(b)(4).The lot was manufactured from december 12, 2014 ¿ december 17, 2014.One unit was received for evaluation.The unit was returned to the plant containing approximately 25 ml of fluid in its reservoir.Visual inspection noted a thin spot approximately 1.59 mm in size located on surface of the inflated reservoir.Microscopic examination of the thin spot indicated that it was not cut.A functional flow test was subsequently performed.During the functional test, the unit was manually inflated with solution and after fill the unit was allowed to flow until the solution in the reservoir was emptied.As a result, no signs of leak or rupture were found on the reservoir after the solution was emptied.Therefore, the integrity of the reservoir was not compromised and the functionality of the device was not impacted.The reported condition could not be verified.A batch review was conducted and there were no deviations found related to this reported condition during the manufacture of this lot.Should additional relevant information become available, a supplemental report will be submitted.
