Device Story

STERRAD 100NX Sterilizer is a self-contained, stand-alone system for low-temperature sterilization of medical instruments. It utilizes a multiphase process: aqueous hydrogen peroxide injection into a vaporizer; introduction of vapor into a chamber under sub-ambient pressure; transformation into gas-plasma via electrical energy. The system includes a sterilization chamber, disposable sterilant cassettes, reusable instrument trays, and optional cart. It offers three cycles: Standard, Flex, and the EXPRESS cycle. The EXPRESS cycle is designed for surface sterilization of metal/nonmetal devices, including those with diffusion-restricted spaces and rigid/semi-rigid endoscopes without lumens. The device is operated in clinical settings to ensure instrument sterility, reducing infection risk. Healthcare providers load instruments into trays, select the appropriate cycle, and the system automates the sterilization process. Output is a sterilized instrument ready for clinical use.

Clinical Evidence

No clinical data. Bench testing only. Validation performed using an 'overkill' approach with G. stearothermophilus spores. Studies included dose response with anodized aluminum, surface and mated surface sterilization, bacteriostasis testing, in-use testing for general medical devices, simulated use testing, toxicity testing, chemical indicator functionality, and process reproducibility. All tests passed.

Technological Characteristics

Hydrogen peroxide gas plasma sterilization system. Operates via sub-ambient pressure vapor injection and electrical energy plasma transformation. Components include sterilization chamber, disposable sterilant cassette, and reusable instrument trays. Stand-alone system; can be placed on table or cart. Software-controlled cycles (Standard, Flex, EXPRESS).

Indications for Use

Indicated for low-temperature sterilization of metal and nonmetal medical devices, including instruments with diffusion-restricted spaces (e.g., hinged forceps/scissors), rigid/semi-rigid endoscopes without lumens, and specific stainless steel or polyethylene/Teflon flexible endoscopes.

Regulatory Classification

Identification

#### 4.0 DESCRIPTION OF DEVICE

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® 100NXTM Sterilizer has three different sterilization cycles, the Standard cycle, the Flex cycle, and the new optional additional EXPRESS cycle.

The hardware for the STERRAD® 100NX™ Sterilizer consists of a sterilization chamber and a variety of instruments and components which are housed in a covered frame. The sterilizer system also uses accessories such as a disposable sterilant cassette, reusable instrument trays, printer paper, and an optional movable cart. The STERRAD® 100NXTM Sterilizer can be placed directly on a table, counter top, or on the movable cart.
