Returned for evaluation was a 400 micron pvak fiber.A visual examination of the returned fiber confirmed the fiber was fractured as reported by the end user.The root cause of the fracture was determined to be user technique when removing the spiral wrap that secures/protects the fiber distal tip resulted in an excessive amount of force being applied to fiber which resulted in the break.Possibly the fiber was pinched with excessive force when removing the spiral wrap.The customer's reported complaint description is confirmed, there was damage to the fiber observed near the tip.Although the complaint was confirmed a definitive root cause for the fiber damage cannot be definitely determined.Handling damage is likely root cause.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.At the vendor facility, during the manufacturing process, fibers are repeatedly bent and coiled and there is a final visual inspection performed with a hene laser to check the entire fiber length for defects prior to shipment.During the packaging step, the fibers are inspected for damage.Labeling review: the directions for use which is supplied to the end user with the reported catalog number contains the following statement "prior to and during use, avoid damaging the fiber by striking, stressing or excessive bending.Do not coil the fiber tighter than a radius of 60mm".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).
