Manufacturer Narrative

Product was returned to johnson & johnson for failure analysis, and the following was performed on the returned unit: the perforator unit was visually inspected and no anomalies were observed other than slight wear to the product label.Ifu testing was performed with no observed anomalies.Testing included: · applying adequate pressure on the perforator point, ensuring engagement occurs as the hudson end is rotated.· when engagement occurs, placing thumb pressure on the perforator point to ensure a smooth, positive spring action.· ensuring the hudson end rotates smoothly within the perforator body when the unit is in the disengaged position.Functional testing was performed using the same protocol the unit underwent at finished goods testing prior to release.The unit was found to perform as intended, and passed acceptance criteria, which includes evaluation of the disengagement feature and any erratic or poor cutting action.In the failure analysis performed, the returned unit was found to meet all acceptance criteria.The failure analysis report is attached as supporting documentation.The complaint could not be verified through failure analysis.
