Manufacturer Narrative

Additional mfg narrative-notes date of event not provided by the complainant, 510(k) k161000 previously k150594.A review of the device lot history records indicated the device was manufactured to specifications.The documented non-conformance would not have contributed to the reported feedback.A total of ten (10) devices was produced from the lot.A review of the cbi complaint database did not reveal any additional complaints associated with the reported lot number.A review of the ifu revealed that perforation and recurrence are amongst the list of potential complications that "are possible with the use of surgical device materials in otologic procedures." a direct root cause, to the reported perforation persistence and increase in size, is inconclusive.Factors that could contribute to the reported outcome include: patient¿s overall health, lack of viable tissue in area being treated, inadequate blood supply to the repair, graft too small for defect, user technique, and patient post-operative care of the treated area and overall post-op patient activities.The reported worsening of the patient¿s hearing is a secondary effect of the perforation persistence and/or increase in size.
