Qn# (b)(4).The customer returned one 9 fr.Dilator for evaluation.Visual inspection of the sample revealed a damaged dilator tip.The dilator tip looked split and frayed.This damage is consistent with undue force being applied during an attempted guide wire or dilator insertion.The dilator body total length form the end of the hub to the distal tip measured 8 1/4" which is within the specification of 8 1/32"- 8 9/32" per dilator product drawing.The dilator outer diameter measured 0.1185" which is within the specification of 0.117"-0.120" per product drawing.The dilator tip inner diameter could not be measured accurately due to the damage to the tip.A lab inventory guide wire with a diameter of.035" was inserted through the dilator.Little to no resistance was observed as the guide wire passed through the assembly.A device history record review was performed, and no relevant findings were identified.The instructions for use (ifu) provided with this kit warns the user, "warning: do not apply excessive force in removing guide wire, dilator or access device.If withdrawal cannot be easily accomplished, a chest x-ray should be obtained and further consultation requested." the report of a damaged dilator tip was confirmed through complaint investigation of the returned sample.Visual analysis revealed that the dilator tip was split.The appearance of the damage is consistent with undue force being applied during insertion.The dilator met all relevant dimensional and functional requirements, and a device history record review was performed with no relevant findings.Based on the customer report and the sample received, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
