Age at time of event: 18 years or older.(b)(4).Returned product consisted of an emerge balloon catheter.The balloon was loosely folded.The outer shaft, inner shaft, balloon and tip were microscopically examined.There are numerous hypotube and shaft kinks.The inner shaft is stretched in numerous locations.The inner shaft is buckled 2mm from the bi-component weld.There is an inner shaft puncture hole 13.5mm from the bi-component weld along with shaft buckling.There is an outer shaft puncture hole 1mm from the bi-component weld.The damage is consistent with the damage that is seen caused by use of a guidewire.Functional testing was completed using a thruway.014 guidewire, as the guidewire used in the clinical event was not returned for analysis.The thruway guidewire was inserted through the distal tip and could not advance due to the damage.There was no evidence of any material or manufacturing deficiencies contributing to the damage and the reported difficulty.The investigation conclusion is caused by other device as another device/drug/subsequent procedure caused the complaint event.(b)(4).
