No
Explanation: This device is an endoscope cleaner and reprocessor, designed for cleaning and disinfecting other medical devices (endoscopes), not for directly treating a patient's condition or disease.

No

The device is an endoscope cleaner and reprocessor, indicated for cleaning and high-level disinfection of semi-critical endoscopes. It processes medical devices rather than diagnosing patients.

No

The device description clearly states it is a "two-basin washer/disinfector" and describes its physical components and function in cleaning and disinfecting endoscopes, indicating it is a hardware device with integrated software.

Based on the provided text, the EVOTECH® ECR Endoscope Cleaner and Reprocessor is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use is to clean and high-level disinfect heat-sensitive semi-critical endoscopes. This is a process applied to medical devices (endoscopes) to prepare them for reuse, not a test performed on a biological sample to diagnose a condition or provide information about a patient's health.
  • Device Description: The device is described as a washer/disinfector that uses detergent and disinfectant to process endoscopes. This aligns with a device used for reprocessing medical equipment.
  • Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances in biological samples
    • Providing diagnostic information about a patient
    • Using reagents or assays for testing

The device's function is to clean and disinfect medical instruments, which falls under the category of medical device reprocessing, not in vitro diagnostics.

Summary of Performance Studies

The EVOTECH® ECR Endoscope Cleaner & Reprocessor was tested in K040883 using the standard array of tests defined in the FDA Guidance on Premarket Notification [510(k)] Submission for Automated Endoscope Washers, Washer / Disinfectors, and Disinfectors Intended for Use in Health Care Facilities, August, 1993.

For simulated use testing, the high level disinfectant indicated for use with the EVOTECH® ECR Endoscope Cleaner & Reprocessor was tested for efficacy in a simulated use environment. A 6 Log10 reduction of Mycobacterium terrae was achieved when flexible endoscopes, contaminated with Mycobacterium terrae and artificial soil and were exposed to CIDEX OPA Concentrate In Use solution without cleaning. The diluted CIDEX® OPA Concentrate at an MEC of 0.055% OPA concentration at 50°C is effective against Mycobacterium terrae in artificial soil.

For in use testing, endoscopes used in a clinical environment were reprocessed in the EVOTECH® ECR Endoscope Cleaner & Reprocessor without manual cleaning. Sterility testing demonstrated no growth.

For biocompatibility, an endoscope reprocessed in the EVOTECH® ECR Endoscope Cleaner & Reprocessor was evaluated for residue levels. The analysis indicates that the level of OPA residual remaining on an endoscope is not likely to cause toxic effects in humans.

For material compatibility, the EVOTECH® ECR Endoscope Cleaner & Reprocessor using CIDEX OPA Concentrate In-Use solution was evaluated for its effect on materials commonly used in medical devices. Multiple disinfection cycles over extended periods of time resulted in minimal effect on the test articles. The effects seen were similar to those seen with the predicate device for the high level disinfectant - CIDEX OPA Solution K991487.

The EVOTECH® ECR Endoscope Cleaner & Reprocessor was further tested in K061889 to determine its ability to high level disinfect and clean endoscopes. Both simulated use and in-use studies were completed. In both instances, endoscopes were contaminated and then processed in the "wash only" cycle in the EVOTECH® ECR Endoscope Cleaner & Reprocessor. Residual soil was quantified for both protein and total organic carbon (TOC). In all instances the residuals were below the predefined limit of 8.5ug/cm².

Additionally, because the wash cycle is intended to eliminate the need for manual cleaning. studies were completed comparing the residual soil after manual cleaning according to the procedures of the Society for Gastroenterology Nurses and Associates (SGNA) and cleaning in the EVOTECH® ECR Endoscope Cleaner & Reprocessor. In a non-inferiority trial, the washing of endoscopes in the EVOTECH® ECR Endoscope Cleaner & Reprocessor was determined to be noninferior to washing of endoscopes following the SGNA procedure.

