(b)(4).The report of a leaking sheath was confirmed through complaint investigation of the returned sample.The customer provided one photo and returned one, sheath assembly for analysis.Signs of use in the form of biological material were observed on the sample.It was observed on the returned sample that a portion of the distal hub was connected to the sheath assembly.It appears that the distal hub had separated.The cath-gard sleeve and proximal hub were not returned.Inquiries to the customer have been made, and the issue will be investigated in another complaint.Visual analysis revealed three holes on the sheath body; two on the ribbed portion and one towards the center of the sheath body.The edges of the holes were smooth and appeared consistent with damage due to contact with a sharp instrument (i.E.Scalpel, scissors, etc).The location of the holes measured 10 mm, 12 mm, and 25 mm via calibrated ruler from the juncture hub.The sheath body length measured 4 3/16" via calibrated ruler from the juncture hub, which is not within the spec ification limits of 4"-4 1/4" per the sheath product drawing.However, the condition of the ribbed portion of the sheath body appears consistent with being stretched by undue force.The sheath body outer diameter measured 0.14720" via calibrated micrometer, which was within the specification limits of 0.147"-0.157" per the sheath product drawing.Functional inspection was performed per the instructions for use (ifu), "to check for proper sheath placement within the vessel, remove side port end cap and attach syringe for aspiration.Flush and connect side port to appropriate line as necessary." a lab inventory syringe filled with water was attached to the side port and flushed.Water leaked out of the holes on the sheath.The ifu provided with the kit informs the user, "do not secure, staple and/or suture directly to outside diameter of device body or extension lines to reduce risk of cutting or damaging the device or impeding device flow.Secure only at indicated stabilization locations." a device history record review based on a potential lot from sales history did not reveal any relevant findings.Based on the customer report that the damage was observed during use and the appearance of the damage, unintentional user error (contact with sharps) likely caused or contributed to this event.Telefl ex will continue to monitor and trend for reports of this nature.
