Input: cleaned/rinsed medical devices (up to 75 lb). Output: terminally sterilized instruments. Subject device introduces ambient air ventilation instead of pressurized oxygen. Healthcare providers use sterilized instruments for patient procedures; ensures device safety by eliminating microbial contamination.

Clinical Evidence

Bench testing only. Validation performed using nine representative loads covering various instrument geometries (clamps, hinges, lumens, endoscopes) and packaging types. Verification confirmed residual sterilant levels meet acceptance criteria and compliance with IEC 61010-1, IEC 61010-2-040, and IEC 61326-1 standards.

Technological Characteristics

Dual-sterilant (H2O2/O3) low-temperature sterilizer; 125L chamber volume. Uses Omron PLC for software control. Critical parameters: differential chamber pressure, load temperature, wall/vaporization temperatures, exposure times, flow rates, and ozone concentration. Ventilation via ambient air. Complies with IEC 61010-1, IEC 61010-2-040, IEC 61326-1, and FCC Part 18/EN 55011.

Indications for Use

Indicated for terminal sterilization of cleaned, rinsed, and dried metal and non-metal reusable medical devices in health care facilities, including general instruments, flexible endoscopes (single, double, and multi-channel), and rigid/semi-rigid channeled instruments.

In contrast to the sterilization processes using H2O2 only and having multiple cycles, the STERIZONE® VP4 Sterilizer enables the sterilization of a wider range of instruments and load configuration with only one preset cycle. The dynamic system to distribute the sterilant ensures an adequate supply of the sterilant through multiple successive pulsed injections that adapt to the different load conditions (size, weight and temperature). The STERIZONE® VP4 Sterilizer offers a unique preset sterilization cycle (Cycle 1) to sterilize a wide range of loads consisting of general instruments, flexible endoscopes with one channel, double channels and multi-channels, and devices with rigid and semi-rigid channels, including rigid endoscopes with single or double channels. #### Technological Characteristics Comparison Table | Device Trade Name | Predicate STERIZONE VP4 Sterilizer K153689 | STERIZONE VP4 Sterilizer (with air vent option) K173694 | |------------------------------|---------------------------------------------------------------------------------|------------------------------------------------------------------| | Device Class | Class II | Same | | Product Code / Regulation | PJJ | Same | | Regulation Name | Dual sterilant sterilizer | Same | | Indications for Use | Terminal sterilization of reusable medical devices in health care facilities | Same | {10}------------------------------------------------ Image /page/10/Picture/0 description: The image shows a logo with the letters 'TSO' in blue, followed by a stylized molecular structure in gray.

The STERIZONE® VP4 Sterilizer has been designed, constructed and tested to meet the safety and performance requirements of applicable North American safety codes and international standards. The STERIZONE® VP4 Sterilizer complies with the applicable portions of the following standards: • IEC 61010-1 2004 Safety requirement for measurement, control and laboratory use - Part 1: General • IEC 61010-2-040 2005 Safety requirement for measurement, control and laboratory use Part 2 particular requirements for sterilizers and washer-disinfectors used to treat medical materials • IEC 61326-1: 2012 Electrical equipment for measurement, control and laboratory use - EMC requirements - Part 1: General requirements • Federal Communication Commission (FCC) Part 18 / EN 55011 | |----------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Risk Management | There was one potential risk [sterilant residual levels] identified due to the change of gas for final ventilation. However, verification testing showed that residuals were within acceptance criteria for previously cleared versions of the STERIZONE VP4. All potential hazards and failure modes identified during the design and development processes were addressed and did not impact the existing labeling. The risk management activities included application FMEA, design FMEA and manufacturing process FMEA. | | Conclusion | The results of the verification/validation tests and the risk analyses have demonstrated that the STERIZONE® VP4 Sterilizer (air vent option; K173694) is substantially equivalent to the STERIZONE® VP4 Sterilizer (K153689) |
