Block d4, h4: the complainant was unable to report the lot number; therefore, the manufacture date and expiration date are unknown.Block e1: it was reported that the health care facility involved was columbus regional health care system.Block h6: imdrf device code a1409 captures the reportable event of peg tube obstructed.Block h10: the returned endovive safety peg kit push method was analyzed.Visual inspection noted that there were no problems with the device exterior.A functional test was performed using a 0.035 inch guidewire that was inserted through the entrance of the feeding tube.However, difficulty advancing the guidewire was noted and the guidewire could not pass through the transition joint/barb connector.The barb connector was isolated by cutting the sides of the tubing that it was connecting.Visual inspection of inside the barb connector showed obstruction on the side usually connected to the feeding tube in the form of glue/adhesive.No additional problems with the device were noted.With all the available information, although no complaint was reported, boston scientific corporation (bsc) determined that the peg tube obstruction was likely caused by adhesive inside the hypo-tube of the transition joint.Adhesive is used during assembly, and it is likely that the obstruction was the result of incorrect placement or excessive use of adhesive, resulting in obstruction of the hypo tube.Therefore, the most probable root cause is manufacturing deficiency.Bsc initiated a corrective and preventive action (capa) investigation to determine the root cause of this problem.The hypo-tube inside the transition joint of the returned device was found to be blocked with adhesive.Investigation identified a potential scenario in which the tip of the glue dispenser touches the threaded tip of the barb as it moves into position for glue and torque at the mini bolster.This could cause glue to migrate into the lumen of the barb component and cause a blockage.An initial containment was implemented on (b)(6) 2023, and the pneumatic flow valve of the equipment was adjusted to ensure that the glue dispenser does not move into position until the barb is in the correct position, preventing the potential for this issue to reoccur.Additional corrections were implemented on (b)(6) 2024 to add 100% pin gage inspection after the mini bolster step for push method device types.An investigation to address this problem has been completed.
