Device Description
The STERRAD® NX® 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 where the solution is heated and vaporized, introducing the vapor into the chamber under sub-ambient pressure and transforming the vapor into a gas plasma using electrical energy. The STERRAD NX Sterilizer has two cleared sterilization cycles, the Standard and Advanced Cycles. The sterilizer uses a disposable sterilant cassette that contains the 59% nominal hydrogen peroxide solution in a plastic cell pack and cassette shells. The hydrogen peroxide is concentrated before introducing into the sterilizer chamber and its concentration is monitored during the cycle. The sterilizer cancels the cycle if the hydrogen peroxide monitor data does not meet the specification. The hardware for the STERRAD NX Sterilizer consists of a sterilizer chamber, constructed with aluminum, and a variety of instruments and components which are housed in a covered frame. The sterilizer also uses accessories such as reusable instrument trays, printer paper, and an optional movable cart. The STERRAD NX Sterilizer can be placed directly on a table, counter top, or on the movable cart. The STERRAD® 100NX® 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 where the solution is heated and vaporized, introducing the vapor into the chamber under sub-ambient pressure and transforming the vapor into a gas plasma using electrical energy. The STERRAD 100NX Sterilizer has four cleared sterilization cycles (Standard, Flex, EXPRESS, and DUO Cycles). The sterilizer uses a disposable sterilant cassette that contains the 59% nominal hydrogen peroxide solution in a plastic cell pack and cassette shells. For the Standard and Flex Cycles, the hydrogen peroxide is concentrated before into the sterilizer chamber. For the EXPRESS and DUO Cycles, the concentration process is not used. For all four cycles, the hydrogen peroxide concentration is monitored during the cycle and the sterilizer cancels the cycle if the hydrogen peroxide monitor data does not meet the specification. The hardware for the STERRAD 100NX Sterilizer consists of a sterilizer chamber, constructed with aluminum, and a variety of instruments and components which are housed in a covered frame.

IV. DEVICE DESCRIPTION

STERRAD NX Sterilizer

The STERRAD NX 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 where the solution is heated and vaporized, introducing

6

the vapor into the chamber under sub-ambient pressure and transforming the vapor into a gas plasma using electrical energy. The STERRAD NX Sterilizer has two cleared sterilization cycles, the Standard and Advanced Cycles.

The sterilizer uses a disposable sterilant cassette that contains the 59% nominal hydrogen peroxide solution in a plastic cell pack and cassette shells. The hydrogen peroxide is concentrated before introducing into the sterilizer chamber and its concentration is monitored during the cycle. The sterilizer cancels the cvcle if the hydrogen peroxide monitor data does not meet the specification.

The hardware for the STERRAD NX Sterilizer consists of a sterilizer chamber, constructed with aluminum, and a variety of instruments and components which are housed in a covered frame. The sterilizer also uses accessories such as reusable instrument trays, printer paper, and an optional movable cart. The STERRAD NX Sterilizer can be placed directly on a table, counter top, or on the movable cart.

STERRAD 100NX Sterilizer

The STERRAD 100NX 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 where the solution is heated and vaporized, introducing the vapor into the chamber under sub-ambient pressure and transforming the vapor into a gas plasma using electrical energy. The STERRAD 100NX Sterilizer has four cleared sterilization cycles (Standard, Flex, EXPRESS, and DUO Cycles).

The sterilizer uses a disposable sterilant cassette that contains the 59% nominal hydrogen peroxide solution in a plastic cell pack and cassette shells. For the Standard and Flex Cycles, the hydrogen peroxide is concentrated before into the sterilizer chamber. For the EXPRESS and DUO Cycles, the concentration process is not used. For all four cycles, the hydrogen peroxide concentration is monitored during the cycle and the sterilizer cancels the cycle if the hydrogen peroxide monitor data does not meet the specification.

The hardware for the STERRAD 100NX Sterilizer consists of a sterilizer chamber, constructed with aluminum, and a variety of instruments and components which are housed in a covered frame. The sterilizer also uses accessories such as reusable instrument trays and printer paper.

Network Connectivitv

The STERRAD NX and 100NX are controlled by software running on an onboard microprocessor. The software is designed to control the sterilizer and provide an interface for user interaction with the sterilizer.

7

The software has the network connectivity feature that allows the Hospital IT Department to connect the STERRAD NX or STERRAD 100NX to a Hospital Local Area Network (LAN) for transfer of cycle parameters to a server and then, if desired, to an Instrument Tracking System. 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 basis for this 510(k) premarket notification is to offer the software revision that enables the network connectivity for the STERRAD NX and 100NX Sterilizers that were already placed on the market with the previous version of microprocessor. This proposed software revision includes the same software codes which were cleared for the systems under K142454 and has the same performance features as compared to the predicate devices as follows:

  • 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; and ●
  • It will notify the user of an unsuccessful transmission.

VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The subject devices have the same intended use, indications for use, materials, design features, and sterilizer functions as the predicate devices. Both the subject and predicate devices share the same technological characteristics with the exception of different versions of the microprocessor module.

The predicate devices use a later version microprocessor module due to the obsolescence of the previous version by the supplier. ASP plans to offer the software upgrade that enables the network connectivity for the subject devices, i.e., the STERRAD NX and STERRAD 100NX Sterilizers that were manufactured and distributed with the previous version of the microprocessor module.
