Blank fields on this form indicate the information is unchanged, unknown or unavailable.Investigation - evaluation.A review of the complaint history, device history record, drawing, instructions for use, and quality control of the device was conducted during the investigation.The complaint device was not returned; therefore, no physical examinations could be performed.The investigation for a complaint (b)(4) that was received for a similar device experiencing the same failure mode was revisited.The physical examination of the device confirmed that the white hub was cracked, starting at the proximal end.No tool markings were noted on the hub.It was concluded that the creation of the crack was possibly related to the increased torque applied to the hub, but a definitive cause could not be concluded.Because of the similarities between the referenced and current complaint, it is possible that the two have the same cause.There is no evidence to suggest the complaint device was not manufactured within the correct specifications and tolerances.Additionally, a document-based investigation evaluation was performed.It was concluded that sufficient inspection activities are in place to identify this failure mode prior to distribution.Risk specification lists leakage/separation of the catheter hub as a potential failure mode.The analysis indicated that the correct risk controls are in place for this failure mode, and the risks associated with these devices are acceptable when weighed against the benefits.A review of the device history record showed no nonconformances for lot 9294271 or catheter subassembly lot ic9097355.It should be noted that there have been no other complaints reported for the device lot.It was concluded that there is no evidence that nonconforming product exists in house or in the field.The instructions for use (ifu), provides the following information to the user related to the reported failure mode: power injection procedure: "4.Ensure adequate blood return and flush catheter vigorously with the entire 10 ml of sterile normal saline to ensure lumen patency.Warning: failure to ensure patency of the catheter lumen prior to injection may result in catheter failure.5.Remove syringe and attach power injection device to the catheter using the manufacturer's recommendations.6.Conduct study using the power injector, making sure not to exceed the maximum flow rate or pressure limit for the catheter." how supplied: "upon removal from package, inspect the product to ensure no damage has occurred." based on the information provided, no returned product and the results of our investigation, a definitive root cause could not be established.The device was in place for ten days prior to failing, suggesting there was no device failure during placement.This further suggests that the failure mode was possibly related to catheter maintenance.It is also possible that the crack in the hub was caused due to excessive outside forces.If too much torque was applied to the hub during device maintenance, it could have caused the hub to crack.Per the quality engineering risk assessment, no further action is required.The appropriate personnel have been notified and we will continue to monitor for similar complaints.This report is required by the fda under 21 cfr part 803 and is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement contained herein is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, nor that any cook device caused, contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
