It was reported to boston scientific corporation that two speedband superview super 7 devices were used during an esophageal varicose ligation procedure performed on (b)(6) 2019.According to the complainant, during the procedure, the bands were attempted to be deployed, but the bands would not release.Reportedly, the device was removed from the patient and it was noted that the suture was not installed on the ligator cap.A second speedband device was used; however, the device fail to deploy elastic bands as there was no suture attached on the ligator head.The procedure was completed with another speedband superview super 7 device.Additionally, there was no difficulty setting up the devices.There were no patient complications reported as a result of this event.The patient condition at the conclusion of the procedure was reported to be stable.

Manufacturer Narrative

Initial reporter facility name: (b)(6) problem code 2907 captures the reportable issue of suture detached.Investigation results: the ligator head and irrigation catheter were only returned for analysis.Other components were not returned with the device.A visual examination of the ligator head found six bands present which were moved out of their original positions with some bands were caught under the other bands.It was also noticed that the ligator teeth were bent.It was also possible to observe that the suture was attached to the ligator head and an additional knot was found on the suture loop, confirming the reported failure of suture detached.Based on the evaluation of the returned device, these failures are likely due to anatomical or procedural factors encountered during the procedure which limited the performance of the device.It is most likely that the ligator head teeth were damaged due to handling and manipulation of the device during the procedure.Once the ligator head teeth are damaged, the suture can be detached from its position on the ligator head and this condition could have impacted the bands deployment activity, moving bands without being deployed, and contributing to the reported issues.Also, the suture can tangle with the bands which can result in difficulty to rotate the handle and continued attempts to deploy the bands can result in suture breakage.This failure is likely due to factors or conditions related to procedure during the use of the device that could have affected its performance and its intended purpose.Therefore, the most probable root cause is adverse event related to procedure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.A labeling review was performed and from the information available, this device was used per the directions for use (dfu)/product label.
