(b)(4) the customer returned one psi sheath for analysis.Signs of use in the form of biological material were observed on and within the device.Visual analysis revealed that the sheath sidearm was completely separated from the hemostasis valve body.Indentations were visible on the sidearm extrusion at the point of separation.The sheath sidearm outer diameter measured 0.2085", which is within the specification limits of 0.208"-0.212" per the sidearm extrusion graphic.The sheath sidearm inner diameter at the hub end measured 0.129", which is within the specification limits of 0.128"-0.132" per the sidearm extrusion graphic.The smaller and larger outer diameter of the hemostasis valve body at the connection site with the sidearm were measured.The larger outer diameter measured 0.1955", which is not within the specification limits of 0.198"-0.202".The smaller outer diameter measured 0.1545", which is within the specification limits of 0.1540"-0.159" per the hemostasis valve body drawing.Manufacturing was contacted as a part this complaint investigation.They confirmed the defect is due to a known manufacturing issue and a change was implemented on 22-july-2024 to increase the tooling dimensions on the hemostasis valve body connection site to improve the connection with the sidearm.The sheath involved with this complaint was manufactured 06-july-2024, which is prior to this implementation date.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 placing or removing guidewire, dilator, or sheath.Excessive force can cause component damage or breakage." the customer report of a sheath sidearm separation was confirmed through complaint investigation of the returned sample.The hemostasis valve body, which connects to the sidearm, failed dimensional testing.The connection site for the sidearm to the body was undersized which could have contributed to the separation of the sidearm.Based on these circumstances, manufacturing likely caused or contributed to this event.A non-conformance was initiated to further investigate this issue.Teleflex will continue to monitor and trend on reports of this nature.
