As the reported defective device was not returned, angiodynamics is unable to perform a device evaluation.The reported complaint description of tre-sheath tip fractured and migrated in patient (burnt by fiber) cannot be confirmed due to no product being returned for evaluation.Without receiving product for evaluation, we are unable to definitively determine a root cause for this incident.The most likely issue is that the fiber was withdrawn into the sheath sometime during the procedure but there is also the possibility that only the black tip separated from the shaft which is a different issue.A review of the device history records was performed for the reported packaging and component lots for any deviations related to the reported defect of the complaint.The review confirms that the lots met all material, assembly, and performance specifications.The instructions for use, which is supplied to the end user with this catalog number, states: "prior to and during use, avoid damaging the fiber by striking, stressing, or excessive bending.Do not coil the fiber tighter than a diameter of 20cm.Clinical safety and effectiveness data is not available for other fiber tip designs and diameters.Prior to and during use, avoid bending the introducer sheath and dilator as this can cause kinks and damage".A review of the angiodynamics complaint system noted no adverse trends for this complaint type and product family.This type of complaint will continue to be monitored for trends.Reference (b)(4).
