This report is being submitted as follow up no.1 to update section h3, and to provide the completed investigation results.H6: investigation findings - 3211 is based upon evaluation of user facility information and the returned sample; 213 is based upon dimension testing of the returned sample.One used 8fr angio-seal evolution was received for product evaluation.The arteriotomy locator, hemostasis sheath and carrier tube assembly were returned for evaluation.No other accessory components were returned.Upon visual analysis, there were no anomalies with arteriotomy locator or the hemostasis sheath.Sheath hub was observed under the microscope and a piece of collagen was stuck in the hub.It was able to be removed with a pair of forceps.Upon examination of the carrier tube assembly, the deployment sleeve was in forward lock position with the color bands concealed.No anomalies with the locks on the device cap.The distal end of the carrier tube was subjected to microscopic analysis and the anchor and the collagen exited the carrier tube shaft.The distal end of the carrier tube had multiple kinks and the tamper tube was exposed at the tip.For dimension testing, the outer diameter of the carrier tube was measured to be 0.102'' and which was within the specification of 0.102" +/- 0.005.The measurement was within the specifications defined in the engineering drawings active at the time of manufacturing.Anchor and collagen were cut from the carrier tube assembly and then the carrier tube was inserted into the hemostasis sheath.No resistance was experienced, and the device cap locked with the sheath hub.Device was pulled back into rear lock position to lock and the color bands were exposed.No anomalies were observed with the components.Based on the evaluation of the device, the complaint can be confirmed for assembly difficulty experienced by the user.The kinks observed near the manufactured slit of the carrier tube assembly which likely occurred as a result of insertion technique, could be the cause of the assembly difficulty experienced by the user.The carrier tube was dimensionally tested, and functional testing was performed for the sheath and carrier tube assembly after separating the anchor and collagen, no anomalies were noted.The device was in a conforming state when released from terumo control.There is no indication that any manufacturing, design or quality system issues may have led to this event.Currently, no action is recommended since this risk evaluation is within the predetermined limits in the failure mode and effects analysis (fmea).
