI resistance (D-value, survival/kill window), 24-hour holding time, 24-hour reduced incubation time, growth inhibition, population stability, and 12-month shelf life. PCD functionality confirmed via fractional kill at half-cycle and full kill at full-cycle.
Technological Characteristics
Biological indicator: G. stearothermophilus spores on quartz fiber carrier in polypropylene vial with Tyvek filter cap. PCD: Polymer vial with diffusion-restricting tube and external chemical indicator. Energy source: VHP. Sterilization monitoring via spore inactivation. Compliant with ANSI/AAMI/ISO 11138-1 and 11140-1.
Indications for Use
Indicated for routine monitoring and performance qualification of Sterilucent HC 80TT sterilizer Lumen and Flexible cycles. Used by healthcare personnel for sterilization process verification.
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 Peter Kalkbrenner:
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 Sterilucent SCBI is similar to the STERRAD CYCLESURE 24 Plus Biological Indicator (K140589), manufactured by MESA Laboratories (Bozeman. MT). The Sterilucent SCBI and predicate device are both single-use sterilization process indicators intended to monitor exposure to sterilization cycles utilizing VHP as a sterilant. Both devices have the same intended use, materials, specifications, and mode-of-action, and are manufactured using the exact same production methods.
The Sterilucent HC 80TT PCD (Lumen and Flexible) is similar to the Sterilucent PSD-85 PCD (Lumen and Non-Lumen), which is intended for use in routine monitoring of the Sterilycent PSD-85 sterilization cycles (K141312). Both devices are designed to increase resistance beyond that measured with a SCBI and to represent a challenge to the sterilization process that is equal to or greater than the routinely processed item that is most difficult to sterilize in each respective cycle (ref. AAMI TIR31:2008).
Performance testing was conducted to demonstrate the functionality of the Summary of Non-Clinical Testing (Bench): Sterilucent SCBI either alone or when incorporated into a PCD. Testing was completed in accordance with FDA Guidance ("Biological Indicator (BI) Premarket Notification [510(k)] Submissions" dated October 2007), ANSI/AAMI/ISO 11138-1, and/or ANSI/AAMI/ISO 11140-1. Resistance characterization of the SCBI was performed using a resistometer compliant with the requirements of ANSI/AAMI/ISO 18472. A summary of nonclinical

tests performed to demonstrate the safety and effectiveness of both the Sterilucent SCBI and PCD are as follows:

| SCBI Population Stability &<br>12-month Shelf Life | Demonstrate spore population is<br>maintained throughout the<br>labeled shelf life | Spore population remains<br>between 1.0-4.0 x 106<br>throughout | Passed |
| SCBI Integrated Chemical<br>Indicator Verification | Demonstrate compliance to ISO<br>11140-1 pass/fail criteria | ISO 11140-1 Section 8.7,<br>Table 6 | Passed |
| PCD Resistance<br>Characterization | Demonstrate test packs are more<br>difficult to sterilize than the<br>SCBI | Greater resistance as<br>demonstrated by fractional<br>kill | Passed |
| PCD Functionality | Demonstrate challenge to the<br>sterilization process is equal to<br>or greater than the most difficult<br>item routinely processed | Fractional kill at half-cycle;<br>all kill at full cycle | Passed |
| Summary of Clinical<br>Testing: | Clinical evaluations were not required and therefore are not submitted with<br>this 510(k). | | |
| Conclusions: | The conclusions drawn from the non-clinical tests demonstrate that the<br>subject device is as safe, as effective and performs as well as or better than<br>the legally marketed predicate device. | | |
