Investigation: a device history review was conducted for lot number 8305840.Our records show that this is the third instance of this issue occurring in this production batch.According to the sampling plan applied for product performance, this lot was accepted and released without defects being noted during the final assembly or visual inspections.Our investigators noted a small crack was found during leakage testing that was located on the adapter.The returned product's swage dimensions were measured by our team and found to be within product specifications.However according to previous investigations, through a variance in the autoline's swage pressure it is possible for the machine to apply excess force to the device during assembly, allowing for the resulting crack to form in the device.Currently, we are conducting a long term study, capa#642738, to determine the root cause for this event, but we are addressing the issue through the implementation of manual inspections for cracks in the adapter head, and we are further optimizing our swaging process by reducing depth requirements.
