Investigation/evaluation: a review of documentation including the complaint history, device history record, drawing, instructions for use (ifu), manufacturing instructions, quality control and specifications, as well as a visual inspection, dimensional verification and functional test of the returned device was conducted during the investigation.One catheter was returned for evaluation.Slight biological matter was observed throughout the device; however, no surface damage was noted.A tug and twist test of the tubing confirmed that the flare was secured within the cap.A leak test confirmed the presence of a leak at the cap-to-tubing interface.All dimensions deemed relevant to the failure mode were analyzed and found that the device was manufactured within specification.Additionally, a document-based investigation evaluation was performed.The proper procedures are in place to identify and prevent this failure mode prior to device distribution.The risk specifications covering mac-loc drainage catheters include both hub separation and leakage as a potential failure mode.The identified risk controls include manufacturing quality control checks and process validation.The technical files covering mac-loc drainage catheters indicate that the risks associated with these devices are acceptable when weighed against the benefits.A review of the device history record found one relevant nonconformance for the complaint lot for an inadequate flare, in which one device was scrapped.Although this nonconformance is relevant to the reported failure mode, the reported product goes through a 100% inspection for the reported nonconformance, and all nonconforming product was scrapped.It should be noted that there were no other complaints reported for this lot number.There is no evidence to suggest 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: how supplied: "upon removal from package, inspect the product to ensure no damage has occurred." based on the information provided, examination of the returned product and the results of our investigation, a definitive root cause could not be established.Appropriate measures have been taken to address this failure mode.The appropriate personnel have been notified.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.
