It was reported that "when flushing the device, the white plastic edge that allows the introduction of the swg and the catheters without arterial reflux, separates and fell off.Clinical consequences: as the introducer cannot be used, a second introducer of same lot was used without any incident.The medical staff reported that a similar incident happened a few days ago but the lot number was not recorded.".The issue was identified prior to use, there was no patient harm or consequence reported.

(b)(4).The customer complaint of a valve assembly separation was confirmed through complaint investigation of the returned sample.The customer returned one sheath/dilator assembly.The seal was returned separated from assembly and cap was returned assembled to the hemostasis valve body.The seal is intended to sit within the hemostasis valve body.No definite signs of use were observed.Visual analysis revealed minor damage to the hemostasis cap.The cap was removed to further investigate the components.After failing functional testing, the seal was further analysed, and it was identified that the seal slits were smaller than intended.The inner diameter of the hemostasis cap measured 0.3285" via calibrated caliper, which was within specifications of 0.315" - 0.325 per cap valve graphic.The diameter of the seal measured 0.3241" via calibrated caliper, which was within specifications of 0.315" - 0.325 per seal graphic.Further dimensional analysis was performed with a keyence microscope.Microscopic dimensional analysis revealed that the slits measured 0.0245", 0.0214", and 0.0244", which is not equal to the nominal value of 0.040" per the seal product drawing.The components were functionally tested per the instructions for use (ifu) provided with this kit, which instructs the user, "holding sheath in place, remove guidewire and dilator".The cap and seal were reassembled to the hemostasis valve body as intended.The dilator was inserted through the sheath.Slight resistance was encountered from inside the hemostasis valve; however, the dilator was able to fully advance and snap into the cap, which is the intended function.Upon removal of the dilator, it was observed that the seal was stuck to the dilator.This resulted in the seal to completely exit through the cap of the hemostasis valve.This likely occurred due to the seal slits being below the specification limits which resulted in resistance between the dilator and seal.The internal seal was inserted back over the dilator body.Minor resistance was encountered as the seal passes over the dilator extrusion.Manufacturing was contacted as part of this complaint investigation.Based on the dimensional analysis performed with the keyence microscope, the likely root cause is a supplier related defect.The ifu provided with the kit informs the user, "do not apply excessive force in removing guidewire or sheath/dilator.If withdrawal cannot be easily accomplished, determine cause using fluoroscopic guidance and request further consultation, if necessary".A device history record review was performed, and no relevant findings were identified.Based on the customer report, the sample received, and the comments from manufacturing, the root cause is likely supplier related.Further investigation has been initiated under teleflex's quality system by the manufacturing site to further investigate this issue.Teleflex will continue to monitor and trend on complaints of this nature.
