Additional Manufacturer Narrative
(b)(4).The customer returned one unit of 528235 visistat 35w 6/box for investigation.Visual examination of the returned sample revealed that the staples appeared severely misaligned.The stapler was returned with 37 staples remaining in the cover block.The trigger was not returned engaged.No clear evidence of use in the form of biological material was present on the device.An attempt to fire staples was made by engaging the trigger of the stapler using hand pressure.Upon functional inspection, it appeared that the staple misalignment prevented the remaining staples from consistently firing correctly.In total, five staples were fired.All five staples did not form properly.The stapler was disassembled, and it was confirmed to have been assembled correctly.Die casting anomalies were observed on the forming tool.No other defects or anomalies were observed with the device.A device history record review was performed and no relevant findings were identified.The ifu for this product states, "to obtain optimum staple closure, the trigger must be squeezed all the way in." the reported complaint was confirmed based upon the sample received.Visual examination revealed that the staples appeared to be severely misaligned.Upon functional inspection, it appeared that the staple misalignment prevented the remaining staples from consistently firing correctly.The sample was disassembled, and die casting anomalies on the forming tool was discovered.No other defects or anomalies were observed.Each stapler is fired three times and then 100% inspected for proper staple alignment at the manufacturing site.For this reason, it is unlikely that the issue was present at the time of assembly.A dhr review was performed with no evidence to suggest a manufacturing related cause.It could not be conclusively determined what caused the staples to misalign.A non-conformance was opened by the manufacturing site to further investigate the issue of visistat 35w staplers failing to function properly.Teleflex will continue to monitor and trend on complaints of this nature.
