Qn#(b)(4).The customer returned one 2-lumen picc and peel-away sheath for evaluation.Visual examination of the sheath revealed slight damage adjacent to the hub.The damage appeared consistent with forceps holding the sheath body.Visual examination of the catheter did not reveal any defects or anomalies.The outer diameter of the returned catheter measured to be 0.074" which is within specifications of 0.069-0.074" per product drawing.The inner diameter of the proximal end of the returned sheath measured to be 0.083" which is greater than the minimum specifications of 0.079" per product drawing.The inner diameter of the distal tip of the returned sheath measured to be 0.077" which is within specifications of 0.077-0.078" per product drawing.The returned sample was functionally tested in accordance with the instructions-for-use (ifu) provided with this kit.The ifu instructs the user, "insert catheter through peel-away sheath to final indwelling position.Retract and/or gently flush while advancing catheter if resistance is met." the returned catheter was advanced through the returned sheath with minimal resistance.The catheter and sheath were also dimensionally and functionally tested.Several catheter outer diameter measurements were taken using a laser micrometer and the maximum outer diameters were all in a range that would fit through the sheath tip inner diameter.Additionally, functional testing confirmed that minimal resistance was met when advancing the catheter through the sheath.A device history record review was performed with no relevant findings.The customer report of catheter/sheath resistance could not be confirmed by complaint investigation of the returned sample.The catheter and sheath passed all relevant dimensional and functionally testing, and a device history record review was performed with no relevant findings.No problem was found with the returned sample.Teleflex will continue to monitor and trend for complaints of this nature.
