A facility reported the surgical pattie (id 801404) string was lost during a surgery (posterior bilateral lumbar decompression at l2-5).The wound was irrigated and thoroughly searched.The room, drapes, gowns, back table, and trash containers were also inspected.The patties were moistened for an hour and was not altered or cut from original size prior to use.The patties were soaked during use.An x-ray was taken to ensure that the string was not inside the patient.The event did not led to a significant surgical delay, and as of right now, no adverse effect on the patient.

Updated fields: d4, d9, g3, g6, h2, h3, h4, h6, h11.The surgical pattie (b)(6) was not returned for evaluation as the product is not available for return as per customer.Lot number information has been provided; therefore, device history record (dhr) was reviewed, and no anomalies were found.The root cause(s) of the reported issue could not be determined.However, a probable root cause for the reported complaint may be related to inadequate weld strength of the string to the pattie's surface.If additional relevant information becomes available in the future, this complaint will be reopened, and the respective evaluation performed.Trends will be monitored for this and similar issues.At present, we consider this complaint to be closed.A corrective and preventative action (capa) was closed in august 2024 for the patties/strips product family related to x-ray polymer issues, string issues and incorrect count.Actions were implemented to minimize the issues above.
