No
The device description explicitly states that the STERRAD® 100S Sterilizer is a "self-contained stand-alone system of hardware and software" and details the hardware components involved in the sterilization process.
Based on the provided text, the STERRAD® 100S Sterilizer is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is clearly stated as the "sterilization of both metal and nonmetal medical devices at low temperatures." This is a process applied to medical devices themselves, not a test performed on biological samples to diagnose a condition.
- Device Description: The device description details a system for sterilizing medical instruments using a hydrogen peroxide gas plasma process. This aligns with sterilization, not in vitro diagnostic testing.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Providing information for diagnosis, monitoring, or screening
- Using reagents or assays for testing
The STERRAD® 100S Sterilizer is a device used to prepare medical instruments for use, ensuring they are free from microorganisms. This falls under the category of a medical device used in the healthcare setting, but not an IVD.

Device Description
The STERRAD® 100S Sterilizer is a self-contained stand-alone system of hardware and software designed to sterilize medical instruments and devices, using a patented hydrogen peroxide gas plasma process. Hydrogen peroxide vapor is generated by injecting aqueous hydrogen peroxide into the vaporizer bowl where the solution is heated and transformed into a vapor, introducing the vapor into the process chamber under negative pressure and transforming the vapor into a gas plasma with radio frequency (RF) electrical energy.
The equipment (hardware) for the STERRAD® 100S Sterilizer is the same as that of the predicate device, the STERRAD® 100 Sterilizer. (Note that the STERRAD® 100S Sterilizer does contain two additional hardware features, an oil return valve, added for customer convenience; and a door position sensor and control.) The hardware consists of a sterilization chamber onto which is mounted a variety of instruments and components, housed in a covered frame. The system also uses accessories such as disposable sterilant cassettes, reusable instrument trays, printer paper and ink cartridges.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
VALIDATION TESTING: Testing was performed using the "overkill" approach.
PREVALIDATION TESTING:
- Test Organism: B. stearothermophilus
- Process Variables and Parameters: Rationale and Definition: A matrix experiment was performed that tested the process variables of chamber wall temperature and plasma power within specification limits. The study showed that process lethality was unaffected over the range of process parameters tested.
- Characterization of the Pre-Exposure Plasma Phase: was performed to evaluate the effect of Pre-Exposure Plasma on the overall process little= was results of the studies showed that there is very little sporicidal activity in the Pre-Exy. The Plasma phase alone or in combination with the Exposure 1 and Exposure 2 process phases of STERRAD® 100S PROCESS VALIDATION
- Demonstration of a Dose-Response Relationship to Increasing Hydrogen Peroxide Injection Volume: Dose-response testing was performed using various materials (representative of materials used in medical devices) as spore carriers. B. stearothermophilus spore death kinetics data obtained for each material tested demonstrate a positive "dose response" to increasing volume of hydrogen peroxide injected under bollf-cycle conditions in the STERRAD® 100S Sterilization process. There were no spore survivors on any material with an injection volume of 720 µL or greater under half-cycle conditions. The nominal hydrogen peroxide injection volume for the half-cycle is 1440 µL. This result demonstrates that the dose response observation is not limited to a singular BI substrate or system and in naces case >6 SLR were observed in a half-cycle exposure. These results validate a 10% SAL for a STERRAD® 100S Sterilizer full-cycle.
- Surface Sterilization of Medical Device Materials: Surface sterilization efficacy studies were performed in the STERRAD® 100S Sterilizer with various substrate materials representative of the material commonly used in re-usable mdical devices. Inoculated spore carriers (with at least 1 x 10^6 B. stearothermophilus endospores) made from these materials were placed in the STERAD® 100S Sterilizer validation load and then processed through the STERRAD® 100S Sterilizer at less than half-cycle conditions. Results of these studies demonstrate an SAL of at least 10^6 for medical device surface sterilization in the complete STERRAD® 100S sterilization process for all materials listed as recommended for use in the STERRAD® 100S Sterilizer.
