On (b)(6) 2017 the customer reported: "(b)(6) old female had first post-op clinic visit.During attempt to remove two jp drains, they snapped off and portion remained in patient.Patient scheduled to undergo surgery, the next day for removal.Patient underwent exploratory laparotomy and removal of retained drains under general anesthesia, no complications and patient discharged home.Per surgeon, drain was not caught in suture line and had not been damaged/melted by cautery.Stated, saw no marks or issues with drain when surgically removed them.Stated no known reason for the drain to snap.The portion that broke off in the clinic were not saved so only the portion in the patient that were surgically removed available to send to manufacturer." on (b)(4) 2017 we received two pieces of jp-2214 drains, only the white flat portions of them, broken off their shafts in the drain-shaft connection point.Investigation: the batch p1504640 was supplied to the customer in quantity of (b)(4) pieces on 04/07/2015.No non-conformities reported.No additional complaints received for similar failure.Batch history review of the batch p1504640 was performed.No non-conformities reported.The drains of this batch were sample tested for tensile strength (pulled until broke) in the connection area, exactly where the complained samples broke.The test results were ok: min.Result is 84.1n while the minimum requirement is 50 n.We inspected the retain sample from the batch p1504640.During the visual inspection, no cuts scratches or other damages detected.The sample was tested for tensile strength in the connection area with ok result: min.Result is 79.8 n while the minimum requirement is 50 n.(b)(4) samples from the current batch were tested for tensile strength in the connection area with ok result: min.Result is 77.6 n while the minimum requirement is 50 n.Conclusion: during internal investigation, we found no failures in our parts or processes.Silicone drains are known for their property to snap easily in area which was previously slightly damaged/cut/nicked.Probably, the drains were damaged in use and later snapped when pulled for removal.The complaint will be closed as not justified; no action is required in this case.
