Block h6: medical device problem code a15 captures the reportable event of clip unable to release from catheter.Block h10: investigation results: the returned resolution clip device was analyzed, and a visual evaluation noted that the device was returned without the clip assembly and the device had evidence of a full deployment.The device was returned without its outer-sheath.It was also observed that the bushing had evidence of flaring.Microscopic examination was performed and it was found that the bushing had hit marks and the bushing tabs were rounded.Dimensional analysis was performed on the bushing outer diameter, and it was found to be within specification.A dimensional analysis was also performed between the hooks of the bushing and the pin gage, and both were confirmed to be out of specification.No other problems with the device were noted.Based on the condition of the returned device, the reported event of clip unable to release from catheter was confirmed.Investigation found that the hooks of the bushing were out of specification and the capsule tabs were rounded with evidence of flaring of the capsule into the bushing which can be traced to the manufacturing process as a contributing factor and may have contributed to the clip deployment problem.Additionally, the hit marks found on the bushing is likely due to the flaring of the capsule onto the bushing.Therefore, the most probable root cause is manufacturing deficiency, as the reported event was traced to the manufacturing process.An investigation to address this problem is in progress.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.
