Failure to achieve the expected six-log reduction in microorganisms following the disinfection process.

On 04/01 and 6/2022, the firm emailed an "Urgent Medical Device Recall" letter to customers and followed up with a hardcopy letter on 04/07-08/2022 via their Third Party contractor informing customers of a labeling update to correct the instructions for use for certain flexible urological endoscopes and advise that high-level disinfection should not be used as a method of reprocessing. Supplemental validation testing of the efficacy of the manual high-level disinfection process using CIDEX OPA was performed. Testing showed that required efficacy level of disinfection using CIDEX OPA was not achieved. To the extent included in the current applicable instructions for use, the following methods are being removed as reprocessing methods from the instructions for use of the affected endoscopes. +Manual High-Level Disinfection: -Cidex-OPA -Revital-Ox" RESERT (e.g., 2.0% Accelerated Hydrogen Peroxide solution). +Automated Endoscope Reprocessor: -Medivators AER -Reliance EPS -EvoTech ECR Customer Actions: 1. Immediately discontinue use of all high-level disinfection methods for reprocessing affected endoscopes. 2. The affected endoscopes should be sterilized after each use by one of the sterilization methods recommended in the instructions for use specific to each endoscope. 3. If your facility does not have access to a sterilization method recommended in the applicable instructions for use, immediately discontinue use of the affected endoscopes and return products to KARL STORZ. 4.
