Block h6: medical device problem code a15 captures the reportable event of clip was unable to release from catheter.Block h10: investigation results: the returned resolution 360 clip device was analyzed, and a visual evaluation noted that the clip assembly was not returned and the device had evidence of a full deployment.Microscope examination was performed, and it was observed that the bushing had hit marks on the bushing surface, indicating the interaction between the yoke and the capsule in order to make the deployment of the clip.Dimensional analysis was performed on the bushing outer diameter, and it was within specification.A dimensional analysis was performed between the hooks of the bushing, and both sides a and b were within specification.The bushing tabs measurement were symmetric and the flattening wire was confirmed to be within specification.Further dimensional analysis was performed on the braided shaft, and the lengths of various parts were within specification.No other problems with the device were noted.The reported event was not confirmed.The device returned without the clip assembly and it is important to mention that the presence of this component is very important to the investigation in order to analyze any failure that could contribute with the problem faced by the physician.The returned device review showed no evidence of either the alleged(s) or any defect which could have contributed to the event.Therefore, the most probable root cause for this complaint is no problem detected.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.
