It was reported that resistance was met with the winn guidewire and the challenging anatomy.Approximately 3 mm of the guidewire tip broke during advancement with resistance to the heavily calcified, mildly tortuous, 100% stenosis lesion and chronic total occlusion (cto) in the right posterior tibial artery.The separated tip remains lodged in the cto lesion.There were no adverse patient sequelae.An ht command es guidewire was used to complete the procedure.No additional information was provided.

A visual and dimensional inspection was performed on the returned device.The reported material separation was confirmed.The reported failure to advance could not be tested as it was based on operational context.A review of the production records and the corrective and preventive actions (capa) database was performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed no indication of a lot specific issue.The investigation determined the reported difficulties and subsequent patient effects appear to be related to the operational context of the procedure.It was reported that the guide wire met resistance with the patient¿s heavily calcified, mildly tortuous, and 100% stenosed lesion during advancement, resulting in the reported failure to advance.Additionally, it was reported that the guide wire separated during advancement.Analysis of the returned wire confirmed the separation.The separated face was noted to be jagged, indicating manipulation at a kink or bend.The analysis also noted, stretched/ misaligned coils and a bent distal core.These types of damages are consistent with interaction with challenging anatomy.It is likely the wire sustained damage during advancement, contributing to the reported material separation.The separated portion remains embedded within the anatomy.There is no indication of a product quality issue with respect to manufacture, design, or labeling.Correction b2 outcomes: removed "required intervention".Replaced it with "other serious".
