A technical director reported an issue with a pvak -- 400 micron perforator and accessory vein ablation kit.During preparation, the fiber was connected to the laser unit and light was seen coming from the middle of the fiber, indicating a fracture.When the end user touched the fiber, it "broke completely." the procedure was completed with another same device and the patient did not experience any adverse effects, harm, or require medical intervention as a result of this incident.

Returned for evaluation was an evlt pvak fiber.A visual inspection noted that the fiber fracture it was located at 70.2 mm from the distal edge of the black strain relief of the gripper.During the sme evaluation, it was noted: the fiber break occurred 70.2cm from the distal end of the black strain relief, the fiber glass core at the break point is jagged and the buffer on each side of the break is distorted, there is no sign of damage to the fiber buffer layer beyond the break point and the rfid tag indicates the number of uses a"0", therefore the laser was not fired before the break was observed.The customer's reported complaint description of the fiber was fractured and detached was confirmed based on evaluation of the returned sample.Although confirmed, a definitive root cause for the fiber fracture could not be determined.Handling damage is likely root cause for the fiber fracture/detachment, however, when is occurred could not be determined.A device history records search for the indicated packaging/assembly lots revealed no quality related issues or manufacturing deficiencies at the time of manufacture.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.Labeling review: the directions for use which is supplied to the end user with this 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).
