The operator replaced the product with a new device, and no further issues were reported.
No anatomical abnormalities were noted at the access site.
The customer confirmed that no patient adverse events resulted from the product problem, and no additional procedures were necessitated.
The complaint device is reportedly unavailable for return and evaluation.

Investigation - evaluation: a review of the complaint history, device history record, documentation, drawing, manufacturing instructions, quality control, and specifications of the device was conducted during the investigation.
The complaint device was not returned; therefore, no physical examinations could be performed.
However, a document based investigation evaluation was performed.
There is no evidence to suggest the product was not made to specifications.
The appropriate manufacturing documents from the device master record (dmr) pertaining to the reported failure mode were reviewed, revealing no notable gaps in the manufacturing process.
Documentation indicates to confirm the distal tip of the dilator is rounded, smooth, free of excessive nicks and debris, and to reject the product if any splits are noted.
A review of the device history record shows no nonconforming events which could contribute to this failure mode.
It should be noted there were no other reported complaints for this lot number.
There is no evidence confirming this failure was manufacturing related or shipping/handling related.
Based on the information provided, no product returned and the results of our investigation, a definitive root cause could not be determined.
We will continue to monitor for similar complaints and have notified the proper personnel about this event.
Per the quality engineering risk assessment no further action is required.
