Corrections: h8 - initial use of device was not checked.H10 - narrative was missing.One 6.5f destino twist steerable guiding sheath was received back from the customer without the dilator.There were no other accessories.Blood was found on and inside the sheath and sideport tubing.According to the event description summary, the doctor saw leakage between the handle and the sideport of the sheath.Upon evaluation of the returned sheath, it was found that the hub cap on the handle was crooked.Everything else looked normal.Glue residue was present on the sideport tubing/hub junction.The sheath was manually leak tested with the syringe connected to the stopcock and the tip occluded.The sheath exhibited slight leakage coming out from the handle when tested using this method.It was unclear exactly where the leakage came from.The sheath was then tested using the iso (b)(4) for liquid leakage test method.The device was occluded at the distal tip.The sheath did not hold the pressure at all.The sheath leaked immediately from the handle.It was uncertain if the leakage was coming from the sideport junction so the handle was removed.As soon as the handle was removed, the hub cap/valve assembly fell off.The sheath was iso leak tested again by occluding the distal tip and occluding the hub with the thumb.The sheath was pressurized to over 300kpa for 30 seconds and held pressure for the 30 second duration and there was no leakage from the sideport/hub junction.This concluded that the leak was coming from the hub cap/valve assembly.The cap was cracked in two areas and when viewed under a microscope; glue residue was present on the cap.The hemostatic valve looked normal with no anomalies.Returned device analysis revealed the sheath was within manufacturing specifications.The sheath leaked when tested here at oscor.It was concluded that the sheath was leaking from the dislodged cap/seal assembly, not the sideport as stated in the event description.A possible cause of leakage during use could have been the mishandling of ancillary device(s) in conjunction with the sheath that caused the hub cap to dislodge which led to leakage.A leak test is performed in-process on 100% of the sheaths.According to the dhr, the sheath passed all in-process and final inspection steps including visual, mechanical, dimensional and leak testing.No manufacturing defects were found.Per manufacturing procedure (non-peelable sheath final assembly): using glue dispensing tip place a ring of glue below the seal around the outer rim of the sheath hub.Place the bonded cap (appropriate color) with properly seated seal over the hub and secure it in the sheath assembly fixture.Visually inspect bonded caps after curing.Gap between bonded cap and hub should not exceed 0.020".Sheath should be free of damages and defects.Leak test cured sheath assemblies 100% per procedure.Per qa procedure (destino steerable guiding sheath in-process and final inspection): sample size: ansi z 1.4, gen level i, normal, aql 1.5 normal.Perform leak test according to procedures based on available leak tester.The leak test is performed by manufacturing personnel and is observed by quality assurance.Per ifu: aspirate all air from the sheath by connecting the syringe to the sideport.Gently aspirate blood through the sideport for sampling and to make sure the sheath is clear of air.Blood should aspirate freely through the sideport.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.
