Qn#(b)(4).The report of a damaged smart seal sheath valve was confirmed through examination of the returned sample.The customer returned one, opened chronic hemodialysis kit for analysis.The peel-away sheath component will be analysed as part of this complaint investigation.Signs-of-use were observed on the sheath body.Visual analysis revealed that the sheath valve was damaged/defective.One side of the valve had separated from the hub and was lodged inside the housing.The sheath tabs were still completely connected; however, the perforated edge of the seal does not appear to align with the intended split location.Further microscopic examination revealed that the edges of the seal were smooth and uniform.The sheath tabs were intentionally split to better analyse the defective seal.Other than the separation, no obvious defects or anomalies were noted with the seal or the inside of the hub.The tabs of the sheath were intentionally split to better analyse the defective seal.It was noted that the hubs split as intended.R & d unit confirmed that the perforated line through the smartseal should run through the center of the circular opening of the tabs.This defect could restrict the passage of a catheter.Therefore, this is likely a supplier quality issue.The ifu provided with the kit informs the user, "introduce catheter through hemostasis valve/sheath and advance to desired position".A device history record review was performed, and no relevant findings were identified.Based on the condition of the sheath, the customer report, and the comments from r & d, the probable cause is supplier related since the component is purchased.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.
