Additional information: kinked (1339).Investigation - evaluation: a review of the functional testing, complaint history, drawings, device history record, instructions for use (ifu), quality control, and visual inspection of the returned device was conducted during the investigation.Although requested, no additional event information has been received.One flexor raabe guiding sheath (kcfw-4.0-35-55-rb-raabe) was returned with a boston scientific catheter inserted through the check-flo.The hub of the boston scientific catheter was stamped ".014 / 135" on one side and "bsc 19662409 033" on the other.The length of the boston scientific catheter exiting the proximal fitting of the sheath was 91.0 cm.The dilator of the kcfw-4.0-35-55-rb-raabe was also present, but was not inserted through the sheath when returned.The boston scientific catheter was removed during examination and no damage was noted to the catheter.A kink is noted on dilator at 6.3 cm from the proximal end.The dilator was able to be fully inserted into the sheath.No damage is noted to the sheath.The device was flushed with and without the catheter and no leakage was detected.The distal end of the device was then occluded for a leak test, and when a 20cc syringe was used to inject down the side arm, fluid formed on top of the silicone disc.The check-flo cap was disassembled for further examination of the disc.The disc slit was present and centered.A document-based investigation was performed.There is no evidence to suggest the finished product was not made to specifications.Review of the device history record of the finished product shows no nonconforming events that could contribute to this failure mode.A complaint history search revealed that there were no other reported complaints for this lot number.Based on the information provided, examination of the returned product, and the results of our investigation, a definite root cause could not be determined.Per the [quality engineering] risk assessment, no further action is required.Monitoring will continue to be performed 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.A document-based investigation was performed.There is no evidence to suggest the finished product was not made to specifications.Review of the device history record of the finished product shows no nonconforming events that could contribute to this failure mode.A complaint history search revealed that there were no other reported complaints for this lot number.Based on the information provided, examination of the returned product, and the results of our investigation, a definite root cause could not be determined.Per the [quality engineering] risk assessment, no further action is required.Monitoring will continue to be performed 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.
