This follow-up mdr is created to document the evaluation of the returned device.A pump and two cylinders were received for evaluation.Examination and testing of the returned components revealed a separation in the longer exhaust tube of the pump.Testing revealed this to be a site of leakage.Abrasion is noted surrounding this separation.Partial separations, within abrasion are noted on all tubes of the pump.Testing revealed these to not be sites of leakage.A group of striations, indicating contact with unshod instrumentation, is noted on the exhaust tube of cylinder 2.Testing revealed this to be a site of leakage.Abrasion is noted on the exhaust tubes of both cylinders.No functional abnormalities were noted with cylinder 1.Based on examination of the returned product, the abrasion marks noted on all pump tubing matched in such a way to conclude that they had overlapped and abraded against one another while in-vivo, resulting in the separation noted on the longer exhaust tube.A separation of this type would then allow the loss of fluid, making the device inoperable.Because these components were released according to manufacturing and quality control procedures, the observed instrument separation in the exhaust tube of cylinder 2 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, quality concluded that the separation most likely occurred during or subsequent to explant.This separation is not associated with the cause for failure.
