It was reported that a blood leak was occurred at the luer lock connector of hls cannulae.The failure was occurred on after 4 days of insert.Customer stopped using the product after the leakage.No harm or death to any person was reported.The sample was discarded by customer and therefore laboratory investigation could not be performed.Further, a photograph could not be provided by customer.The reported failure was occurred during treatment, and product change was required, based on this failure could be confirmed.The production history record (dhr) of the affected be-pal 1723 with lot# 3000341443 was reviewed on 2024-02-15.According to the dhr results, the product be-pal 1723 passed the defined manufacturing and final release specifications.Thus, production related influences are unlikely.Further, the incoming inspection report (batch # 3000276586) of the affected component "700000285 / 00285#konnektor 3/8 x 3/8 ll" was reviewed on 2024-03-04.The connector were checked for damages, scratches, marks, rills, sinks, streaks, and cords visually.Visual tests were passed as per specifications.Due to this, material related influences are unlikely.Based on the investigation results, the exact cause of the reported failure could not be determined.However, the reported failure could be linked to the risk assessment and control of hls cannulae (dms #3186956, v01) and the probable causes are associated to: manufacturing: - use of wrong or out-of-spec materials user error - lack of attention during device handling: - unintended removal of fem cap from cannula - mechanical damage of cannula connection during removal of fem cap - dearing of cannula (tightening luer cap) - damage of cannula connection during connection of tube line - mechanical damage of cannula during fixation - disconnection of drainage cannula from tubing line these root causes could not be confirmed.The customer will be informed about the investigation results by sales and service unit.The occurrence rate was calculated for the reported failure and product and it was determined that this is not a systemic issue.Therefore, no remedial action is required.The occurrence rate related to the reported issue is currently being monitored as part of maquet cardiopulmonary¿s trending program and additional investigations or corrections will be implemented in case of adverse trending.
