While using the perforator on the midas drill, it plunged into dura.It was used on top of skull.Easy access location, completely perpendicular with normal sound when using it.Dura was punctured by the perforator.It drilled through the skull and did not stop as it was supposed to, so it kept going and punctured the dura before the surgeon could pull up the device to prevent injury.Dura would have had to be punctured anyway for the biopsy, but the opening was made unnecessarily large by perforator.Dura would have had to be repaired after biopsy anyway with surgifoam.So, they did the same and repaired with surgifoam.No lasting effect or other post op treatment needed.The patient is fine, as expected after surgery, no changes from what would have been their condition if the injury didn¿t occur.

The perforator was received for evaluation.Dhr - lot j40z43 was reviewed - no manufacturing anomalies.Failure analysis: - visually inspected utilizing unaided eye - anomalies include heavy organic matter.- instruction for use (ifu) testing per procedure: unit was found to performed as intended.- functional test per procedure: was found to performed as intended.The root cause is undetermined and was unable to be confirmed in the complaint investigation.The root cause cannot be determined, as no issues relevant to the failure were noted from the evaluation.Between 05nov2019 and 30jun2020, approximately 2,200 mdrs submitted electronically by integra lifesciences via trackwise, integra's complaint handling system, were not received by cdrh due to a computer system issue.Within this time period, an error with integra's middleware, which facilitates communications between trackwise and the fda system, caused the complaint records to close and indicate we had received an acknowledgement 3 from the fda when we had not.Integra interpreted the acknowledgement as a successful submission; however, subsequent investigation revealed the acknowledgement 3 received was from our middleware and not from the fda (these acknowledgements have been retained as part of the documentation of the mdr).The malfunction was related to the relocation of the trackwise application to a new data center during the transition of integra's corporate headquarters from plainsboro, nj to princeton, nj.Previously, integra had been successfully receiving acknowledgements 1, 2, and 3 from the fda, and our records reflect these acknowledgements, including the date and time stamps.Capa pr 229048 and nc 20-011 have been opened by integra to further investigate the nonconformance and develop a corrective action plan.The middleware error has been corrected, and integra has filed mdrs since the correction and verified that the appropriate acknowledgements have been received from the fda.Integra is resubmitting all impacted mdr reports for the time period 05nov2019 through 30jun2020.Integra lifesciences contacted (b)(6), director of regulatory programs, office of product evaluation and quality and (b)(6), assistant director, mdr team, office of product evaluation and quality on july 8-9, 2020 to report these issues regarding mdr reports.
