As reported, the tip of the saber pta (3mm6cm 90) dilatation catheter has disassociated before introduction into the patient's artery.
There was no reported patient injury.
The device will be return for analysis.
Initially, the patient was hospitalized for arterial angioplasty transluminal of left leg and amputation of the third (3rd) toe left foot due to kidney failure chronic.

As reported, the tip of the 3x60mm 90cm saber percutaneous transluminal angioplasty (pta) catheter dilatation catheter was disassociated before introduction into the patient's artery.
There was no reported patient injury.
Initially, the patient was hospitalized for arterial angioplasty transluminal of left leg and amputation of the third (3rd) toe left foot due to chronic kidney failure.
One non-sterile saber 3mm6cm 90 was received coiled inside a plastic bag.
The balloon was already inflated.
Distal tip was received separated.
No other anomalies were noted in the returned device.
The unit was sent to scanning electron microscope (sem) analysis in order to analyze the potential cause of the separation.
Sem results showed that the distal and proximal sections of the separated tip presented evidence of elongations.
The elongations observed suggest that the tip¿s separated areas were induced to stretching/pulling events that exceeded the tip¿s material yield strength prior to the separation.
No other issues were noted during sem analysis.
A device history record (dhr) review of lot 17598461 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.
The reported ¿distal tip separated¿ was confirmed through analysis of the returned device.
However, the exact cause of the reported failure could not be conclusively determined during analysis.
Based on the limited information provided, procedural/handling may have contributed to the reported event as evidenced by the presence of elongations at the separated area during sem analysis.
According to the instructions for use (ifu), which is not intended as a mitigation, ¿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 dhr review nor the product analysis suggests that the event experienced by the customer could be related to the design or manufacturing process of the product.
Therefore, no corrective/preventive action will be taken at this time.
