(b)(4).Device evaluation: the reported complaint of during insertion the sheath was damaged was confirmed.Returned was one peel-away sheath/dilator assembly in an opened kit.Visual examination revealed that the sheath assembly was damaged along both score lines.The dilator appeared used but typical; no damage was observed.Microscopic examination revealed that both sides of the sheath body are rippled at 2.0-3.2 cm from the tip.In addition, on one side of the body, proximal of the ripples, the sheath is torn open along the score line and the material is white and stretched.The opposite side of the sheath revealed that the material in the score line is stretched and white but was not opened.The sheath tip edge is pushed back multiple times creating an uneven edge.This damage is consistent with use.Manufacturing was consulted, and has stated that the damage observed and the observation of the white stress material in the deformed areas indicates that stress was applied to the sheath after the extrusion process and likely during use.Instructions for use describe suggested techniques for placement of the sheath and dilator assembly.A device history record review did not reveal any manufacturing related issues.Therefore, operational context caused or contributed to this issue.No further action will be taken.
