Manufacturer Narrative
|
The surgical pattie was not returned for evaluation but a photo was provided: device history record (dhr): there is no indication that the production process may have contributed to this complaint.All test results passed procedural specifications.Failure analysis: the pattie/strip photo was inspected using the unaided eye.Complaint of burn around area of the green string was confirmed.The complaint could be verified through failure analysis.The cottonoid is formed from a rayon material.During processing, rayon material is broken down into small fibers.If the fibers are not properly broken down, a small cluster of fibers can result.This creates a thick spot in the pattie.When the string is ultrasonically welded on this spot it absorbs more energy than the rest of the pattie and results in a burn.Automated machines are used to produce 245411 patties.The patties are inspected by a computer vision inspection system that inspects the patties for defects.The burn marks are difficult to detect due to the type of color filters used on the camera lens.A corrective action was initiated to further investigate the failure.
