This follow up mdr is created to document the evaluation of the returned device.A touch pump, two cylinders and reservoir were received for evaluation.Examination and testing of the returned components revealed abrasion on the cylinder 2 exhaust tubing.Groups of striations, indicating contact with unshod instrumentation, were noted on the reservoir inlet tube and strain relief.Testing revealed these to not be sites of leakage.One of the pump exhaust tubes were detached to allow for testing.No functional abnormalities are noted with the pump, either cylinder or detached tubing.Because no functional abnormalities were noted with the returned components, other than instrument damage, the complaint cannot be confirmed as reported.Because these components were released according to manufacturing and quality control procedures, it was concluded that the observed instrument separations on the reservoir inlet tube and strain relief occurred subsequent to the device packaging being opened.In addition, because the expected use of this device combined with the observed separation would have resulted in an earlier detected fluid loss, it was concluded that the separations most likely occurred during or subsequent to explant.These separations are not associated with the cause for failure.
