One 10f arrive braided transseptal sheath was returned from the customer with the dilator.The sideport tubing/stopcock assembly was detached from the hub.There were no other accessories.No visible blood was found on or inside the sheath or dilator.According to the event description summary, the physician was about to put the transseptal needle into the sheath when the side arm/port detached from the sheath.Upon evaluation under a microscope, it was found that there was evidence of adhesive residue on the sideport tubing and on the hub stem.The device history records were reviewed to confirm that the device passed all applicable in-process and final inspections.Returned device analysis confirmed detachment of the sideport tubing.This can happen if the curing time of 4 hours is not fully reached and/or the units are handled or moved around during that time.The manufacturing procedure establishes that the units must remain still until curing time is fully reached.This means that the procedure may not have been followed as established.Retraining was conducted with manufacturing personnel on the applicable procedure to prevent recurrence of this issue.This issue was found to be an isolated event.Oscor will continue to monitor this event type and risk.Note: the tug test data was reviewed and all of the units in this lot passed.Per manufacturing procedure (non-peelable sheath sideport assembly) apply one drop of the adhesive on the pellethane side tube at a distance of 2- 3mm from the end.Spread the adhesive around the od of the tube by rotating the tube 360° while applying the drop of adhesive.Repeat the step by placing a drop of glue approximately 6-7mm from the same end, and spread the glue by rotating the tube while applying the adhesive around the od of the tube.Rotate the tube to ensure that the adhesive is applied all around the circumference of the tube uniformly.Fully insert the tube into the sheath hub sideport opening while rotating it 360°.Wipe away any excess adhesive sticking out of the sideport with a polywipe.After curing (undisturbed, for a minimum of 4 hours) test the joint of each part with a small tug, holding the tube in one hand and the stopcock in the other hand.Discard all parts that detach during the tug, do not attempt to cure parts again.Per qa procedure (introducer sheath, adelante breezeway, in-process and final inspection) sampling plan ansi z 1.4, gen level i, normal, aql 0.40 with the naked eye, inspect sideport tube assembly for excessive glue at both joints: sheath hub to sideport tube stopcock to sideport tube verify sideport tube is securely attached by gently pulling on both joints: sheath hub to sideport tube stopcock to sideport tube per ifu sideport aspiration - aspirate the sideport when withdrawing the catheter, probe, or dilator to remove fibrin deposits that may have accumulated in or on the tip of the sheath.Sideport infusion - infusion through the sideport and catheter should be done after all air is removed from the system.No further follow-up is required.Personnel notification / training was conducted to prevent the recurrence of this issue.Risk is acceptable and oscor will continue to monitor this event type.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.
