(b)(6).The lot 19e007 was manufactured between may 2-6, 2019.The device was received for evaluation.A visual inspection was performed, and it was noted that white striated marks resembling "crystals" were observed on the exterior surface of the bladder.The white striated marks were determined to be blooming antioxidant/ethanox which is a raw material/component of the bladder and not particulate or foreign matter.The purpose of antioxidant/ethanox is to prevent degradation of the bladder material.Blooming antioxidant/ethanox is a cosmetic condition and does not affect the functionality nor safety of the product.An ftir spectroscopy test was performed on the white striated marks and confirmed them to be ethanox/antioxidant.Functional testing was also performed, with no issues noted.The reported condition was not 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.
