Senate HELP Committee ranking member Sen. **Patty Murray** (D-WA) says data recently released by FDA shows “alarmingly high rates of contamination in certain duodenoscopes, even after the device is cleaned.” In a 5/9 letter to OIympus, she says the data “raise serious questions about your company’s ability to ensure the health and safety of patients who undergo procedures using Olympus-manufactured closed-channel duodenoscopes.”

Murray asks for this information: 

- a copy of each medical device report Olympus has submitted to FDA related to contamination of a closed-channel duodenoscope between 1/2017 and 5/9;
- the rate of contamination for both high concern organisms and low to moderate concern organisms identified in interim results from FDA-ordered sampling studies;
- when Olympus projects it will complete both FDA-ordered postmarket surveillance studies;
- any analysis the company has conducted on interim findings from the surveillance studies;
- how Olympus plans to address the findings of the surveillance studies and what the company’s position is on whether closed-channel duodenoscopes remain safe for patient use;
- what feedback Olympus has received from users of its closed-channel duodenoscopes concerning the cleaning and reprocessing instructions or any issues related to device maintenance; and
- whether Olympus has engaged in any effort to redesign or modify the closed-channel duodenoscope to address concern about its ability to be properly cleaned.
