150 medical device reports received by FDA name the brand "Hiwire Nitinol Hydrophilic Wire Guide" (ocy endoscopic guidewire gastroenterology-urology); the manufacturer given most often on reports is Cook; received from March 2010 to May 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

9 reports arrived in the 12 months to August 2026, down 53% from 19 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (78%) and injury (22%); across all endoscopic guidewire, gastroenterology-urology reports (product code OCY) death is recorded in 0.2% and malfunction in 81.5%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are peeled/delaminated (50.7%), material separation (22.7%) and break (6%). The patient problems coded most often are foreign body in patient. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
