Qn#(b)(4).The customer returned one peel-away sheath with dilator assembly for analysis.Signs of use were observed on the sheath and dilator.Visual analysis revealed that the distal end of the sheath tip was damaged.No other defects were observed with the dilator.The sheath length from the tabs to the distal tip measured approximately 2 13/16" , which is within the specification limits of 2 5/8"-2 7/8" per peel-away product drawing.The sheath outer diameter measured 0.099", which is within the specification limits of 0.097"-0.102" per peel-away extrusion product drawing.The sheath inner diameter at the distal tip could not be accurately measured due to the nature of the damage.The peel-away sheath and dilator were functionally tested per the product instructions for use (ifu).The ifu provided with this kit instructs the user , "ensure dilator is in position and locked to hub of sheath." the dilator was removed, reinserted back into the sheath, and locked into the sheath hub.The dilator was able to pass through the sheath tip with little to no resistance.Manufacturing was contacted as a part of this complaint investigation.They stated that based on the customer report that the patient had "tough" skin and there was difficulty navigating through the vessel wall , undue force likely caused or contributed to the reported event.A device history record review was performed, and no relevant findings were identified.The ifu provided with the kit informs the user, "do not use excessive force when introducing guidewire, peel-away sheath over tissue dilator, or tissue dilator as this can lead to venospasm, vessel perforation, bleeding , or component damage.If necessary, enlarge cutaneous puncture site with cutting edge of scalpel, positioned away from guidewire.Insert catheter through peel-away sheath to final indwelling position.Retract and/or gently flush while advancing catheter if resistance is met." the report of peel-away body damage was confirmed through complaint investigation of the returned sample.Visual analysis revealed that the sheath tip was damaged.Despite the damage, the sheath and the dilator met all relevant functional requirements.Information from the customer suggests the insertion site was "tough", of which the ifu informs the user, "if necessary, enlarge cutaneous puncture site with cutting edge of scalpel, positioned away from guidewire." based on the customer report that the patient had "tough" skin and there was difficulty navigating through the vessel wall, undue force likely caused or contributed to the reported event.Teleflex will continue to monitor and trend for reports of this nature.