- Mated Surfaces Sterilization: Half-cycle validation studies with mated biological indicator carriers were performed to demonstrate sterilization efficacy between mated surfaces of medical devices. Mated Bls with at least 1 x 10^6 B. stearothermophilus spores sandwiched in-between the mated metallic and polymer carriers were processed through the STERRAD® 100S Sterilization System at half-cycle conditions. An SAL of 10^6 was demonstrated for mated surface sterilization in the complete STERRAD® 100S Sterilization processs.
- Lumen Sterilization: Half-cycle and modified Total-kill Endpoint validation tests were performed using B. stearothermophilus endospores (>10^6 spores) inside stainless steel lumens (3 x 400 mm) placed within the STERRAD® 100S Sterilizer validation load of medical devices. There were no spore survivors after multiple half-cycles. These results demonstrate a SAL of 10^6 for the complete STERRAD® 100S Sterilization process. ASP has conducted an additional test for nonmetallic lumens of 6 x 310 mm, similar to the testing that was performed for the predicate device. Stainless steel coupons inoculated with at least 10^6 spores of B. stearothermophilus were placed in the center of 6 x 310 mm polyethylene lumens as a test system for devices containing lumens with inner diameters of 6 mm or larger and lengths of 310 mm or shorter. The samples were processed with a validation load in the STERRAD® 100S Sterilizer under half-cycle conditions. Three cycles were performed with ten test samples in each cycle. All test samples were sterile. This result demonstrates an SAL of 10^6 for plastic lumens with inner diameters of 6 mm or larger and lengths of 310 mm or shorter processed in the STERRAD® 100S Sterilizer.
- Tyvek-Mylar Pouched Device Sterilization: Half-cycle validation studies with 3 x 400 mm stainless steel straight lumens in Tyvek-Mylar pouches were performed to demonstrate sterilization efficacy with the STERRAD® 100S Sterilization System. The stainless steel lumens served to represent rigid stainless steel medical devices with lumens. Ten Tyvek pouched stainless steel lumens, with Bls (>10) B. stearothermophilus spores), were placed into a STERRAD® validation tray and processed through the STERRAD® 100S Sterilizer at half-cycle conditions. No spore survivors were observed with the half-cycle conditions.
- Bacteriostasis Testing: A bacteriostasis study was performed with carriers of various materials. The materials were placed in open glass petri dishes and exposed to full cycle conditions in the STERRAD® 100S Sterilization system. Following exposure, the carriers were transferred to TSB and were then inoculated with less than 10 colony-forming units of B. stearothermophilus spores. All test carriers/materials demonstrated the desired outgrowth within the 14 day incubation period. however neoprene required the addition of catalase. The test data indicate there is no bacteriostatic effect from the carriers processed through the STERRAD® 100S Sterilization System.
SUPPORTING MICROBIOLOGICAL TESTING - Sporicidal Microbiological Testing: AOAC Sporicidal Activity of Disinfectants tests using B. subtilis and Cl. sporogenes contaminated carriers (silk suture loops and penicylinders) were performed with the STERRAD® 100S Sterilization System. None of the carriers demonstrated growth.

After drying, the devices water (AOAC preparation) supplemented with 576 read of 100S sterilizer or by directly were treated of the sterilizer, i.e., without cleaning. Standard microbiological methods were used to determine the presence of surviving spores from each treatment. The results show that the STERRAD® 100S process is minimally affected by the presence of an The results show that the ollenge. Even if the user does not properly wash the devices, the organic and morganio enancing. Intirates highly resistant spores in a diffusion restricted sterinzer is bith offectry attentions of scissors. When the devices are properly washed (i.e., environmont sater as the matter for the STERRAD® 100S Sterilizer) then a 6.1 log reduction is shown for the process.
- In-Use Sterility Testing: Devices representative of surface-feature and lumen claims for the STERRAD® 100S Devices representant o or selected for sterility testing. Devices tested were used in routine surgeries at a local hospital and included stainless steel devices with open surfaces, mated or hinged surfaces and stainless steel lumened devices approximately 3 x 400 mm.
