An investigation of the reported condition was performed.The device history record (dhr) for lot indicates zero issues were found.A review of maintenance records (both corrective and preventive) and calibration records were reviewed and there were no issues found.All scheduled maintenance and calibration activities were completed on time.The exact root cause of the reported condition could not be determined without an actual sample to examine.If the material was tearing apart too easily it would most likely be an issue of the raw material construction.There have also been reports of the sponges being unfolded prior to use by the end user.The sponges are intended to be used in their folded state so it if they are unfolded prior to use it would contribute to the material coming apart.Prior to a lot¿s release, the lot must be deemed acceptable by passing inspections that are based on a valid sampling plan.Inspectors routinely examine a statistical sample both physically and visually.Specifically, samples are inspected from the beginning, middle, and end of each lot for bad weave.The lot met all defined acceptance requirements and was released.No complaint trend exists and the issue could not be confirmed, therefore, no corrective action is required at this time.This information will be utilized for trending purposes to determine the need for corrective actions.If information is provided in the future, a supplemental report will be issued.
