The following were reviewed as part of this investigation: patient severity, trend analysis, applicable previous investigation(s), sample (if available), and applicable fmea documents.
Based on a review of this information, the following was concluded: the complaint of the guidewire removing the flow actuator from the catheter was confirmed and the cause appeared to be use-related.
The product returned for evaluation was one accucath peripheral iv catheter assembly.
The catheter was not returned for evaluation.
Usage residues were observed throughout the sample.
The safety button was depressed and the needle was fully withdrawn into the housing.
The wire exhibited a 90 degree bend approximately 2cm proximal of the coil.
The coils were misaligned but appeared intact.
The flow actuator was observed within the housing.
Microscopic inspection of the sample confirmed that the wire was intact.
Inspection of the flow actuator was unremarkable.
The retention features appeared well-formed.
It appeared that the removal of the flow actuator was caused by inability of the actuator to pass the bent region of the guidewire.
The guidewire bent and coil misalignment was consistent with attempted guidewire advancement into tissue or through a tortuous path.
The usage residue indicated that guidewire damage occurred during attempted device placement.
A lot history review (lhr) review is not possible, as no manufacturing lot number has been provided by the complainant.