Endoscopes used in clinical procedures were processed through the "wash only" cycle of the EVOTECH® ECR Endoscope Cleaner & Reprocessor and then extracted for residual organic material. Processing in the EVOTECH® ECR Endoscope Cleaner & Reprocessor reduced the residual protein and TOC in all channels and surfaces to less than the predefined acceptance criteria, indicating that the EVOTECH® ECR Endoscope Cleaner & Reprocessor can clean clinically used endoscopes.

High-level disinfection of cleaned endoscopes was achieved. Endoscopes were contaminated with Mycobacterium terrae imbedded in soil. Soil was inoculated in channels and on the surfaces of endoscopes so that each endoscopes contained ≥8.5ug/cm² protein with >10' cfu/mL M. terrae. Endoscopes were disinfected in the EVOTECH® ECR Endoscope Cleaner & Reprocessor without manual or automated washing. After processing the contaminated endoscopes through the disinfect cycle only in the EVOTECH® ECR Endoscope Cleaner & Reprocessor, there was a >10° reduction in M. terrae.

Further high level disinfection testing and quantitative tuberculocidal testing have been completed for this submission demonstrating effectiveness of the OPAC solution at 0.042% concentration in the presence of 5% fetal bovine serum organic soil load within 5 minutes at 50-52°C using CIDEX OPA-C solution.

2. PREDICATE DEVICES

  • . EVOTECH® Integrated Washer Disinfector (K082392, cleared November 13, 2008)

3. DESCRIPTION OF DEVICE

The EVOTECH® ECR Endoscope Cleaner & Reprocessor is a two-basin washer/disinfector utilizing an enzymatic detergent and a concentrated high-level disinfectant, CIDEX OPA Concentrate Solution. Both the detergent and high-level disinfectant are diluted in the system to in-use concentrations. The EVOTECH® ECR Endoscope Cleaner & Reprocessor is capable of cleaning endoscopes that have not been manually cleaned prior to placing in the system.

4

Endoscopes that have been qualified for processing in the EVOTECH® ECR Endoscope Cleaner & Reprocessor must go through manual bedside pre-cleaning according to SGNA and facility guidelines prior to being placed in the EVOTECH® ECR Endoscope Cleaner & Reprocessor for automated cleaning and/or high level disinfection. If automatic cleaning is not available or desired for the device by the user, the endoscope must also be manually cleaned by the user prior to being placed in the EVOTECH® ECR Endoscope Cleaner & Reprocessor.

After the endoscopes are connected to the EVOTECH® ECR Endoscope Cleaner & Reprocessor, the detergent is sprayed onto the surface of the device, and pumped through the lumens of the device, at sufficient pressure levels to remove any soil present on or in the device.

The disinfectant is then mixed with incoming water, which is monitored to ensure that the water temperature is then sprayed onto the surface of the device, and pumped through the lumens of the device, at sufficient time and temperature to achieve high level disinfection of any microorganisms. The temperature is monitored to ensure operating parameters of 50°C are met. A sample of the diluted CIDEX OPA Concentrate solution is extracted to ensure minimum effective concentration levels have been achieved. Following disinfection, the endoscopes are rinsed by the machine and air pumped through the lumens to facilitate drying of the endoscope. If selected by the user, an alcohol flush cycle may also be run to facilitate drying of the endoscope. The endoscope may then be removed, dried and used. The onboard printer generates a cycle printout summarizing the cycle results for the user's records.

The machine has built in safety features which cancel the cycle and notify the user if parameters are not met. These notifications, their causes, and next steps for the user. are defined in the EVOTECH® ECR Endoscope Cleaner & Reprocessor User Guide.

7. SUMMARY OF NONCLINICAL TESTS

The EVOTECH® ECR Endoscope Cleaner & Reprocessor is a washer/disinfector for use with an enzymatic detergent and the high-level disinfectant CIDEX® OPA Concentrate Solution at 50° with an exposure time of 5 min to achieve cleaning and high-level disinfection of flexible endoscopes.

The EVOTECH® ECR Endoscope Cleaner & Reprocessor was tested in K040883 using the standard array of tests defined in the FDA Guidance on Premarket Notification [510(k)] Submission for Automated Endoscope Washers, Washer / Disinfectors, and Disinfectors Intended for Use in Health Care Facilities, August, 1993.

