Corrected data: b5 correct size used in procedure is 14fr x 25cm.The device was used in treatment.One 14f, 25 cm long abiomed introducer sheath was returned from the customer without the dilator.There were no other accessories.Blood was found on and inside the sheath and sideport tubing.Three kinks were observed on the sheath tube.Upon evaluation of the returned sheath under 10x magnification, there were three kinks observed in the sheath tube at approximately 7, 9 and 10cm from the distal tip.The distal tip of the sheath looked normal along its circumference edges.The hemostatic valve looked normal with its helical cuts intact.The sheath was measured with a pin gauge and was within manufacturing specifications.The impella device used in the procedure was not returned to oscor so a fit check could not be performed.The sheath (including the inner diameter) is within manufacturing specifications.Potential contributing factors to the kinks could be if the sheath was advanced through an area of resistance or if the sheath was subjected to unusual stresses.No manufacturing defects were found.The device history records were reviewed to confirm that the device passed all applicable in-process and final inspections.Per procedure abiomed introducer sheath in-process and final inspection: these steps are performed by qa as per sampling plan ansi z 1.4, gen level i, aql 0.65.Measure dimensions: b) measure tip i.D.Of sheath using appropriate pin gauges.Visual inspection: this step is performed by qa for sample size of 100% inspection a) with naked eye at a distance of 12" to 18", verify the assembled sheath matches the drawing.Ensure parts are free of kinks, cracks, splits, sinks, excessive flash, loose/embedded fm, or any other damages.The instructions for use (ifu) informs the user: never advance or withdraw guidewire or sheath when resistance is met.Determine cause by fluoroscopy and take remedial action.When injecting or aspirating through the sheath, use the sideport only.Avoid subjecting the device to unusual stresses.When assembling the sheath and dilator, care must be taken to insert the dilator tip straight through the center of the valve membrane in order to prevent inadvertent puncturing of the membrane.Based on the investigation, a capa is not required as findings did not identify a design, labeling or manufacturing non-conformity.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.
