(b)(4).The results of the investigation are incomplete at the time of this report.
|
|
Event Description
|
The customer alleges that the wire unraveled becoming too weak to thread the sheath and causing a sharp end that bent sideways during removal.No patient injury or consequence reported.The patient's condition is reported as fine.

Manufacturer Narrative

(b)(4).Complaint verification testing could not be performed as no sample was returned for analysis.The device history records (dhr) for the guide wire were reviewed with no evidence to suggest a manufacturing related cause.The potential cause of guide wire unraveling could not be determined based upon the information provided and without a sample.If the sample is returned, a follow-up report will be submitted with investigation results.

Manufacturer Narrative

(b)(4).The customer returned one guide wire for evaluation.A visual exam was performed and it was observed that the guide wire had five kinks and was unraveled from the distal end.The distal weld was present at the end of the coil wire.Microscopic examination revealed that both welds were full and spherical and that the proximal weld appears intact.Microscopic examination also revealed discoloration and necking of the core wire in the area of the break.Discoloration at the broken end of the core wire was consistent with proximity to a weld.The broken core wire measured 600mm, which meets the length specification.The diameter was also found to be within specification.A manual tug test confirmed that the distal weld remains intact.A device history record (dhr) review was performed on the guide wire , introducer needle , and ars with no relevant findings.The instructions for use (ifu) for this product, describes suggested techniques to minimize the likelihood of guide wire damage during use.(con't) other remarks: the reported complaint of the guide wire unraveled was confirmed through visual inspection of the returned sample.The guide wire exhibited signs of use and was unraveled from the distal weld.No manufacturing defects were found during this investigation.Arrow guide wires of this size (0.32") are designed and manufactured to withstand a tensile force of 2.75 pounds force.This internal specification is higher than the bs en iso 11070:1999 standard of 2.2 pounds force for this size wire.The selected insertion site and patient anatomy may present a tortuous path that could contribute to the possibility of the guide wire kinking.Guide wire breakage may occur if a force greater than the design specification is applied during removal.Based on these circumstances, it was determined that operational context caused or contributed to the event.