For simulated use testing, the high level disinfectant indicated for use with the EVOTECH® ECR Endoscope Cleaner & Reprocessor was tested for efficacy in a simulated use environment. A 6 Log10 reduction of Mycobacterium terrae was achieved when flexible endoscopes, contaminated with Mycobacterium terrae and artificial soil and were exposed to CIDEX OPA Concentrate In Use solution without cleaning. The diluted CIDEX® OPA Concentrate at an MEC of 0.055% OPA concentration at 50°C is effective against Mycobacterium terrae in artificial soil.

For in use testing, endoscopes used in a clinical environment were reprocessed in the EVOTECH® ECR Endoscope Cleaner & Reprocessor without manual cleaning. Sterility testing demonstrated no growth.

For biocompatibility, an endoscope reprocessed in the EVOTECH® ECR Endoscope Cleaner & Reprocessor was evaluated for residue levels. The analysis indicates that the level of OPA residual remaining on an endoscope is not likely to cause toxic effects in humans.

For material compatibility, the EVOTECH® ECR Endoscope Cleaner & Reprocessor using CIDEX OPA Concentrate In-Use solution was evaluated for its effect on materials commonly used in medical devices. Multiple disinfection cycles over extended periods of time resulted in minimal effect on the test articles. The effects

8

seen were similar to those seen with the predicate device for the high level disinfectant - CIDEX OPA Solution K991487.

The EVOTECH® ECR Endoscope Cleaner & Reprocessor was further tested in K061889 to determine its ability to high level disinfect and clean endoscopes. Both simulated use and in-use studies were completed. In both instances, endoscopes were contaminated and then processed in the "wash only" cycle in the EVOTECH® ECR Endoscope Cleaner & Reprocessor. Residual soil was quantified for both protein and total organic carbon (TOC). In all instances the residuals were below the predefined limit of 8.5ug/cm².

Additionally, because the wash cycle is intended to eliminate the need for manual cleaning. studies were completed comparing the residual soil after manual cleaning according to the procedures of the Society for Gastroenterology Nurses and Associates (SGNA) and cleaning in the EVOTECH® ECR Endoscope Cleaner & Reprocessor. In a non-inferiority trial, the washing of endoscopes in the EVOTECH® ECR Endoscope Cleaner & Reprocessor was determined to be noninferior to washing of endoscopes following the SGNA procedure.

Endoscopes used in clinical procedures were processed through the "wash only" cycle of the EVOTECH® ECR Endoscope Cleaner & Reprocessor and then extracted for residual organic material. Processing in the EVOTECH® ECR Endoscope Cleaner & Reprocessor reduced the residual protein and TOC in all channels and surfaces to less than the predefined acceptance criteria, indicating that the EVOTECH® ECR Endoscope Cleaner & Reprocessor can clean clinically used endoscopes.

High-level disinfection of cleaned endoscopes was achieved. Endoscopes were contaminated with Mycobacterium terrae imbedded in soil. Soil was inoculated in channels and on the surfaces of endoscopes so that each endoscopes contained ≥8.5ug/cm² protein with >10' cfu/mL M. terrae. Endoscopes were disinfected in the EVOTECH® ECR Endoscope Cleaner & Reprocessor without manual or automated washing. After processing the contaminated endoscopes through the disinfect cycle only in the EVOTECH® ECR Endoscope Cleaner & Reprocessor, there was a >10° reduction in M. terrae.

Further high level disinfection testing and quantitative tuberculocidal testing have been completed for this submission demonstrating effectiveness of the OPAC solution at 0.042% concentration in the presence of 5% fetal bovine serum organic soil load within 5 minutes at 50-52°C using CIDEX OPA-C solution.

8. OVERALL PERFORMANCE CONCLUSIONS

Data presented in this submission indicate that the EVOTECH® ECR Endoscope Cleaner & Reprocessor is substantially equivalent to the Predicate Device.
