# Description of the CS Medical TEEClean® Automated TEE Probe Cleaner
Disinfector with TEEZyme® Cleaner and TD-5® or TD-8ª High-Level Disinfectants
The TEEClean® cleaner disinfector provides cleaning and high-level disinfection of transesophageal (TEE) ultrasound probes when used according to the operating instructions and when used with TEEZyme® enzymatic cleaner and TD-5® or TD-8 disinfectant. The TEEClean® cleaner disinfector iss for use only with TEEZyme®
enzymatic cleaner and TD-5® or TD-8® disinfectant. Thus, the TEEClean® cleaner disinfector, TEEZyme® enzymatic cleaner, and TD-5º or TD-8º disinfectant represent a dedicated system. Each soiled TEE probe is bedside cleaned to the TEE probe manufacturer's instructions before insertion into the TEEClean® cleaner disinfector. A fresh, unopened bottle of TD-5° or TD-8° disinfectant is loaded into the TEEClean® cleaner disinfector. The TEEClean® cleaner disinfector heats the TEEZyme®, soaks the
{4}------------------------------------------------
TEE probe, and thoroughly rinses the enzymatic cleaner off the TEE probe before the cleaning cycle is complete. The TEEClean® cleaner disinfector then heats TD-5® or TD-® disinfectant to 38°-40°C, soaks the TEE probe at least five (5) minutes, and then thoroughly rinses the disinfectant off the TEE probe before the disinfection cycle is complete. The TEEClean® cleaner disinfector prints a verification report indicating a successful cleaning and disinfection cycles as well as the time and the average temperature during the disinfection. The TEE probe is then removed from the TEEClean® cleaner disinfector and dried according to the TEE probe manufacturer's instructions. The TEEClean® cleaner disinfector is ready for a new cycle immediately after the preceding cycle is completed. Because a fresh bottle of TD-5% or TD-80 disinfectant is used with each cycle, no monitoring of the disinfectant's potency is required, nor is there any requirement for daily testing of the disinfectant solution.

The TEEClean® Verification and Validation Summary Report
{12}------------------------------------------------
and the associated qualification documents for the TEEClean® detail the successful completion of all requirements of the TEEClean® Master Verification and Validation Plan.
#### Electrical Safety Testing
The TEEClean® cleaner disinfector has been investigated and passed all testing in accordance with UL 61010-1, 3rd Edition; Standard for Safety, Electrical Equipment For Measurement, Control, and Laboratory Use; Part 1: General Requirements; Rev. April 29, 2016 and UL 61010-2-040, 2nd Edition; Standard for Safety, Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use Part 2-040: Particular Requirements for Sterilizers and Washer-Disinfectors Used To Treat Medical Materials: Rev. January 15. 2016
#### Biocompatibility
Rinsing studies were performed on the rinsing the TEE probe shaft receives from the TEEClean cleaner disinfector after cleaning. Measured concentrations of the enzymes (TEEZyme® Cleaner) were taken from the rinse water and were judged acceptable.
Rinsing studies were performed on the rinsing the TEE probe shaft receives from the TEEClean cleaner disinfector after high-level disinfection. Measured concentrations of the disinfectant aldehydes (glutaraldehyde for TD-5® disinfectant, ortho-phthalaldehyde for TD-8® disinfectant) were taken from the rinse water and were judged acceptable.
Cytotoxicity testing was performed on TEE probes reprocessed in the TEEClean® cleaner disinfector with TD-5 and TD-8°. All probes passed and were considered noncytotoxic.
#### Performance Testing
Disinfectant (TD-5 and TD-80) vapor exposure studies were performed in a room with zero air exchanges and showed the main vapor management filter has capacity for 12 months of use.
Automated Simulated use studies with TEEZyme® Cleaner were conducted in the TEEClean® cleaner disinfector. In all cases there was a measurable reduction of soils to levels to allow for subsequent, successful high-level disinfection.
Automated Simulated use studies with TD-5 and TD-8 were conducted in the TEEClean® cleaner disinfector. In all cases there was a measurably complete kill of microorganisms after TEE probe processing.
{13}------------------------------------------------
After routine clinical use, soiled TEE probes were subjected to cleaning and disinfection in the TEEClean® cleaner disinfector with TEEZyme® Cleaner and TD-5° or TD-8° disinfectant with standard operating parameters. In all cases there was a measurably complete kill of microorganisms after TEE probe processing.
### Conclusion:
Based on the intended use, technological characteristics and non-clinical performance data, the TEEClean® Automated TEE Probe Cleaner Disinfector with TEEZyme® Cleaner and TD-5 or TD-8 High-Level Disinfectants is as safe, as effective, and performs as well or better than the legally marketed predicate device TD 100% Disinfector with TD-5 and TD-8 High Level Disinfectants (K160921).
