Indications for Use
The STERRAD® Sterilizers are designed for sterilization of both metal and nonmetal medical devices at low temperatures. Because the cycle operates within a dry environment and at low temperatures, it is especially suitable for instruments sensitive to heat and moisture.
Device Story
STERRAD® NX® and 100NX® are stand-alone hydrogen peroxide gas plasma sterilizers. They process medical instruments by injecting aqueous hydrogen peroxide into a vaporizer, introducing vapor into a chamber, and converting it to gas plasma via electrical energy. Systems are controlled by an onboard microprocessor. This update introduces network connectivity (TCP/IP, DHCP) allowing hospital IT to transfer cycle parameters to servers or instrument tracking systems. Users interact via the device interface; cycle data is available in PDF/CSV formats. The device is operated by hospital staff in clinical settings. The output (sterilized instruments) ensures patient safety by eliminating pathogens without toxic residue. The network feature provides automated documentation of sterilization cycles for hospital record-keeping.
Clinical Evidence
No clinical studies were conducted. Substantial equivalence is supported by bench testing, including electrical safety and electromagnetic compatibility (EMC) testing per CISPR 11, EN 60601-1-2, and IEC/EN 61010 standards, alongside software verification and validation.
Technological Characteristics
Hydrogen peroxide gas plasma sterilization system. Chamber/door constructed of aluminum. Uses 59% nominal hydrogen peroxide solution in cassettes. Features upgraded CPU and controller board. Connectivity via TCP/IP over LAN using DHCP. Software controls sterilization process and network data transfer. Sterilization via hydrogen peroxide vapor and plasma. Class II device.
Indications for Use
Indicated for sterilization of metal and nonmetal medical devices, including flexible endoscopes and instruments with diffusion-restricted spaces (e.g., hinged forceps/scissors). Specific lumen dimensions and load configurations apply per cycle (Standard, Advanced, Flex Scope, Express, Duo).
Regulatory Classification

The software has been designed for ease of configuration using Dynamic Host Configuration Protocol (DHCP). The cycle information will be available in Portable Document Format (PDF) and Comma Separated Values (CSV) formats and transmitted using Transmission Control Protocol/Internet Protocol (TCP/IP). The network digital information will be identical to the existing cycle information printed out by the devices after each cycle (PDF file) and the existing electronic delimited data (CSV file) that can be downloaded through the USB port.
The software revision has the following performance features:
- It can be configured automatically or manually ●
- . It will be activated only upon the request of the User
- Once it is activated, the User can turn it off and back on
- It will have diagnostic tools for network troubleshooting ●
- . It will notify the User of an unsuccessful transmission
The associated accessories include:

## VII. PERFORMANCE DATA
The following performance data were provided in support of the substantial equivalence determination.
## Biocompatibility testing
Since the cited changes to the predicate devices do not affect the design or materials of the devices, biocompatibility testing was not required.
## Electrical safety and electromagnetic compatibility (EMC)
The STERRAD® NX® and 100NX® Sterilizers with the upgraded CPU and controller board were tested for Radiated and Conducted Emissions according to the Standards shown in the table below. All test results passed the requirements of the Standards (Table 3).
{12}------------------------------------------------
| Test Description | Standard | Pass/Fail |
|---------------------|--------------------------------------------------|-----------|
| Radiated Emissions | CISPR 11:2009<br>(Amended by A1:2010)<br>Class A | Pass |
| Radiated Emissions | EN 60601-1-2:2007 Class A | Pass |
| Conducted Emissions | CISPR 11:2009<br>(Amended by A1:2010)<br>Class A | Pass |
| Conducted Emissions | EN 60601-1-2:2007 Class A | Pass |
Table 3: Testing of STERRAD® NX® and 100NX® Sterilizers for Radiated and Conducted Emissions
The STERRAD® NX® and 100NX® Sterilizers were evaluated for safety under the standards listed below. The testing, conducted to the set of standards, provided a standardized level of assurance that the system is electrically and mechanically safe when operated and maintained in accordance with the STERRAD® User Guide.
- CAN/CSA-C22.2 No.:61010-1/R: 2009; Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use.
- UL 61010-1/R: 2008-10; Standard for Safety for Electrical Equipment for Laboratory Use. ●
- IEC/EN 61010-1: 2001; Safety Requirements for Electrical ● Equipment for Measurement, Control, and Laboratory Use.
- IEC/EN 61010-2-240 Particular requirements for sterilizers and washer-disinfectors used to treat medical materials, First Ed., 2005
- IEC/EN 60601-1-2: 2007 CLASS A; Medical Electrical Equipment, Part 1: ● General Requirements for Safety, Section 2: Collateral Standard: Electromagnetic Compatibility
- EN 55011, Group I Class A limits, based on CISPR 11:2009, Group I Class A limits (subset of EN 60601-1-2)

## Software Verification and Validation Testing
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate " level of concern since prior to mitigation of hazards a failure of the software could result in Minor Injury, either to a patient or to a user of the device.
## Mechanical and acoustic testing
No additional mechanical testing was performed since the only change in the predicate devices was the upgraded CPU with controller board and the software upgrade.
## Animal Study
No animal studies were conducted.
## Clinical Studies
No clinical studies were conducted.
## VIII. CONCLUSIONS
The changes to the predicate devices were a software revision and the use of a newer version of the CPU with the associated control board. Software verification and validation performed with these changes demonstrated that the modified devices will perform as intended under the specified use conditions. Therefore Advanced Sterilization Products considers the STERRAD® NX® and STERRAD® 100NX® with revised software, CPU and controller board to be substantially equivalent to their predicates.
