After opening the nevertouch laser fiber kit, they proceeded to remove the white peel-away spacer mounted on the fiber that lets the user know when the laser fiber tip is equal to the sheath tip.The physician used a scalpel to help remove the piece (spacer), inserted fiber into the patient, and after they activated the laser, they noted red light emanating close to where the laser fiber connected to the tre-sheath.They stopped treatment, opened another fiber kit and replaced the laser fiber and completed the case.The initial sheath was left in place so the new (second) fiber could be introduced.The end user did not notice any describable damage to the product (fiber), with exception, the fiber turned red up by the sheath hub and it never did that before.The patient did not experience any adverse effects, harm, or require medical intervention because of this incident.

Returned for evaluation was a fiber which was noted to be in 2 pieces and a fiber stop.The customer's reported complaint description of the fiber fractured and detached is confirmed.The root cause for the fiber fracture was due to handling damage by the end user.The end user had an issue with removing the fiber stop and used a scalpel to cut the tubing in order to remove the fiber stop.The returned fiber sample shows marking/scrapes which were caused by using a sharp instrument which caused damage to the fiber.The customer's reported complaint description of unable to remove the fiber stop tubing was confirmed since the review of the fiber stop showed that there was no slit in the tubing (tubing is slit to aid end user in removing it from the fiber).The root cause for the tubing not being slit was due to a manufacturing non-conformance.As a correction, a manufacturing awareness training was performed for the individuals responsible for fiber stop tubing slitting for the fiber assembly lots in question (5753570 and 5752218).A device history records search revealed no quality related issues or manufacturing deficiencies at the time of manufacture.During the manufacturing process and prior to packaging the fiber stop tubing is receives inspections from both manufacturing and quality to verify the presence of the slits.A review of the device history records was performed for the indicated lots for any deviations related to the reported failure mode of the complaint. the review confirms that the lots met all material, assembly and performance specifications; i.E.No ncr associated with reported failure mode.Labeling review: the instructions for use, which is supplied to the end user with this catalog number, states: "insert the nevertouch laser fiber into the sheath until the fiber stop assembly comes in contact with the proximal end of the sheath hub.Remove fiber stop assembly.Pull the sheath back and lock it to the sheath-lok fitting".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).
