(b)(4).The report that a peel-away did not tear correctly was confirmed through complaint investigation of the returned sample.The customer returned one peel-away sheath for analysis.Signs-of-use in the form of biological material was observed.Visual analysis revealed that one of the tabs did not tear correctly.This resulted in the extru-sion to separate.Further analysis revealed that one side of the sheath was split completely separated down the entire extrusion.The sheath body length from the tabs to the distal tip measured 2 13/16" via calibrated ruler, which was within the specification limits of 2 5/8"-2 7/8" per the peel-away product drawing.The sheath outer diam-eter/inner diameter could not be accurately measured as the sheath was completely split.R & d confirmed that the failure for this com-plaint was consistent with an extrusion defect.The ifu provided with the kit informs the user, "do not use excessive force when introduc-ing guidewire, peel-away sheath over tissue dilator, or tissue dila-tor as this can lead to vessel perforation and bleeding, or component damage".A device history record review was performed, and five rele-vant findings were identified for which further investigations were initiated to address the issue of a peel-away tearing incorrectly.Based on the customer report, the sample received, and the comments from r & d, manufacturing caused or contributed to this event.Further investigation has been initiated under teleflex's quality system by the manufacturing site to further investigate this complaint issue.Teleflex will continue to monitor and trend for reports of this nature.
