As reported, the 2mm x 10cm 155cm saber rapid exchange (rx) was attempted to be removed from the patient after it inflated the lesion, however, there was a stronger resistance felt between the non-cordis sheath and the saber device.The physician kept withdrawing but it got separated at the part where 4 cm before the 40 cm exit port at the distal end.The part(s) remained in the patient were on the non-cordis guidewire, therefore, they were attempted to be removed.The doctor cut near the tip of the kink.The non-cordis guidewire was withdrawn a little and the part(s) remained in the patient were withdrawn together.The physician kept withdrawing it and they were removed from the patient.There has been no reported patient injury after the procedure.There were no abnormalities on the saber device prior to using on the procedure.This was an endovascular therapy (evt) case.The lesion was the lower limb artery.An ipsilateral antegrade approach was made with a 4fr 10cm non-cordis sheath.A non-cordis guidewire crossed the lesion.It was mentioned that since a z-shaped kink was found on the non-cordis guidewire, which was outside the patient¿s body from the reverse blood valve of the sheath, it was difficult to insert other devices.The separated fragment(s) will probably be returned together.The non-cordis sheath, non-cordis guidewire and the saber device will be returned for analysis.The device was stored, handled and prepped per the instructions for use (ifu).The device was prepped normally by maintaining negative pressure.There was no difficulty removing the product from the hoop or removing the protective balloon cover.There was no difficulty removing the stylet or any of the sterile packaging components.The device did not kink or bend at any time prior to the resistance/friction.There were no kinks/bends noted after the resistance/friction was experienced.There was difficulty tracking through the vasculature.The same indeflator was used successfully with other devices.There were no kinks or other damages noted prior to inserting the product into the patient.The target lesion was the lower leg artery with little calcification.There was moderate vessel tortuosity/angulation.The device will be returned for analysis.

in-patient¿ and ¿pta/ptca system withdrawal difficulty - through guide/sheath¿ was confirmed by device analysis due to the severely damaged body/shaft and separated condition of the unit received.The body/shaft presented evidence of elongations at the separated area during analysis of the device.However, the exact cause of the damages noted cannot be determined.The elongations found on the body/shaft of the unit are commonly associated with separations caused by material tensile overload.These elongations suggest that the separated area was induced to stretching/pulling events that exceeded the material yield strength prior to the separation.Therefore, procedural and handling factors likely contributed to the reported event.According to the safety information in the instructions for use ¿prior to angioplasty, the catheter should be examined to verify functionality and integrity, and ensure that its size and shape are suitable for the specific procedure for which it is to be used.Do not use if product damage is suspected or evident.If resistance is felt upon removal, then the balloon, guidewire and the sheath should be removed together as a unit, particularly if balloon rupture or leakage is known or suspected.Proper functioning of the catheter depends on its integrity.Care should be used when handling the catheter.Damage may result from kinking, stretching, or forceful wiping of the catheter.Forceful handling can result in catheter separation and the subsequent need to use a snare or other medical interventional techniques to retrieve the pieces.Always verify integrity of the catheter after removal.¿ neither the phr review nor the product analysis suggests that the found damages could be related to the manufacturing process of the unit.Therefore, no corrective or preventive actions will be taken at this time.
