(b)(4).The customer returned one dilator/sheath assembly for evaluation.The device did not appear to be used or damaged, therefore it was assumed a representative sample was provided.Visual examination of the dilator/sheath did not reveal any defects or anomalies.The sheath tabs were fully secured to the sheath extrusion.The total length of the peel-away sheath body measured to be 2.80" which is within specifications of 2.625- 2.875" per product drawing.The inner diameter of the sheath tip measured to be 0.064" which is within specifications of 0.064-0.065" per product drawing.The outer diameter of the sheath body measured to be 0.084" which is within specifications of 0.076-0.086" per product drawing.This indicates that the wall thickness measured within specifications.The returned dilator advanced and retracted from the returned sheath with minimal resistance.A manual tug test confirmed the sheath tabs were fully secured to the sheath body.A device history record review was performed with one potentially relevant finding.A non-conformance was initiated for incorrect sheath peeling.However, the sample returned contained no anomalies so this finding could not be confirmed to be relevant.The instructions-for-use provided with this kit instructs the user, "grasping near skin, advance sheath/dilator assembly with slight twisting motion to a depth sufficient to enter vessel.Note: a slight twisting motion may help sheath advancement.".The customer report of separated sheath tabs could not be confirmed by complaint investigation of the returned sample.The returned representative sample passed all relevant visual, dimensional, and functional testing.A device history record review was performed with no confirmed relevant findings.Without the actual sample to evaluate, this complaint could not be confirmed and probable cause could not be determined.Teleflex will continue to monitor and trend for complaints of this nature.
