It was reported that the procedure was to treat a lesion located in the subclavian with mild tortuosity and mild calcification.With an unspecified 5fr sheath in place, a hi-torque (ht) versacore floppy 260cm guide wire was advanced via left radial access past the subclavian vessel without resistance.When advancing an unspecified 035 diagnostic heart catheter approximately halfway over the versacore, resistance was felt against the versacore, but no force was applied.The diagnostic catheter was retracted with no noted resistance.Upon withdrawal of the versacore, unraveling of the tip coil and a possible core separation were noted.During the same procedure, the exact same issue occurred with another same part and lot of versacore.The procedure was completed using a non-abbott guide wire without issue.There were no adverse patient effects and no occurrence of a clinically significant delay.No additional information was provided.
