Manufacturing review: device history record (dhr) for lot number vtan0268 was reviewed and the lot met all release criteria.The dhr review showed that all process parameters were within specification and that this lot of grafts passed all physical testing requirements.No changes have been made to the manufacturing process that would impact this complaint.Visual/microscopic inspection: as the device was not returned, an inspection could not be performed.Functional/performance evaluation: as the device was not returned, an evaluation could not be performed.Medical records review: as medical records were not provided, a review could not be performed.Image/photo review: as medical images were not provided, a review could not be performed.Conclusion: images and medical records were not provided.The investigation was inconclusive for the alleged graft tears.The definitive root cause could not be determined based upon available information.It was unknown whether patient and/or procedural issues contributed to the event.Labeling review: the current ifu (instructions for use) states: warnings: do not remove the external spiral support (beading) from any centerflex¿ graft or endflex¿ graft.Attempts to remove the beading may damage the graft wall.If damage occurs, discard the graft.Precautions: when removing the external spiral support (beading) of impra flex¿ grafts, the beading must be removed slowly and at a 90° angle to the graft.Rapid unwinding and/or removal at less than a 90° angle may result in graft damage.Do not use surgical blades or sharp, pointed instruments to remove the beading as this may damage the graft wall.If damage occurs, that segment of the graft should not be used.The information provided by bard represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bard.
