FDA's MAUDE database holds 931 reports that name the brand "Gore Dualmesh Plus Biomaterial" (mesh surgical polymeric), received between January 2010 and May 2026; the manufacturer given most often on reports is W L Gore & Associates. Spellings of one product vary from report to report.

5 reports arrived in the 12 months to August 2026, close to the 5 of 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 injury (99.8%) and death (0.2%); across all mesh, surgical, polymeric reports (product code FTL) death is recorded in 0.5% and malfunction in 2.5%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are insufficient device problem information (94%), patient device interaction problem (1.2%) and contamination (1%). The patient problems coded most often are hernia, adhesion(s) and obstruction/occlusion. 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."
