The following sections were updated in follow-up 1.One 23f abiomed introducer sheath was returned from the customer without the dilator.There were no other accessories.Blood was found on and inside the sheath.Upon evaluation of the returned product, it was found that the sheath tube was split in two places.The sheath was split on the score line in two places; one was located approximately 3.0mm from the distal tip and the other was split approximately 2mm from the distal tip.The tip has damage around the outer circumference.Blood residue was found on the sheath.The device history records were reviewed to confirm that the device passed all applicable in-process and final inspections.Returned device analysis revealed the sheath was within manufacturing specifications.Potential contributing factors to the damage (splits in tip) could be if the sheath was advanced through an area of resistance or if the sheath was subjected to unusual stresses such as tortuous patient anatomy.Another possibility is that the sheath was bumped or dropped prior to use.According to the device history record, the introducer sheath passed all in-process and qa final inspection steps before shipping to the customer including visual, dimensional and leak testing.No manufacturing defects were found.Per procedure (abiomed introducer sheath in-process and final inspections): measure tip i.D.Of sheath using appropriate pin gauges.Visual inspection: using 10x magnification, verify the tip is round, no flash protruding, and no flash with width (around circumference), no splitting, cracks or other damages.Per visual inspection, 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.Per ifu 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.Abiomed provides the ifu for this product.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.
