The following were reviewed as part of this investigation: patient severity, complaint and lot history review, applicable previous investigation(s), sample (if available), labeling, and applicable fmea documents.
Based on a review of this information, the following was concluded: the complaint of a damaged guidewire is confirmed; however, the exact cause could not be determined from the returned photograph.
One photograph of an accucath guidewire was returned for evaluation.
An initial visual observation of the photograph showed what appears to be a detached accucath guidewire in a clear plastic bag.
A bend was observed near the proximal end of the guidewire.
No details of the break site or the distal tip could be made out clearly in the returned photograph.
While the guidewire in the returned photograph appears to be detached and bent, it was not possible to determine the root cause(s) of the apparent damage.
Possible causes include retraction of the guidewire against the needle bevel, retraction of the guidewire against resistance, and sharp instrument damage.
As a note, the product ifu states: ¿do not force or retract the guidewire.
Retracting the guidewire may increase the risk of guidewire damage.
If the guidewire must be retracted, remove the entire device to prevent the needle from damaging or shearing the guidewire.
¿ a lot history review (lhr) review is not possible, as no manufacturing lot number has been provided by the complainant.
