H.6.Investigation: the customer reported a leak in the tubing during priming, and returned one used sample of material #2420-0007 lot #21043386.The sample was clearly leaking from a cut or tear in the silicon near the lower fitment.The edges of the cut were quite jagged and looked to be done inadvertently by a machine sharp edge.The sample was investigated further by the manufacturing team, and they found the root cause to be possible incorrect material handling, edges in the fixtures, part caught in the machine during assembly, or improper method followed.This summer, a quality alert to the root causes was issued and a person was assigned to review the correct use of fixtures.A device history record review for model 2420-0007 lot number 21043386 was performed.There were no quality notifications issued for the failure mode reported by the customer during the production build of this set.A complaint history check was performed and this is the 1st related complaint reported with the defect/condition of leakage with lot #21043386 regarding item #2420-0007.
