Event Description

It was reported that during a fenestrated endovascular aortic repair (fevar) procedure, the doctor introduced the tourguide in the patient and placed it in front of a renal artery to catheterize it.The doctor removed the wire and the sheath as usual.He turned the wheel to change the orientation and the proximal extremity but after a turn, everything stop working.He removed the tourguide and saw that the kevlar wire used to go through the layer of the tourguide was outside, meaning there was a hole in the sheath where the wire had protruded one centimeter outside of the sheath.To continue the procedure, he used another tourguide.There was no patient symptoms or complications reported.

Manufacturer Narrative

The device was used in treatment.The device history records were reviewed to confirm that the device passed all applicable inprocess and final inspections.The device was not returned for analysis, therefore, the exact cause of the product issue cannot be determined and the clinical observation could not be confirmed.However, following controls are in place to mitigate the reported product issue.Per procedure (destino steerable guiding sheath in-process and final inspection): sample size: 100%.Using a 10x microscope, inspect the liner.Using 10x microscope, verify pull wire is aligned properly with the grooves of the mandrel.Using a 10x microscope, verify braid is terminated and liner is not torn or nicked.Verify presence of adhesive at proximal end.Assure no braid wires are loose.Using a 10x microscope, inspect side port tube assembly for excessive glue at both joints.A bead of glue around the perimeter of the side port tube to hub joint is acceptable.Smeared glue on side port assembly is not acceptable.Manual tug test - using a metric ruler at a distance of 5mm to 10mm, check the integrity of the bond gluing with firmness gently pulling on both joints: sheath hub to side port tube and stopcock to side port tube.Per qa procedure (destino pull wire assembly): test will be performed in the pull tester for the anchor ring.Confirm the pull tester anchor ring parameters are in: time 3.0 sec, pounds 15 and cycle 0/3 for destino bidirectional and for destino twist are in time 3.0 sec, pounds 8 and cycle 0/3.Place the subassembly of the anchor ring at the base of the pull tester; assure the ring is correctly inserted in the ring adapter of the fixture.Take one of the wires and place into the wire clamp and tighten the screw with a twisting motion, ensure that the wire is tight enough so that when operating, the wire will not release.Press start to activate the test fixture which will cycle three (3) times.Release the wire from the wire clamp and insert the 2nd wire only for destino bidirectional, repeating steps c) and d).If there's any detached, reject the part and contact your supervisor.Per instructions for use (ifu): avoid subjecting the device to unusual stresses.The device should be stored at temperatures between 5° c and 30° c (41° f - 86° f).Handle the steerable sheath with care at all times.Do not use excessive force when inserting the steerable sheath into a vessel.At no time should the guidewire be advanced or withdrawn when resistance is met.No further follow-up is required.Based on the investigation, a capa is not required as findings did not identify a design, labeling or manufacturing non-conformity.In addition, there was no new failure mode identified and the risk remains acceptable.The event will be re-evaluated if additional information becomes available.Oscor will continue to monitor this event type and risk.Oscor inc.Is submitting the above report to comply with 21 cfr part 803, the medical device reporting regulation.The report is based upon information obtained by oscor inc.Which the company may not have been able to investigate or verify prior to the date the report was required by fda.This report does not constitute an admission that the device, oscor inc., or its employees, caused or contributed to the event described in this report.Nor does this report reflect a conclusion by fda, oscor inc., or its employees, that the report constitutes an admission that the device, oscor inc., or its employees caused or contributed to the event described in this report.
