(b)(4), complaint verification testing could not be performed as no sample was returned for analysis.The ifu provided with the kit informs the user "withdraw peel-away sheath over catheter until sheath hub and connected portion of sheath is free from venipuncture site.Grasp tabs of peel-away sheath and pull away from the catheter, while withdrawing from vessel until sheath splits down its entire length.Precaution: avoid tearing sheath at insertion site which opens surrounding tissue creating a gap between catheter and dermis".A review of dhr revealed findings for which it was not possible to assess the relevance without the device sample to evaluate.Without the device to evaluate, the complaint could not be confirmed, and the probable cause could not be determined from the available information.Teleflex will continue to monitor and trend for reports of this nature.
