#### Substantial Equivalence:

The Tuttnauer autoclaves that are the subject of this 510(k) (EZ Plus Series autoclaves) are claimed to be substantially equivalent to the autoclaves cleared under K090783. K063711. K021504, and K993856. These predicate devices are equivalent in chamber size and general operation principles. The door design and software for the EZ Series autoclaves have been The nominal parameters (e.g., sterilization temperature and time: dry time; and changed. maximum/average cycle times) are not identical to those for the predicate devices, but follow ANSI/AAMI guidelines. The EZ Plus autoclaves and all predicate devices use steam as the sterilization agent.

#### General Description:

The EZ Plus autoclaves are autoclaves designed for sterilizing medical and surgical goods, including both wrapped and unwrapped, solid, hollow, and porous products and goods defined as hollow A (e.g., dental hand pieces; suction pipes) in ophthalmic, dental, and medical clinics; in first aid rooms; and in small laboratories. The device uses electrically generated heat to produce steam as the sterilizing agent. The device is equipped with multiple safety features. The door containing a safety locking mechanism that does not permit operation unless the door is closed, and does not permit the door to be opened until the internal chamber pressure is at atmospheric pressure. Additional EZ Plus safety features include an automatic safety shutoff to prevent chamber overheating; two (2) thermostats to detect overheating of the generator and the chamber; and a safety pressure valve for the pressure vessel. A digital display is used for monitoring and control purposes. There is an optional printer available to record cycle parameters.

Only United States Food and Drug Administration cleared accessories such as sterilization wraps, sterilization pouches, chemical indicators, biological indicators, and sterilization cassettes should be used with this autoclave.

## Design and Materials:

The EZ Plus Series autoclaves are steam sterilizer composed of a sterilization chamber, electronic heating elements, a clean water reservoir, housing, and control system. The EZ Plus Series is electronically controlled, and includes four pre-programmed sterilization cycles. All components in the sterilization path are constructed of grades of stainless steel that are deemed acceptable for steam sterilizers.

Indications for Use: The EZ Plus Series autoclaves are autoclaves designed for sterilizing medical and surgical goods, including both wrapped and unwrapped, solid, hollow, and porous products and goods defined as hollow A (e.g., dental hand pieces; suction pipes) in ophthalmic, dental, and medical clinics; in first aid rooms; and in small laboratories.

# Technology:

The EZ Plus Series autoclaves are steam sterilizers composed of a pressure vessel that utilize electric heating elements to produce the sterilizing agent, steam. These autoclayes contain an electronic control system that makes the device automatic and fully-configurable.

## Non-Clinical Testing:

Tuttnauer conducted validation studies in accordance with AAMI/ANSI ST55:2003. Testing shows that the EZ Plus Series autoclaves meet all aspects of the standard, including physical and microbiological performance requirements.

Since the EZ15 Plus autoclave is larger than provided under the table top standard of AAMI/ANSI ST55:2003, and since that standard therefore does not technically apply to the EZ15 Plus autoclave, Tuttnauer provides a summary of non-clinical testing performed for that model:

- . Sterilization efficacy validation testing according to AAMI ST8. Handpiece testing was conducted to AAMI ST55, even though the model size technically removes the device from this standard. Sterility was validated to a sterility assurance level of 10 using the biological indicator overkill method. The testing consisted of a one-half cycle tests based on each of the 4 pre-programmed sterilization cycles. Testing with a fully loaded chamber. The test loads included instruments such as handpieces and lumen devices in the appropriate cycles.
- . Thermal profile testing was conducted based on the AAMI ST8 guidelines. The testing was conducted using cycles based on the 4 pre-programmed sterilization cycles; however, in some cases, less air removal pulses were necessary to achieve the required sterilization temperature. Recorded temperature data demonstrated that the EZ15 Plus autoclaye achieves the appropriate temperatures throughout the sterilization chamber, and that these

temperatures can be maintained in a steady state during the exposure phase of the sterilization cycles.

- . Dry time testing was conducted based on the dry time tests outlined in AAMI ST8 and AAMI ST55 for wrapped cycles only (cycles 2 and 4). Testing included fabric wrapped instruments as well as paper/plastic pouch wrapped instruments. All results met or exceeded the minimum dry time criteria under the standards.
#### Conclusion:

The EZ9 Plus and EZ11 Plus autoclaves conform to all appropriate standards including the AAMI ST55 standard for table-top autoclaves. Additionally, as described in the summary comparison table, the characteristics of the autoclaves are substantially equivalent to the predicate devices in size, technology and operation. The EZ15 Plus also generally conforms to AAMI ST55 (except for chamber size) as well as AAMI ST8 for larger autoclaves. The testing to those standards is summarized above. The tests are appropriate for the EZ15 Plus based on intended use of the autoclave. The EZ15 Plus autoclave is also substantially equivalent in size, technology, and operation to the predicates summarized in the comparison table.

For all of the foregoing reasons, Tuttnauer believes that the EZ Plus Series autoclaves described in this 510(k) notification may be safely marketed in the United States.
