Additional Manufacturer Narrative
The following sections were updated in follow-up 1: b4, d9, g1, g3, g6, h2, h3, h6, and h10.The device was used in treatment.One 8.5f destino twist steerable guiding sheath was returned from the customer with the dilator.There were no other accessories.Blood was found on and inside the sheath.Before decontamination of the sheath, it was found that the blue hub cap was crooked and loosely seated on the hub.It could be confirmed that the cap had detached from hub; the cap and hub were inspected at a 30x magnification.The cap snap feature which is intended to serve as a mechanical joint holding the cap in place was found to be properly formed and within dimensional specification.Slight out of roundness was observed, but was not found to have any effect on the snap feature structural integrity.Light signs of discoloration were evidenced on the internal face of the snap cap, indicating prior contact with cyanoacrylate adhesive.Although presence of glue was not specifically evidenced, the discoloration marks are indicative of prior presence of the adhesive.Per procedure non-peelable sheath final assembly: glue is placed using a glue dispensing tip below the seal around the outer rim of the sheath hub.The bonded cap of appropriate color is seated properly over the hub and is secured with a sheath assembly fixture.The sheath is allowed to remain in the fixture for at least 2 minutes after securing the last sheath in the fixture.After it is removed from the fixture, ensure that there is no excess adhesive.After the fixture is removed, each sheath is laid flat on the table for a minimum of 15 minutes before proceeding.Sheath assemblies must remain undisturbed for a minimum of 15 minutes.Bonded caps are visually inspected after curing.Gap between the bonded cap and the hub should not exceed 0.020".Sheath should be free of damages and defects.Per procedure destino steerable guiding sheath in-process and final inspection: cap and seal are inspected and the results are registered on form.Sample size: ansi z 1.4, gen level i, normal, aql 1.5 normal leak test is performed according to procedure based on available leak tester.The leak test is performed by manufacturing personnel at 100% and is observed by quality assurance personnel.The instructions for use (ifu) informs the user: use the sideport, located at the handle, to inject contrast solution or flush the steerable sheath.The steerable sheath must be thoroughly flushed with either saline or heparinized saline and free of air prior to use to avoid air embolism to the patient.Aspiration and flushing of the sheath should be performed frequently to help minimize the potential for air embolism.For injecting or aspirating through the sheath, use the sideport only with stopcock.Prior to infusion, remove all air using the sideport.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.
