Received one 14f x 28cm split stream catheter for evaluation.A visual inspection reveals the catheter to be in 3 pieces.A small hole in the arterial lumen at the point where the lumens are bonded together was noted.A review of the manufacturing records was not possible as the lot number was not provided.The split stream catheter is manufactured by bonding two lumens together allowing the distal portion of the lumens to be separated by the physician as deemed appropriate.The proximal portion of the lumen is permanently bonded.Based on the sample review, the hole appears to be caused by stress in the transition area from "d" to "o".(this is the area where the shape of the lumens changes to create a flat surface that can be bonded together).Stress at this area can be caused by the operator manipulating the device during site care and during the dialysis treatment.The report indicated the catheter was implanted for 1.5 years with no reported problems.There is no evidence of swelling, crumbling, discoloration, degradation or polymer variation of the lumen and extension material.We are unable to determine the cause or factors that may have contributed to this event.There is no evidence of a manufacturing problem.
