(b)(4).The customer provided two images for analysis.The images reveal the separated sheath body and lidstock details.The customer also returned one sheath and product lidstock for analysis.Definite signs of use in the form of biomaterial were observed on the sheath.Visual analysis revealed that the sheath extrusion was separated from the hemostasis valve directly adjacent to the juncture hub.The hemostasis valve body was also observed to be slightly cracked/chipped.Microscopic examination of the point of separation revealed that the sheath extrusion was slightly stretched.The overall length of the sheath extrusion measured 26", which is within the specification limits of 25" - 26" per the sheath/dilator assembly drawing.The outer diameter of the sheath body measured 0.1265", which is within the specification limits of 0.124" - 0.128" per the wrapped sheath extrusion graphic.Functional inspection could not be performed due to the separation of the returned device.The manufacturing facility was previously contacted regarding defects of this nature.They indicated that based on the appearance of the point of separation, the sheath was properly attached to the hub.They also indicated that the damage appears consistent with undue force being applied during use.A device history record review was performed and no relevant findings were identified.The instructions for use (ifu) provided with this 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." the customer report of a sheath body separation was confirmed through investigation of the returned sample.Visual analysis revealed that the sheath body had become separated directly adjacent to the connection point at the juncture hub.The components passed all relevant dimensional requirements.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 the manufacturing facility, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
